Cretaceous/Paleogene Boundary Cores

rig

14 holes at 7 sites were drilled in Fall 2008 to investigate the nature of the Cretaceous-Paleogene boundary in New Jersey. Drilling by the USGS drillers using use a truck mounted Multi-twin G-30 Drill (“Sonic Metaprobe”) resulted in 479.15 ft of core recovered from 516.4 ft drilled (91.3%). These cores will be available to the scientific community after the moratorium period. This research is supported by a grant from the NSF Sedimentary Geology Program.
