Chlorite and its Relationship to Pyritization in Anoxic Marine Environments

Roy H. Grossman, Richard S. Liebling, Horst S. Scherp

ABSTRACT

Pyritiferous basal marine shales of the early mid-Devonian Hamilton Group of New York State display an inverse relationship between pyrite abundance, as a proportion of the chlorite present, and the iron content of the chlorite. This relationship suggests that chlorite was a significant source of iron during pyritization. The data also suggest that chlorite was broadly segregated into an iron-rich fraction, occuring nearer the source, and one of lower iron content, found farther west.
