註釋The content and association of minor elements in different black-shale environments. Emission spectrographic analyses of 220 samples of black shale from Pennsylvanian rocks of the shelf area in the Eastern Interior coal province and from Ordovician and Silurian rocks of the western North America eugeosyncline have been compared. Some samples of both the shelf group and the eugeosynclinal group have high contents of vanadium, chromium, zinc, silver, and moderately high contents of nickel and copper. High molybdenum and nickel contents are characteristic of the samples from the shelf; high barium content is characteristic of the samples from the eugeosyncline.
