Both K-spar and plagioclase are completely replaced by sericite, some of which has a greenish cast. Biotite, chloritized in alteration assemblages outward from here, is here both chloritized and sericitized. Quartz + pyrite + chalcopyrite + trace molybdenite veinlets common, and sulfides are also disseminated, especially in former feldspar sites.
