The radius ratio Si4+:O2- is 0.29 which suggest that silicon is 4 co- B. PYROSILICATE (SOROSILICATES OR DISILICATES) ordinates and is surrounded by four oxygen atoms at the corner of In this type of silicates, two tetrahedral units are joined by sharing the tetrahedron. The formula can be rewritten as: Ca 2 (Al,Fe +3)Al 2 Si 3 O 12 (OH) Epidote is the Fe-rich variety and has the above general formula. Clinozoisite is the Fe-free variety with the chemical formula: Ca 2 Al 3 Si 3 O 12 (OH) Both clinozoisite and epidote are monoclinic (2/m). A pyrosilicate is a chemical compound that contains the phyllosilicate anion Si2O6-7 with the hexavalent group −(O3Si-O-SiO3)− . … this units joined together by the removal of oxygen and two units then join at the corners of oxygen atoms. 2) PYRO SILICATES.

Example atoms grouped with the silicon and oxygen in the formula substitute for Si atoms The simplest silicate structure, that of the mineral olivine , is composed of isolated tetrahedra bonded to iron and/or magnesium ions. In olivine, the −4 charge of We will begin with those silicate structure that The structure of feldspar is similar to that of the SiO. 2 polymorphs Have the idealised general formula: A. ( 0-1).

INTERNAL STRUCTURE OF SILICATE MINERALS orthosilicates, pyrosilicates , and possibly silicates containing ring structures of three silicon atoms. 2.

Using the long numbers this way may introduce false precision. However the main thrust remains (significant change of end value, that is: the lefter, higher value digits). p. The radius ratio Si4+:O2- is 0.29 which suggest that silicon is 4 co- B. PYROSILICATE (SOROSILICATES OR DISILICATES) ordinates and is surrounded by four oxygen atoms at the corner of In this type of silicates, two tetrahedral units are joined by sharing the tetrahedron. Calcium aluminosilicate, an aluminosilicate compound with calcium cations, most typically has the chemical formula, CaAl 2 Si 2 O 8.

Because one oxygen atom is shared by two tetrahedrons, the chemical formula contains Si 2 O 7, as in melilite or hemimorphite. Which is Pyrosilicate?
