vinyylipinnoite

Vinyylipinnoite is a rare mineral species, first discovered in 1995. It is named after its chemical composition, which includes vinyl groups and pinene, a type of terpene. The mineral is found in igneous rocks, specifically in granites and granodiorites, where it forms as a result of the alteration of primary minerals.

Vinyylipinnoite has a chemical formula of (C10H14)2O2. It is a member of the pinene group of minerals, which are characterized by their terpene structure. The mineral is typically colorless or white, but can also occur in shades of yellow or brown due to impurities. It has a vitreous to pearly luster and a white streak.

The crystal system of vinyylipinnoite is orthorhombic, and it forms in the form of short, prismatic crystals. It has a hardness of 2.5 to 3 on the Mohs scale and a specific gravity of approximately 1.1. The mineral is not commonly found, and its occurrence is limited to a few locations worldwide, including Finland, where it was first discovered.

Vinyylipinnoite is of interest to mineralogists due to its unique chemical composition and the rarity of its occurrence. It is not considered to be of significant economic value, but its study contributes to the understanding of the formation and alteration processes in igneous rocks. The mineral is classified under the International Mineralogical Association (IMA) as a valid species, with the approval number 1995-081.
