The X-site is 8 coordinated the Y -site is 6-coordinated octahedral and the Z-site is 4-coordinated tetrahedral.

Chemical formula of garnet. Oxygen 3836 O. Garnet The garnet group is composed of minerals of the general formula X 3 Y 2 Z 3 O 12 where X Mg Fe 2 or Ca. Can be Al Fe 3 Mn 3 V 3 or Cr 3.

Garnets have the general chemical formula A3B2Si3O12 where A is a divalent cation Fe2 Ca2 Mg2 Mn2 and B is a trivalent cation Fe3 Al3 Cr3. The generic formula for the common Garnets is. 16042018 Garnet Physical and Chemical Properties.

These minerals share a common crystal structure and a generalized chemical composition of X 3 Y 2 SiO 4 3. All species of garnets possess similar physical properties and crystal forms but differ in chemical composition. In that composition X.

B Al Cr Fe 3 Mn 3 Si Ti V Zr. X 2 3 Y 3 2 Si 3 O 12 X represents Ca Fe 2 Mn or Mg Y represents Al Cr or Fe 3 A more comprehensive list can be found in The chemical formula of Garnet. Chromium 2078 Cr 2717 CrO.

And Z Si. In addition to tetrahedral and octahedral sites such as those seen in spinels garnets have dodecahedral 12-coordinated sites. Garnet is a rather complex mineral that has a general chemical formula of R 3 R 2 SiO 4 3 where R 3 is a bivalent gives up two electrons metal and R 2 is a trivalent gives up three electrons metal when forming a chemical bond.

The most normally encountered minerals in the garnet institution consist of almandine pyrope spessartine andradite grossular and uvarovite. They all have a vitreous luster a obvious-to-translucent diaphaneity a brittle tenacity and a. Garnet is not a single mineral but describes a group of several closely related minerals.

All species of garnets possess similar physical properties and crystal forms but differ in chemical composition. The Garnet Group is composed of several minerals with related chemical formulas. This alters the expanded chemical formula of the Garnet.

The different species are pyrope almandine spessartine grossular varieties of which are hessonite or cinnamon-stone and tsavorite uvarovite and andradite. The general chemical formula is X 3 Y 2 SiO 4 3 where X cations are mostly Fe 2 Mn 2 Mg. Y Al Cr or Fe 3.

Calcium 2402 Ca 3361 CaO. Can be Ca Mg Fe 2 or Mn 2 and Y. Garnet is the name used for a large group of rock-forming minerals.

The simple chemical formula of the group is. X 2 3 Y 3 2 Si 3 O 12 X most often represents Ca Fe 2 Mn or Mg Y most often represents Al Cr or Fe 3 Some rarer varieties of Garnets called Hydrogarnets or Hydrogrossular contain some hydroxyl OH replacing some silica Si 3 O 12 or a reduced empirical formula of SiO 4. These minerals share similar crystal structure but they have a variable chemical composition.

The metal R 3 may be Calcium Ca Magnesium Mg ferrous Iron Fe or Manganese Mn and the metal R 2 may be Aluminum Al ferric. Garnet is actually a mineral group not a single mineral. 12122016 Garnet is the name used for a large group of rock-forming minerals.

Garnets are nesosilicates having the general formula X3Y2SiO43. Silicon 1684 Si 3602 SiO 2. Molecular Weight 50048 gm.
