Title:	2-D MODELING OF SOUTHERN OHIO BASED ON MAGNETIC FIELD INTENSITY, GRAVITY FILED INTENSITY AND WELL LOG DATA
Author:	Harbi, Hussein M
Description:	Results of magnetic and gravity data forward modeling, combined with existing well-log data, geologic information and seismic data provide new insights into the structural complexity of the Precambrian basement beneath southern Ohio. These results support previous hypotheses regarding the spatial extent of the Grenville Front Tectonic Zone (GFTZ). The set of nine modeled profiles also provide greater evidence that the GFTZ consists of a 25-35 km wide zone of east dipping structures in the Precambrian basement extending from mid- to southern Ohio. A previously identified anorthosite body is modeled at mid- to upper-crustal depths, but having an approximately 8o eastward dip. Farther east, the previously identified, west-dipping Coshocton zone is modeled as a set of structures that deepen to the west from mid- to lower crustal depths beneath east-central Ohio. The modeling further supports the contention that the Coshocton zone is associated with the New York-Alabama magnetic lineament.
