Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ilmenite (2%). Accessory and alteration minerals include hornblende, biotite, apatite, pyrrhotite, chalcopyrite, serpentine, chlorite, and calcite. The texture is termed d… WebAs mentioned, diabase consists of plagioclase feldspar and pyroxene. These minerals make up between 60 and 75 percent of the rock. The remaining 25 to 40 percent is made …
