Minerals in diabase

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.

Web17 jul. 2024 · 1 Answer Sorted by: 2 Diabase is indeed relatively erosion resistant. One of the reasons is grain size. Consider the two other chemical equivalent of diabase: gabbro (coarse-grained) and basalt (glassy and fine-grained), which should potentially be similarly erosion resistant. This is not the case. Both gabbro and basalt erode very easily. WebA diabase dike is in close proximity to the silicified dolostone and may have provided the conduit for fluids during alteration.
