The stratigraphic relationships of the units underlying the Ohio Shale in the Bellefontaine Outlier to the strata beneath the Ohio Shale in central Ohio, 46 km east, have remained problematic since the initial report on the geology of Logan County in 1878. Recent publications by the Ohio Geological Survey convey the general working view that many geologists have used for the outlier; the ...The pyritic black shale facies is interpreted as being deposited in a brackish water, coastal marsh or swamp environment. Historically, the pyritic shale facies would be interpreted as part of the “outside shale” in the cyclothem model (Heckel, 1977). May 12, 2022 · It is a fissile, fine-grained, clastic sedimentary rock comprised of microscopic (less than 1/256 mm in size) mineral particles and phyllosilicate (clay) minerals that were deposited in very low-energy and often relatively anoxic (oxygen-poor) environments, such as deep lakes, ocean basins, and swamps. ... pyritic ash pulp densities 10 ...
