Solution Orthoclase Mineral kpjlangeveen

Orthoclase as a Feldspar Mineral. Orthoclase is a member of the alkali feldspar series. The alkali feldspars include albite (NaAlSi 3 O 8), anorthoclase ((Na,K)AlSi 3 O 8), sanidine ((K,Na)AlSi 3 O 8), orthoclase (KAlSi 3 O 8), and microcline (KAlSi 3 O 8). These feldspar minerals form a solid solution series between NaAlSi 3 O 8 and KAlSi 3 O 8.

Orthoclase: Mineral information, data and localities.

Named "orthose" in 1801 by Rene Just Haüy from the Greek orthos "right" in allusion to the mineral's right angle of good cleavage. The sense of Haüy's name was that the mineral was a feldspar, but he did not specify a type-locality, nor did Haüy give a chemical analysis.

Orthoclase: Pink granite, Mohs hardness and moonstone

UsesFormationGeologyChemistryNomenclatureDurabilityAppearanceOrthoclase has several commercial uses. It is a raw material used in the production of glass, ceramic tile, porcelain, dinnerware, bathroom fixtures, and other ceramics. It is used as an abrasive in scouring powders and polishing compounds. It is also cut as a gemstone. An adularescent gem material known as moonstone is an intergrowth of orthoclase and albite.

Plagioclase Feldspar: A group of common rock

What is Plagioclase? “Plagioclase” is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8).Minerals in this series are a homogenous mixture of albite and anorthite. The names of the minerals in the series are arbitrarily given based upon their relative abundance of albite and anorthite.

2020-9-8  Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture", in reference to its two cleavage angles).
