Object number: BOS3471A
DescriptionBlack slate quarried at Eureka Slate Quarry, El Dorado County, California. A whole-rock chemical analysis of this specimen is included in USGS Bull. 275 Slate Deposits and Slate Industry of the United States by T. Nelson Dale with sections by E. C. Eckel W. F. Hillebrand, and A. T. Coons. Page 57 by W. T. Shaler. I'm not sure if the analysis was done on this exact specimen, or another of its type.
