Cherty limestone

It was originally the name for chert found in chalk or marly limestone formations formed by a replacement of calcium carbonate with silica. Commonly found as nodules, this variety was often used in past times to make bladed tools. Today, some geologists refer to any dark gray to black chert as flint..

Resistance is the measured voltage divided by the current. This is Ohm's Law. Resistance will change if the measurement geometry or volume of material changes.This formation is composed of massive limestone, light-colored massive limestone marl, marl dolomitized limestone, and cherty limestone.
