Kaheahelaline

Kaheahelaline is a rare and distinctive mineral species discovered in 2016. It is named after the Kaheahele lava flow in Hawaii, where it was first found. Kaheahelaline is a member of the zeolite group, characterized by its complex crystal structure and unique chemical composition. The mineral is typically colorless or white, with a vitreous luster, and exhibits a perfect cleavage in one direction.

Kaheahelaline forms in volcanic environments, specifically in the cavities of basaltic lava flows. Its formation is closely associated with the alteration of volcanic glass and the presence of alkaline fluids. The mineral is often found in association with other zeolites, such as chabazite and phillipsite, as well as with other secondary minerals like calcite and gypsum.

The chemical formula of kaheahelaline is (Na,K)4-5[Al6Si10O32]·nH2O, indicating its sodium and potassium content, along with aluminum and silicon in its framework structure. The mineral's stability and formation are influenced by factors such as temperature, pressure, and the availability of specific elements in the host rock.

Kaheahelaline is of interest to mineralogists and geologists due to its rarity and the unique conditions under which it forms. Its discovery has contributed to the understanding of zeolite mineralization in volcanic environments and the processes involved in the alteration of volcanic glass. The mineral's distinctive properties and occurrence make it a valuable subject for further study and potential applications in materials science and geochemistry.
