Three researchers from California State University, Bakersfield will present their findings at The Geological Society of America annual meeting in Denver.

Professor Rob Negrini, graduate student Brian L. Taylor and adjunct faculty member Manuel R. Palacios-Fest, from the Physics and Geology Department at CSUB will each present a different topic at the 119th annual meeting of American geologists.

The meeting is scheduled Oct. 27-31 at the Colorado Convention Center in Denver, and is one of the most important geological events of the year. Some 6,300 geoscientists are expected to attend the conference.

Negrini will present his findings that show evidence of a long-lived lake that occupied the Carizzo Plain during the Pleistocene era. Also, the two cores extracted from the Carizzo Plain indicate a 50-ft-deep pluvial lake that formed in that region during the most recent ice age. Pluvial lakes are lakes formed in closed basins as a result of increased precipitation and reduced evaporation, such as during the glacial eras of the Pleistocene epoch.

Taylor will discuss the mineralogical changes that have occurred in a west-side oil reservoir since the sediments were deposited during the Eocene geologic time period. These changes are important because they affect the way that oil flows through and accumulates in the sandstone. His findings suggest that significant changes have occurred and that these changes are different at different burial depths, thus explaining differences in reservoir quality across the field.

Palacios-Fest will present his findings from two cores that he extracted from the west side of the Tulare Lake near Kettleman City that show evidence of four different species of freshwater crustaceans that existed up to 60,000 years ago.
