Lithology and environment
| Primary lithology: | ferruginous,black,gray,green silty,calcareous claystone |
| Includes fossils? | Y |
| Lithology description: "green-gray claystone", but described by Marsh as blue and by Wieland as black. Lull 1919 analysis: "The rock consists of clay with the very finest silt, the grains of which are probably not more than .01 mm in diameter. A fine grit was discernible in the clay, and an appreciable content of lime, as shown by a vigorous effervescence with acid. The gray clay shows occasional rusty stains from recent weathering, probably due to the presence of ferrous carbonate." | |
