THE FRANKLIN MINING DISTRICT
The hypothesis that the zinc ores were originally sediments deposited with the enclosing limestone and since metamorphosed with it was first proposed by Kitchell (72) in 1855 and was maintained by the geologists of the New Jersey Survey as late as 1896. It is difficult to establish, as there is no way of determining whether the layering of the ore is parallel to the original bedding of the limestone, and it does not explain the structure of the Sterling Hill deposit as now developed by more recent mining operations.
