Post-Knox unconformity-significance at Unionport gas-storage project and relationship to petroleum exploration in Indiana
The post-Knox unconformity provides the principal trapping conditions for underground gas storage at Unionport in Randolph County. Erosion remnants of the porous Knox Dolomite protrude upward into theverlying impermeable Black River Limestone. The erosion-induced irregularity of the post-Knox unconformity is only slightly reflected on the top of the Trenton Limestone. The composite thickness from the top of the Trenton to the top of the Knox ranges from 400 to 530 feet at the Unionport gas-storage project. Petroleum has been produced in Indiana, Ohio, Kentucky, and southern Ontario from erosion remnants apsocated with the post-Knox unconformity. We feel that petroleum deposits under similar geologic conditions exist in Indiana and that the crestal area of the Cincinnati Arch provides the most favorable general area for exploration. 10 figures.
