Book Description
Excerpt from On Pyrite and Marcasite Sir: The subject of the secondary enrichment of ore bodies is one of the most important in chemical geology, and probably also one of the most complex, because nothing like chemical homogeneity is to be an tieipat'ed at or beneath the croppings of ore deposits. A long time must elapse before the processes involved are fairly clear. The memoir by D1. II. N. Stokes Which I transmit herewith, for publication in the Bulletin series, is 2111 important contribution to this subject, describing a method for the quantitative determination of pyrite and mareasite When in mixture, and discussing some of the relations of these most abundant sulphides to those of copper. This memoir represents only a portion of Dr. Stokes's work in this field, and it is to be expected that other papers will follow as soon as practicable.
