    Orthoclase feldspar: Unlike plagioclase, orthoclase does not have striations across its cleavage plane. Cleavage faces will appear smooth. Orthoclase also typically has a colour range between white and pink, which is different than that of plagioclase. Feldspars which are in this grouping include: Microcline; Sanidine; Orthoclase; Orthoclase Crystals. Goodsprings, Nevada. University of

  • Feldspar IntroductionFeldspar - an overview

    In a significant proportion of feldspar ores, Na-feldspar (albite, NaAlSi3O8) and K-feldspar (KA1Si3O8 microcline or orthoclase) exist in the same matrix. The basic feldspar structure consists of a ring of four tetrahedral unit; Potassium and sodium feldspar have three silicon tetrahedral and one aluminium tetrahedron, while in calcium feldspar half of four tetrahedral unit are silicon- based

  • Feldspars in Weathering | SpringerLink

    Feldspar weathering occurs via dissolution of all components into solution, with the subsequent precipitation of secondary minerals from solution, and it is the feldspars dissolution rate which controls the overall rate of feldspar weathering. The rate of feldspar dissolution is controlled by the kinetics of surface reactions at the mineral-water interface, not by mass transfer processes

  • Orthoklas – Wikipedia

    Orthoklas, synonym auch als Adular oder Adularia bekannt, ist ein häufig vorkommendes Mineral aus der Gruppe der Alkalifeldspate innerhalb der Mineralienklasse der „Silikate und Germanate". Es kristallisiert im monoklinen Kristallsystem mit der chemischen Zusammensetzung K[AlSi 3 O 8] und ist damit chemisch gesehen ein Kalium-Aluminium-Silikat.

  • Orthoclase - Healing Stones, Healing Crystals

    A typical orthoclase is a solid solution of KAlSi3O8 and albite NaAlSi3O8. The origin of its name is probably from the Greek name for "right cleave", since the two cleavage planes of this stone are perpendicular to each other. Also known as alcali feldspar, this mineral is considered to be an igneous rock, very often found alongside granite.
