Folks, an interesting looking talk over at Del Mar coming up next
Friday--take a look. Perhaps if there is enough interest, a TAMUCC
van could be taken.<br>

geologic field study of outcrops on the island of
Barbados was conducted by an Exxon research team
including this author. Deep-water sandstones were
described to compliment the company’s worldwide
exploration, production, and reservoir
modeling portfolio. Easily accessible exposures of
Eocene deep marine clastic sediments, oil production
on the island, and the complex geologic origin of
Barbados distinguish it from the nearby volcanic
islands in the southern Caribbean Sea. <o:p></o:p></span></b></p>

style="text-align:justify;text-autospace:none"><b><span
style="font-family:"Arial","sans-serif"">This
166 sq. mi. island exists because of an emerging
accretionary prism of flysch sediments, presumably
shed from South America, now positioned in the
Atlantic Ocean above the subduction zone of the
convergent Atlantic and Caribbean oceanic plates. To
the west, the Windward Islands of the eastern
Caribbean Sea form an island arc corresponding to the
trace of the subducted Atlantic plate.

style="font-family:"Arial","sans-serif"">Within
the Scotland District of Barbados, which is located
along the central Atlantic coast, several spectacular
turbidite outcrops provide windows into the
reservoir-quality facies of submarine fans. The
ranges and juxtaposition of grain size, bedding
thickness, and stacking pattern of Bouma-classified
turbidites aid in assessing the relative position of
each outcrop within a generalized fan model. Steeply
dipping and overturned beds, thrust faulting, and
shale diapirs confound the direct correlation of
outcrops as a singular fan but attest to the
composition and complexity of the accretionary prism.

style="font-family:"Arial","sans-serif"">Pleistocene
and younger carbonate reef complexes have repeatedly
and episodically formed atop the emerging Barbados
prism creating broad limestone terraces and
fresh-water aquifers vital to the island. Mud
volcanoes and imbricated thrust nappes in the clastic
prism support the oldest limestone terrace and form
the highest (300+ m) elevations of the island.
Extensive karst geomorphology, including networks of
caves, sinkholes, and collapse gullies, are common to
the uplifted limestone terrains.

exploration efforts in the waters around Barbados have

was conducted by this author to the island in order
to: revisit key Scotland District outcrops; reconsider
earlier interpretations; assess the quality of the
exposures for further study; and to photographically
catalogue these outcrops and the other interesting
geomorphologic features on the Island. </span></b><b><span
