Lithologic Examination of Cores and Well Cuttings from the Antrim Shale

摘要

Cores from three wells and a portion of the core of a fourth well drilled in Sanilac County, Michigan were subjected to lithologic examination. These cores began in the Bedford shale and extended through the Antrim shale into the Traverse Formation. The predominant minerals were illite, chlorite, dolomite and quartz. Numerous fossils were observed. (ERA citation 05:034572)
