Pimelite is the name of a mineral of the pyroxene group. It has a green color and is commonly found in igneous rocks. There are several synonyms for the word pimelite, including green augite, green diopside, and green omphacite. These terms describe different variations of the mineral based on their chemical composition and crystal structure. Green augite is typically found in volcanic rocks, while green diopside is found in metamorphic rocks. Green omphacite is a type of jadeite, found in high-pressure and low-temperature metamorphic rocks. Regardless of the various synonyms used to describe pimelite, the mineral remains a valuable resource for geological research and industrial purposes.
