Geological narrative invited by David Middleton
In my latest article, How Local weather Change Buried a Desert at 20,000 Toes Below the Gulf of Mexico Seabed, we mentioned the division that opened up the Gulf of Mexico. In a single remark, TTY talked about a latest doc on long-extinct volcanic exercise within the jap Gulf of Mexico, which jogged my memory of the "volcano" drilled within the 1960s close to New Orleans. Once I googled volcanic rocks within the Gulf of Mexico, I found extra science fiction than science.
I’ll begin with science …
Cretaceous volcanoes within the Gulf of Mexico
Door Level is situated within the waters of the state of Louisiana, simply off the parish of St. Bernard, in an space thought-about freed from Mesozoic volcanic exercise.
Determine 1. Location map of the gate level. (Braunstein and McMichael, 1976)
The "volcano" of Door Level was found by Shell after they entered it in 1963.
Determine 2. Cross-section of the door-point construction.
(Braunstein and McMichael, 1976)
The construction of Door Level is technically not a volcano.
A properly of exploration, the Shell Oil Lease, State Lease No. 3956, situated off the parish of St. Bernard, Louisiana, was accomplished in 1963 at a complete depth of 8538 ft. The final 1300 ft of gap had been dug and drilled by way of Higher Cretaceous volcanic supplies. The placement of this properly is proven in Determine 1.
Pre-drilling seismic information revealed the presence on this prospect of intrusive supplies of barely larger density than surrounding sediments. The gravimetric information right here outlined a low most and no salt could be current.
Igneous materials consists of angular fragments of weathered porphyry base rocks. Within the cores, it has been discovered to be uniformly adhered and cemented by scattered calcite. Radioactivity courting set a minimal age for crystallization of this rock at 82 months + eight years, or within the Center Cretaceous (Austin). The obvious density of igneous rock ranged from 2.02 g / cc upwards at 2.53 g / cc to the underside of the properly.
Three accumulations of fuel, with a complete thickness of 38 ft, had been encountered within the Miocene. part between 5092 and 6219 ft within the Shell properly. Fuel sands weren’t current in two different wells drilled later in the identical construction (Fig. 2).
Though Higher Cretaceous volcanic exercise is widespread in northern Louisiana, in addition to in Mississippi and the southeast. from Louisiana within the Gulf of Mexico, the Door Level prospect is situated in an space beforehand designated free from volcanism.
Braunstein and McMichael, 1976
Though it’s clearly composed of reworked volcanic supplies.
The Door Level construction crossed by the Shell Oil S.L. 3956 eh properly no. 1, situated off St. Bernard Parish, Louisiana, represents the singular presence of igneous rock discovered within the subsoil all through the area off the GoM and courting again to the Cretaceous. Recognized within the literature as a volcano, sill or different fundamental intrusive / extrusive factor, with an age of 82 ± eight years, Mya, the "volcano level" of the gate, has been little studied since its discovery within the 1970s.
A preliminary examine of the nucleus exhibits that the unit consists of volcaniclastic rocks. The preliminary geophysical log examination supplied by Shell Oil and Drilling Data exhibits a big and obvious shift in resistivity, with malignant or absent deviation from the spontaneous potential curve. The sequence of volcanic rocks extends vertically over at the very least 396 m, with no recognized base, and the singular core interval is taken from the ultimate eight.5 m. Preliminary petrographic examination revealed the huge presence of unlaminated polymictic agglomerates and laminated volcanic ash. Basalt pebbles alternate sequentially with the finer grained volcanic ash packages. The dimensions of grains for igneous pebbles in agglomerates varies in excessive diameters starting from a most of 5 cm to a minimal of 1 to 2 cm. Sedimentary constructions are absent within the coarser sequences, however are uncovered within the volcanic ash beds, within the type of crossed layers. The composition of clastic populations varies from sedimentary rock fragments to igneous rocks of curiosity. Possessing a porphyritic texture and an angular look, the clasts comprise seen clinopyroxene phenocrysts in an aphanitic landmass; CI> 90.
These outcomes counsel that the pebbles originate from a number of volcanic facilities and have undergone a multi-stage cooling historical past. Coupled with the presence of calcite cement, the cross layer is indicative of a marine or fluvial deposition system. We’re in a position to reconstruct a regional historical past of episodic volcanism within the nascent Gulf of Mexico Rift on the finish of the Cretaceous.
Session No. 320 – Stand No. 503
Door Level is almost definitely a diapir of salt or shale (perforation construction) that carried volcanic materials with it.
This isn’t the one volcanic curiosity within the northern Gulf of Mexico.
Determine three. Location maps for Door Level (left) and Alderdice Financial institution (proper, Rezak & Tieh, 1984). Click on for the picture.
The Alderdice Bench is a diapir of salt, which appears to have carried a number of giant blocks of basalt on the seabed.
A basalt outcrop was found on Alderdice Financial institution, on the outer continental shelf of Louisiana. Basalt exhibits an age of 76.eight ± three.three × 106 years. Textural, mineralogical and chemical traits point out that it’s an alkaline basalt of shallow intrusive origin. It was in all probability delivered to the seabed by salt tectonics and uncovered as a result of dissolution of salt.

The Alderice Financial institution is situated roughly 52.5 kilometers southeast of Sonnier Banks, about 60 km northwest of McGrail Financial institution and 157 km northeast of East Flower Backyard Financial institution. The shoreline is an east-west oriented oval and covers an space of roughly 16 km2.
Three spectacular basaltic arrows of Higher Cretaceous origin (roughly 77 million years previous) are discovered at Alderdice Financial institution. These are the oldest identified uncovered rocks on the continental shelf off Texas and Louisiana, and distinctive geological options for this area. The outcrops attain a peak at about 50 m (165 ft) and their base at about 73 m (240 ft).

Analyzes of latest gravity, magnetic, and high-resolution surveys have pretty clearly revealed the traditional rift system within the jap Gulf of Mexico (Lin et al., 2019).
A geometry of Cretaceous ridges and cretaceous zones, early Jurassic early on the earth, within the western Gulf of Mexico (GOM) and segments of extinct seabed ridges within the east of the Gulf of Mexico (EGOM) have already been recognized utilizing the vertical gradient of gravimetric information from the open air derived from satellites. Round gravity anomalies and magnetic anomalies above the middle of the unfold crest segments are interpreted as giant volcanic facilities that erupted inside a late Late Jurassic late Cretaceous,

It’s moderately stunning that these volcanic curiosities didn’t entice extra consideration from the analysis … Perhaps if there was oil in basalt, they l & rsquo; would have … 😉 Nevertheless, they’ve lately caught the eye of "varied media".

Again on January 11, we’ve reported to the PNA that a number of days earlier than a 7.6-magnitude earthquake within the Caribbean Sea, inflicting a tsunami warning in a number of Caribbean islands, ocean waters have abruptly and mysteriously "disappeared" into extra distant places 3000 km north and south of the epicenter of this earthquake.
In response to videomaker MrMBB333 we in a video we used on this story, "the water is attempting to inform us one thing".
Effectively, if the water abruptly and mysteriously disappeared into the Gulf of Mexico and the Pacific Ocean, she was attempting to inform us one thing then certai
As we see MrMBB333 within the 1st video beneath, one thing extremely unusual is going on within the Gulf of Mexico. with air temperatures recorded at greater than 130 levels repeatedly over the previous week, with temperatures oscillating between "regular" temperatures within the vary of 75 to 80 levels earlier than a sudden taking pictures as much as at the very least 133 levels as we see within the movies and the second picture beneath.
On March 19, 2013, Nesara Information printed an article entitled "A buried volcano in southeastern Louisiana" during which he advised us in regards to the proof of 39 Higher Cretaceous volcanic exercise is widespread in Louisiana in addition to in Mississippi and southeastern Louisiana within the Gulf of Mexico.
Referred to as "Door Level", proof of volcanic exercise was found in an space beforehand known as being freed from volcanism as seen within the following picture beneath. It’s fascinating to notice that this "igneous free zone" consists of areas the place we’re presently experiencing excessive temperature peaks within the Gulf of Mexico, as proven within the above photos and movies beneath.
May an historic, lengthy dormant volcano be underneath the water of the Gulf of Mexico, abruptly coming again to life, its breakdown inflicting these temperature spikes we’re witnessing? Far more on the idea beneath with the proof that we is likely to be about to witness one thing surprising if an extended dormant volcano within the Gulf of Mexico awoke.
The article presents this image … Does this sound acquainted to you?

Whereas the "Ring of Hearth" is warming up with volcanoes across the planet now erupting and that massive earthquakes point out that a fair greater earthquake is unquestionably forward of us, as we hear within the third video beneath from Infowars, it’s not misplaced on those that are attentive to the truth that the Gulf of Mexico borders the "circle of fireside", as we see within the following image beneath [1945900319459)ThelargestgulfintheworldisitacoincidencethattheGulfofside'"WhathappensjusttoalignwiththeCaribbeanIslands?"WefinditveryinterestingthetheoryofCaribbeanoriginsknowinginparticularthattheCaribbeanisa"greatigneousprovince"createdavolcano
that we don’t see any submarine volcano within the Gulf of Mexico, what’s going to occur if all of the Gulf of Mexico was the "mouth" of the traditional volcano and the "supply" of the Caribbean islands within the time of their creation? between 69 million and 139 million years? Though Wikipedia signifies that the islands could be associated to the Galapogos hotspot, which is sort of far aside, is the reality nearer to dwelling?
Though we cannot see them, submarine volcanoes are usually not new and, because the 2014 LA Instances reported, scientists had lately created a high-resolution map of the ocean ground, revealing hundreds of submarine mountains extinct and submarine volcanoes that had by no means been identified earlier than. And though their map is twice as correct as some other map of the ocean ground, they rapidly acknowledged that it might solely resolve options of at the very least one kilometer or extra.
Enter this Might 2017 story from Nationwide Geographic that makes use of a brand new ocean ground map created by a authorities company that has for essentially the most half by no means heard of "Bureau of Ocean Administration". "ocean vitality", however that we see within the photograph. As for the photographs, we all know little or no in regards to the ground of the Gulf of Mexico, with the fitting picture the very best high quality decision we’ve now, in comparison with the left picture illustrating what we knew earlier than.
All of the information Pipeline
It appears that evidently the map of the key authorities company is an indication of a volcano.
Does anybody acknowledge this? Excessive decision bathymetric mapping was mentioned right here: U. S. BOEM publishes a most decision bathymetric map of the Gulf of Mexico … Evah! Watts up with that? Might 30, 2017. The particular picture is extracted from an article of Eos and represents the expression of a salt dome on the seabed, bordered by a retention basin of salt.
Determine 7. "The Horseshoe Basin within the Western Gulf of Mexico, In comparison with the Support (Left) of NOAA's Historic Bathymetry Map and the New BOEM Map (at proper). The basin comprises a dome of salt in its heart and is flanked by salt leaves. The motion of salt is clear from the community of faults and cracks on the seabed across the basin, in addition to sediment particles flows that fall on the slopes of the basin and on its soil. Credit score: BOEM "(Eos)
The high-resolution bathymetric map is derived from 3D seismic surveys, which give a comparatively clear visualization of the salt domes, sills, massifs, and different halokinetic options of most hydrocarbon traps within the Gulf of Mexico. the tough geomorphology of the seabed on the continental slope. Calling this proof of a volcano is tantamount to saying that crater hunters encircle rounded options on satellite tv for pc photos and declare them as affect entities … with out ever taking a look at geology.
Oh … However that improves (or worsens relying in your viewpoint) … That is from "Punch on the information, the place the general public fears to be feared" ……
Scientists warn the & # 39; Supervolcano & # 39; of the Gulf of Mexico about to erode
15 March 2018 Sean Adl-Tabatabai
 Scientists have warned that extraordinarily excessive temperatures within the Gulf of Mexico final week could possibly be a forerunner of a deep underwater supervolcano rash.
Scientists engaged on the RFS Viktor Leonov CCB175 recorded that water was disappearing off the South American nation of Ecuador. January fifth. Three days later, on January eight, the waters started to vanish alongside the North American coast of Florida, which was adopted 24 hours later by a large magnitude 7.6 earthquake within the adjoining Caribbean Sea. on the Gulf of Mexico.
The common sea floor temperature of the Gulf of Mexico by no means falls beneath 23 levels Celsius (73 levels Fahrenheit) throughout the winter for the primary time in report final yr, and of which advert zone "has reached its largest dimension in historical past, scientists aboard the analysis vessel declare that no proof permits for assume these occasions are on account of local weather change.
In contrast to their Western counterparts, these Russian thriller scientists, return into the older tales and myths of our Earth to see if parallels could be drawn with what is going on now – and this has led to an examination of the Mayan peoples who lived on this area all through antiquity – even as much as the American states of Florida and Georgia.
Lyndon DeSalvo, researcher at Carleton School, describes it in his analysis article entitled "Bloody Earth: Volcanoes: Prototypical Mountains of the Mayan Cosmological Previous", the tales of Mayapeopians and their legends inform the story of Gulf of Mexico because the place the place the mountains come – and likewise disappear – and the one clarification of recent instances An individual describes the actions of a volcanic caldera, ie an important melancholy much like a cauldron that types after evacuating a chamber / magma tank throughout a supervolcan eruption.
Ignoring the traditional legends of the Mayan folks, its tales and myths that the Gulf of Mexico would possibly truly be an enormous volcanic caldera, Western scientists have lengthy sought to know the way it grew to become much like that of this was the final try that occurred in 2002, when American geologist Michael Stanton printed a speculative essay suggesting an (comet / asteroid) affect origin for the Gulf of Mexico – however that each one geologists world wide have rapidly dismissed, believing that he had no credibility.
By getting nearer to the traditional tales of the Mayan folks, American geologist David Prior, a well-known geologist, grew to become the primary scientist to doc volcanic eruptions whereas conducting analysis at Louisiana State College (LSU). within the Gulf of Mexico – and the invention of which he spoke in his 1989 scientific analysis paper titled "Proof of Sediment Eruption within the Seabed, Gulf of Mexico".
Based mostly on Mr. Prior's scientific proof of volcanic eruptions within the Gulf of Mexico in 2003, "asphalt volcanoes" – which we had by no means heard of earlier than – additionally shaped in these waters – and that led to huge efforts to redefine the map all of the oceans of the world to find what number of submarine volcanoes there are – and as soon as accomplished, in 2014, revealed hundreds submarine mountains and extinct volcanoes that had been beforehand unknown.
This month of Might (2017), the primary in The People lastly launched an in depth map of the Gulf of Mexico seabed – and whose astonishing discoveries revealed that its deep ocean ground was dominated by canyons , ridges and faults – some fault traces of which prolong to the Jackson, Mississippi, volcano – and with nice conviction that new discoveries will quickly join the whole south-east. from america to the fearsome trans-Mexican volcanic belt.
At this level, my mind began to move from my left ear. If anybody wants me to clarify why nothing within the passage above is proof of volcanic exercise within the Gulf of Mexico, I might be blissful to take action within the feedback part … Tip: sediment expulsion, mud volcanoes and asphalt volcanoes are usually not associated volcanism, magma or different igneous course of … at the very least not within the Gulf of Mexico.
From abiotic oil to the Weekly World Information, to the motion of the Earth's crust to the Gulf of Mexico's supervolcans … Why do they nearly at all times quote "Russian scientists"?
In contrast to their Western counterparts, these Russian scientists, confronted with such mysteries …
Within the case of the Weekly World Information, it was normally "based on Russian scientists, as reported by Swedish scientists" (Full in white: an oil rig drilled in Hell, a bomber of the Second World Warfare world was in a crater), Moon, Batboy advises Invoice Clinton on the 1996 elections).
Why did I take the time to demystify this nonsense?
As a result of it was each 1) enjoyable and a couple of) straightforward … Apart from minor cerebral hemorrhage.
It additionally appears that a few of AGW's skeptics have a tendency to maneuver in direction of another "science" in areas aside from the local weather. This should be carried out fastidiously. And generally, even cautiously, this will result in malicious assaults by Warmunists. Rejecting the so-called scientific consensus on AGW doesn’t logically require that skeptics reject all scientific consensus. Though science just isn’t a consensus-building course of, most scientific consensus outcomes from examined and confirmed hypotheses, resulting in scientific theories that show predictive talent … Gulf of Mexico Formation Principle predicted that the proof of early Jurassic finish The rifting and volcanic exercise of the Cretaceous could be situated at its later location.
