Abstract: Geology of Bering Shelf
By
The present Bering Shelf is the largest untested,
contiguous marine area in the free world that is drillable with
today's technology. The present Bering Tertiary basins have
an optimum potential for sizable accumulations of hydrocarbons.
The present shelf edge approximates the position of the
Cretaceous shelf edge. The tectonic evolution of the shelf
has made correlation of the geologic history of the Mesozoic
onshore with the offshore impossible. The formation of large
shelf edge tensional basins (Navarin and St. George),
immediately after plate neutralization, suggests that common
solutions of pull-aparts and/or arc related basins are
inadequate to explain the geologic setting. Apparently, the
Kula plate interface vacillated between subduction and
transform phenomena during the Mesozoic. Neutralization
occurred in early Tertiary time when the Aleutian Arc was
interposed between the tip of the Kula plate and its spreading
center (bulk of the plate).
The best geologic analogs to the Navarin and St. George
basins are the Gulf Coast Interior Salt Basins. End_of_Record - Last_Page 3---------------
