Title A name given to the resource BH250-6 Subject The topic of the resource Breccia Description An account of the resource Major Mineral: muscovite, biotite, pyrite, anorthite, quartz Texture Note: evidence of fluids through veins and depositing minerals such as calcite, sulfide BH250-6 is a breccia composed of angular rock fragments containing muscovite, biotite, anorthite and quartz. Numerous veins record the movement of mineral-rich fluids through fractures after brecciation. As the fluids cooled or reacted with the surrounding rock, they deposited calcite and sulfide minerals, including pyrite, along the veins and in open spaces.
