Descr: Wright State geophysicists have for several years been exploring the Precambrian of the western Ohio region with industry scale seismic profiles. These research/educational seismic profiles serve to both study the existance and nature of basins beneath the region but also to give students experience in seismic equipment deployment and operation. This summer we plan to collect an industry scale seismic profile at a drill hole in easternmost Indiana where carbonate rocks were reportedly recovered from beneath the Mount Simon SS, the basal unit of the Paleozoic platform cover in the region. Other seismic profiles in the region have revealed strong reflectors below the Paleozoic platform cover, but commonly these are interpreted as mafic sills or flows. This project is to explore whether any reflective sequence is associated with the pre-Paleozoic carbonate rocks recovered from this well; and, if so, whether it might suggest that carbonate strata may be more widespread in the region than currently recognized.
