  Lost City Expedition: The Rocks That Make up the Atlantis Massif
The Atlantis Massif rises 14, 000 feet above the surrounding seafloor.
Faulting and mass wasting (land slides) associated with the Atlantis Transform Fault or Fracture Zone, have dissected the mountain, resulting in a rugged and embayed southern face.
Harzburgites: From looking at the mantle rocks we recovered from the Atlantis Massif, we see that they are made up of about 10-15% diopside, and 85-90% olivine, with a little bit of chromite.

 Massif - Wikipedia, the free encyclopedia
In geology, a massif is a section of the Earth's crust that is demarcated by faults or flexures.
One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France.
In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain.

 Strain localization on an oceanic detachment fault system, Atlantis Massif, 30°N, Mid-Atlantic Ridge
Microstructural observations, mineral chemistry, and the spatial distribution of deformation fabrics recorded in outcrop samples collected from Atlantis Massif, the active inside corner high at 30°N, Mid-Atlantic Ridge, suggest that strain is localized near the subhorizontal domal surface hypothesized to be an exposed detachment fault.
Localization of brittle deformation fabrics near the upper surface of the massif supports the hypothesis that it is the exposed footwall of a detachment fault.
The structural evolution of Atlantis Massif is therefore analogous to a continental metamorphic core complex.

 Lost City Expedition: The Atlantis Massif
The Lost City Vent Field stands on top of a very peculiar mountain on the seafloor called the Atlantis Massif ("massif" is a name for a very large mass of rock).
These are probably giant scratch marks that hint that the top of the massif is a giant fault zone formed as masses of the Earth slid past one another.
These pieces of evidence suggest to us that the rocks that make up the Atlantis Massif once formed under the rift valley of the Mid-Atlantic Ridge a few miles away, but were pulled out from under the rocks at the surface- like pulling a rug out from under a piece of furniture.

They and their colleagues had intended to study faults and fissures at the western end of the Atlantis Transform where that slipping fault links with the offset continuation of the Mid-Atlantic Ridge to the south.
Tobi reflections there, combined with sonar mapping they did of the structure's underwater topography - or "bathymetry" - revealed the strange corrugations running along the dome's abnormally smooth top, and few signs of the volcanic activity expected on the flanks of the spreading, crust-producing ocean ridges.
Atlantis was just not available for work on the Atlantic until now, on the way back to its homeport at Woods Hole just before Christmas.

The position as the continent Atlantis occupied, is that as between the Gulf of Mexico on the one hand - and the Mediterranean upon the other.
One of the hypotheses for the formation of the Atlantis Massif proposes that the Atlantis Massif is rising along faults, such as a detachment fault on the east side of the Massif.
A massif (mas-sif') is a massive topographic and structural feature, especially in a mountain belt, commonly formed of rocks more rigid than those of its surroundings.

The Atlantis Massif is at the lithosphere plate corner bounded by the Mid-Atlantic Ridge spreading center and the transform.
The massifs along the northern side of the transform were all created by seafloor spreading at this corner and then carried along westward as new seafloor was made at the spreading center.
If the Western Massifs geology is similar to the Atlantis Massif, we would expect to find a low-angle fault zone near the top of the south wall and steep faults that control hydrothermal venting.

I visited Atlantis Massif in fall of 2004 on a cruise of the RV Atlantis.
Atlantis Massif is a domal sea floor mountain with nearly over 4000 meters of vertical relief (that's about 1.5 Pikes Peaks).
The upper surface of Atlantis Massif is now believed to be an exposed low angle normal fault, which uplifted rocks from the Earth's mantle to their current mountainous exposure.

Over 3 km of relief remains at the western massif and the 1050 m peak is 13 km north of the fracture zone (FZ) trace.
Broad shelves characterize the lower slopes of the western massif, within 5-7 km of the trace, and a steep, several-hundred-meter high scarp marks the southern limit of the dome top.
New images display this morphology and comparison with Atlantis Massif focuses on similarities (width and relief) and differences (relation between the peak and the southern limit of the dome, for example) in the current structure of the two oceanic core complexes.

Life without light Geologically, the Atlantis Massif was created by an earthquake fault that brought a large chunk of the earth's mantle close enough to the surface that seawater could come into contact with it.
The mantle is the portion of the earth's interior that lies directly beneath the crust, which is much thinner beneath the oceans than beneath the continents.
Not far from the Atlantis Massif lie several similar mountains, and with a little bit of luck, she hopes to prove that the Lost City is by no means unique.

 Augusta Georgia: Technology:Huge columns discovered deep under the Atlantic 07/15/01
The pale chimneys, delicate flanges and mounds are not relics of a lost civilization but the patient accumulation of minerals carried by seawater warmed as it reacts with heat generated in Earth's crust, scientists report Thursday in the journal Nature.
The spreading and decay of the Atlantis Massif over the past million years has worn the mountain down to its underlying mantle rocks.
There are three similar mountains subject to the same sort of fracturing within just 50 miles of the Atlantis Massif, and probably thousands of other sites along the 6,200-mile-long Mid-Atlantic Ridge.

It was held up by an overheated motor that controls the movements of the "bow thruster," a special propulsive unit that allows Atlantis to turn its front, or bow, as well as its rear, or stern.
That happened after an attached "clump weight" was also lowered to pull the neutrally buoyant sonar towards the bottom, even as it's umbilical cable - playing out and in from a projecting reel - kept the whole ensemble linked to the ship.
Working on a map based on her 1996 bathymetric data, Blackman had earlier used colored grease pencils to lay out a set of tracklines that would make the sonar straddle the ridge's contours for a total distance of about 124 miles at a speed of about 1 knot over 4 ½ days round-the-clock towing.

 "City" of Ancient Rock Found at Bottom of Atlantic Ocean
Nicknamed "Lost City" in honor of the fabled Atlantis, it differs from deep-sea volcanic vents previously found and may harbor new primitive forms of life.
Now, researchers probing the ocean bottom have found 18-story-high towers of stone deep in the ocean near a section of volcanic fault ridges that extend for 6,200 miles along the Atlantic Ocean floor.
The majestic height of the two dozen stone structures and their location on a seafloor mountain named Atlantis Massif inspired the scientists to name the area "Lost City," in honor of the fabled, flooded city referred to by Plato.

 Structure of oceanic core complexes: Constraints from seafloor gravity measurements made at the Atlantis Massif
Using the DSV Alvin, the relative seafloor gravimeter ROVDOG was deployed at 18 sites on the Atlantis Massif (located at the ridge-transform intersection of the Mid-Atlantic Ridge and the Atlantis Transform Fault near 30°N, 42°W).
A series of quasi 3-D forward models suggests that symmetric east and west-dipping density interfaces bound the core of the massif with dip angles of 16°–24° in the east and 16°–28° in the west, creating a wedge with a density of 3150–3250 kg/m
The dip angle in the east is steeper than that of the surface slope, suggesting that the detachment fault surface does not coincide with the density boundary.

But the new vent found atop the seafloor mountain Atlantis Massif, is nearly 10 stories taller.
Because the Atlantis Mountain area has such deep fractures, the crust doesn't layer the mantle in parts, exposing raw minerals like olivine to sea water.
Just within a mere 50-mile radius of the Atlantis Massif are three similar mountains subject to the same fracturing, the same intrusion of seawater and perhaps the same reactions with mantle material.
