Environment/lithology: marginal marine; black shale

• "Fagerstrom (1967), based on local stratigraphy, the lithology, and the poor preservation of the marine organisms, considered the H.Q.Shale to represent an estuarine environment, a 'small, stagnant embayment occyping a previously eroded channel.' BA 1(?) or nonmarine."

•SEP environmental call basd on given information
