Carboniferous Basins of Southwestern Missouri (Carboniferous of the United States)
Where: Missouri (37.1° N, 94.6° W: paleocoordinates 14.4° S, 39.1° W)
• coordinate based on political unit
When: Mississippian (358.9 - 323.2 Ma)
• 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.
• Plant materials come from light ash-colored somewhat arenaceous shales with minute particles of mica. Portions are massive, sandy and darker. Black coaly shales.
Preservation: adpression, replaced with pyrite, replaced with other
Collection methods: Collection is from 14 boxes collected by Dr. WP Jenney fot eh USGS in the fall of 1889 during a study of lead and zinc deposits in Missouri.
