WebThe rock-forming garnets are most common in metamorphic rocks. A few occur in igneous rocks, especially granites and granitic pegmatites. Garnets derived from such rocks occur sporadically in clastic sediments and sedimentary rocks. Typical occurrences of the common rock-forming garnets are given in the Table. Garnets commonly contain many …
WebHowever, no actual garnet has a 100% pure chemical composition. Garnet gemstones are mixtures or blends, containing the chemistry of two or more garnet species. How Do Garnets Form? Regardless of the chemistry, all of the garnet group minerals form under similar geological conditions. Most of the time, garnet crystals form in metamorphic rocks. WebSpessartine is named after the Spessart Mountains, in Bavaria, Germany, which is the type locality for this mineral. Chemical Formula. Mn3Al2Si3O12. Composition. Manganese aluminum silicate.

Garnet sand is also used for water filtration media. As an abrasive, garnet can be broadly divided into two categories; blasting grade and water jet grade. The garnet, as it is mined and collected, is crushed to finer grains; all pieces which are larger than 60 mesh (250 micrometers) are normally used for sand blasting.
