Globally
warm temperatures and elevated atmospheric CO2 in the Paleocene make
this epoch of particular interest for understanding greenhouse worlds; yet, terrestrial
records from this interval are rare, particularly in North America. In this study, Torres and Gaines examine morphology, clay mineralogy, and bulk
geochemistry
of paleosols from two members in the late Paleocene Goler Formation of Southern
California to investigate paleoclimatic change during deposition. The results reveal a shift in pedogenic
processes concomitant with changes in provenance and sedimentation rate. These data are interpreted to suggest that paleotopographic
change, driven by regional tectonic activity, was an important control on local
climate and pedogenic processes.
