Re: End-K carbon

A quick check shows no oilfields or sedimentary
basins/source rocks in the area of the Chicxlub
impact.  The nearest oilfields are in Neogene
structures.  A follow-up study might find
residual hydrocarbons in the carbonate breccia
which is believed to have been created by the
impact.

Reference: The Western Gulf of Mexico Basin, AAPG
Memoir 75, 2001. Most relevant articles are:
"Pimienta-Tamabra(!) - a giant supercharged
petroleum system in the southern Gulf of Mexico,
onshore and offshore Mexico" and "Classification
and origin of petroleum in the Mexican Gulf Coast
basin: an overview".
