Limestone is an interesting clastic rock, composed of particles derived either by precipitation of calcium carbonate from solution (oolites) or from the carbonate shells of microscopic marine organisms.

Chert gravel clasts are typically highly weathered and exhibit a thick, porous, chalky, and tripolitic cortex. In some instances, the chert gravel is weathered and leached to such extremes that it is not a viable lithic resource. chert originates in Bigby-Cannon limestome in Middle Tennessee. Incidently, Bigby-Cannon chert looks very much like Tyrone chert from Kentucky. The most accu-rate method of identifying chert is to find it still within the original matrix where it was formed. If the sample is incased in Bigby-Cannon limestone then it is Bigby-Cannon chert.

The ancient gravel deposits are exposed in road cuts and gravel pits, where collection of flint cobbles is feasible in some areas. I’d pick a less traveled gravel road rather than a major highway, for safety if nothing else. Based on my observations, almost half of the ancient gravel consists of flint or chert, with lesser amounts of limestone.

Chert has four diagnostic features: the waxy luster, a conchoidal (shell-shaped) fracture of the silica mineral chalcedony that composes it, a hardness of seven on the Mohs scale, and a smooth (non-clastic) sedimentary texture. Many types of chert fit into this categorization. 01 of 16 Flint Nodule James St. John/Wikimedia Commons/CC BY 2.0

Lower part ranges from grayish-red, medium-gray, pale-brown, and greenish-gray to pale-green mudstone and siltstone containing disseminated subangular to subrounded chert-gravel, quartz-sand lenses, and chert-pebble conglomerate. Lower contact unconformable. Thickness ranges from 0 to 46 m (0-150 ft).Eldorado soils are on sideslopes of hills in the uplands. Slope ranges from 1 to 25 percent. The soils formed in residuum weathered from cherty limestone. Many areas have a few inches of soil from chert free limestones or chert free sediments. Mean annual precipitation ranges from 940 to 1090 mm (37 to 43 inches).Chert-breccia. Chert-breccia is defined as autoclastic breccias, in which both fragments and matrix consist of microcrystalline quartz (Fairbridge, 1978). Chert is a common component of many carbonate sequences. It is a very good indicator of the depositional environment or the prevailing diagenetic conditions.Feb 2, 1998 · Stay In Touch With MDC THIS CONTENT IS ARCHIVED Some kinds of rocks are hard to get to know personally.
