GROSSULAR GARNETS, QUARTZ, HEMATITE (miniature)
Grossular is a calcium-aluminium member of the garnet mineral group, characterized by the chemical formula Ca3Al2(SiO4)3. In its composition, calcium can be partially substituted by ferrous iron, while aluminium may be replaced by ferric iron. The name grossular is derived from the gooseberry, grossularia, reflecting the green variety of this garnet found in Siberia. It also appears in other colors, including cinnamon brown, red, and yellow, and is recognized as a gemstone.
In geological contexts, grossular has frequently been referred to as grossularite. However, since 1971, the International Mineralogical Association has advised against the use of the term grossularite for this mineral.
This specimen has at least three other minerals present including quartz, haematite. Definitely some specimen for micro mounts.
Hematite, alternatively spelled haematite, is a prevalent iron oxide compound represented by the formula Fe2O3, commonly occurring in various rocks and soils. The crystals of hematite are classified within the rhombohedral lattice system, identified as the alpha polymorph of Fe2O3.
