Lithology and environment
Primary lithology: "shale"
Lithology description: Plant materials come from light ash-colored somewhat arenaceous shales with minute particles of mica. Portions are massive, sandy and darker. Black coaly shales.
Geology comments: McClelland's Shaft- the basin affects surface topography as a slight sink. Occurs in loose layers of chert brecciated in situ and alternate limestone strata. The bottom of the depression is covered by loose chert. The shales, in a lenticular body, of about 10 feet in thickness very convex below and slightly concave above. At this level the basin iss about thrity feet in diameter.
Modes of preservation:adpression,replaced with pyrite,replaced with other
