The Kinzers Formation is a geologic formation in Pennsylvania. It preserves fossils dating back to the fourth stage of the Cambrian Period.
The base of the Kinzers Formation is primarily a dark-brown shale. The middle is a gray and white spotted limestone and, locally, marble having irregular partings. The top is a sandy limestone which weathers to a fine-grained, friable, porous, sandy mass. Wilshusen formally divided the Kinzers into three members along these lines in his 1979 map of York, Pennsylvania. The members are called the Earthy Buff Limestone Member, Pure Limestone Member, and Shale Member.
