content: Huronian Chert, also known as Yellow Onondaga and Delaware-Onondaga, is a glacial pebble chert. It is white, light gray, light tan, yellow, light gray and brown, sometimes mottled with light brown carbonate. When heat-treated the white color variety changes to tan, brown, red dark red, red with jasper-like appearance. When weathered it develops a hard, light brown cortex or becomes grey to grey white. May have cephalopod, gastropod, bivalve, siderite, or druzy quartz inclusions. Frequently coated with glauconite. It has a smooth, very fine grained texture. Deposits include nodules and glacial drift.
