Chert is microcrystalline quartz - hard and chemically inert unlike the surrounding Redwall limestone which is soft and susceptible to dissolution by carbonic acid found in natural waters. (Photo by Jon Spencer)Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges. Rather than an anticipated limestone PeF value of about 5 b/e, the curve is confined to a range between 2 and 3 b/e. This unit is a cherty dolomite where the effect of chert (density higher than neutron density) is confounded by the effect of dolomite (neutron higher than density porosity).
