WebGarnets have a variable chemical composition, which makes them a bit unique. This family of gemstones is always a silicate (SiO₄) with two other elements. Thus, “pure” garnet is always XₙYₙ (SiO₄). The X and Y groups are used to determine the family of garnet the stones fall into. Garnet has a long history of use. WebNov 12, 2024 · The major-element chemical composition of garnet provides valuable petrogenetic information, particularly in metamorphic rocks. When facing detrital garnet, information about the bulk-rock composition and mineral paragenesis of the initial garnet-bearing host-rock is absent. This prevents the application of chemical thermo-barometric …
