Indiana's Trenton limestone geology

The term Trenton limestone is the stratigraphic designation for a unit in northern Indiana composed of both limestone and dolomite. The Trenton is Middle Ordovician (Champlainian) in age and related clearly to the position of the Cincinnati arch. The limestone is thickest in northern Indiana and thins toward the southeast. Isopach maps of the Trenton limestone and the Maquoketa group above it indicate that the Cincinnati arch did not exist as a positive structural influence to sedimentation until after Ordovician time. Preliminary results of an ongoing study of the Trenton reservoir suggest that second and tertiary recovery there will be limited. Because of the low density of drilling on the Trenton's north flank, however, large areas remain virtually untested; more structural or stratigraphic traps similar to those of the Urbana field could exist. A better definition of the distribution of the dolomite facies will lead to a more accurate assessment of the Trenton's potential.
