GONZALEZ, LA. 1991. Carbon and oxygen stable isotopes in the toa-baja well, puerto-rico - implications for burial diagenesis and hydrocarbon generation rid D-5476-2011. Geophysical Research Letters 18 (3) (MAR): 533-6.
Abstract:
The Toa Baja Well was drilled on the coastal
plains of northern Puerto Rico with a total depth of 2705m
[Larue, 1990]. Interstratified limestone, quartz-bearing
calcareous sandstones, and shales dominate the uppermost 580
m and are separated from underlying rocks by an
unconformity. Below this unconformity continuing tototal
depth, lithologies encountered consist of volcaniclastic
sandstones/siltstones, pelagic carbonates, volcanic flows and
either plutonic rocks or coarse-grained immature sandstones
derived from plutonic bodies....
