Quantifying early mineral weathering reactions in
Augite weathering rates were calculated for both the PHQF and PHVC-2 profiles (Table 2). Rates in both profiles were similar, although R augite in the PHQF profile is approximately two times slower than in the PHVC profile. This is most likely due to heterogeneity in the bedrock or differences in water infiltration due to fracture distribution.

Hornblende vs Augite: Differences And Uses For Each One
Augite is a member of the pyroxene group of minerals. The augite in this rock has undergone some degree of alteration, resulting in the formation of epidote. Augite is an important mineral in the formation of many igneous rocks. The augite in this rock is part of a larger mineral assemblage that includes hornblende and plagioclase.

Augite
Augite's beauty isn't always immediately visible. Typically dark green to black, its colors might go unnoticed at first glance. Look closer, and you may find hints of brown. The crystals are usually short, stubby prisms, which when well-formed, can be incredibly attractive. The lustre varies from vitreous – glassy, to dull.
