Ice Age (Quaternary Glaciation) from receding flood adds
ice to Ararat summit helping seal petrified Ark as the dome builds up higher and higher
More pillow lava occurs when extruded under ice, snow and melting waters
shown by spheroidal weathering
Ararat grows under the pressure of lava possibly higher
than today when a deep-seated fracture from the intrusive force of a magmatic intrusion of granite or
trachyte or syenite causes the northeast side to explode 1-3 cubic miles of volcanic rock debris and whitish
toward northeast over 100 square miles creating the Ahora Gorge that shows the internals of the mountain
Doming effect is apparent when one views the same limestone formations on
all sides of Ararat as the bed
dips away from the mountain on the Turkish, Armenian, and Persian sides

The original mountain is coarse-grained porphyry with a light buff color
and much pyrite indicating a deep-seated
intrusive that cooled slowly, permitting the phenocrysts to form first then
the whole mass was uplifted
through the cover-rock allowing the remainder of the magma to cool more
quickly and form fine grained
crystals and glass. This inner core may represent the original mountain from creation.
The many small "parasite" cones on the slopes helps explain why
the ark may not have been destroyed
over time by volcanic activity: the pressure was vented from those
"parasite" cones, such that
there was no single main cone from which magma would spew out and bury
everything from the top
down
Ark
probably broke into pieces during the violent eruption of mountain either
Little
Ararat and other parasitic cones are of more recent origin because it is
smoother and less gullied and
eroded
