Caption:
Plagioclase-phyric andesite variably albitized, forming pseudoclasts subsequently fractured, infilled and replaced by K-feldspar and magnetite (drill hole EH691, Ernest Henry deposit, Cloncurry district, Australia). Plagioclase phenocrysts are texturally preserved but albitized and K-feldspar altered. The pseudo breccia is brecciated, infilled and extensively replaced by a pyrite-chalcopyrite-magnetite assemblage.
