Abstract
Preliminary data are reported for two supergene sulfides from northern Chile. One, apparently a cuprian sphalerite (nil to 15 ± 2 percent Cu.), formed as an intermediate stage in the replacement of sphalerite by djurleite. The second, with a composition close to Cu3ZnS4 was a product of the breakdown of the first phase during a subsequent oxidation episode.
