Chert gravel.

Fast moving water can carry materials of different sizes ranging from boulders and gravel to finer materials (sand, silt, and clays). Flowing water also sorts sediments by size and density. High-energy environments include river channels, beach and shallow offshore environments with high wave action, and wave-battered coral reefs (Figures 6-21 ...consists of 16.5 feet of chert gravel in a matrix of silty kaolinitic clay with thin irregular layers of iron oxide cement.

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 outcrop was a white to light gray gravel with a variety of subrounded to angular, pebbles and cobbles ranging from ½ inches to 20 inches in diameter. The pebbles and cobbles are composed of either a light gray, fossiliferous chert or black, denser chert, set in a light gray to white fine-grained silica and/or clay matrix.Chert occurs in carbonate rocks that are greensand, limestone, chalk, and dolostone formations as exchange mineral, where it is formed as a result of some type of diagenesis. if where it occurs in chalk or marl, it is called flint.

Chert is a sedimentary rock, mostly composed of silica. It is formed in the sediment precursors of limestone and chalk, mostly produced on the ocean floor. Microscopic organisms in the ocean have skeletons made of silica, which fall to the bottom of the ocean, dissolve, re-crystalize, and then petrify into chert.
