Microcline may be clear, white, pale-yellow, brick-red, or green; it is generally characterized by cross-hatch twinning that forms as a result of the transformation of monoclinic orthoclase into triclinic microcline. Introduction to the Meaning and Uses of Charoite. Optical Properties : Microcline s tartan plaid twinning (a combination of albite and pericline twinning) is its most diagnostic. Most microline is formed at high temperatures during crystallization of magma or by deep metamorphism. Microcline may be chemically the same as monoclinic orthoclase, but because it belongs to the triclinic crystal system, the prism angle is slightly less than right angles; hence the name "microcline" from the Greek "small slope." Microcline is usually opaque to translucent, white to pale-yellow in color, and has a vitreous-to-dull luster. ... Microcline feldspar - a mineral species with chemical composition of KAlSi2O8. Has perfect cleavage parallel to {001} and good cleavage on {010}. The chemical compound name is potassium aluminium silicate, and it is known as E number reference E555. It is common in granite and pegmatites. Microcline forms during slow cooling of orthoclase; it is more stable at lower temperatures than orthoclase. Charoite is an incredible stone of the Violet Ray with an almost tangible movement of energy flowing in magnificent swirls and eddies of violet, lavender and purple. It stabilizes brain waves and brings clarity to our thoughts. Microcline is a potassium aluminum silicate.The name Microcline is derived from the Greek words micros, meaning small, and klino meaning lean, because the cleavage planes in microcline deviate very slightly from 90 degrees. Microcline is mined for use in the manufacture of glass and ceramics. METAPHYSICAL PROPERTIES, LORE, USES: Metaphysical practitioners believe that microcline stimulates clarity of thought, enhances general understanding, and improves one’s ability to cooperate with others. This page was last edited on 3 September 2020, at 19:20. Relief: Low negative Habit/Form: It is commonly found as anhedral and euhedral grains in many igneous and metamorphic rocks. In one direction, it has perfect cleavage, but in another direction, the cleavage is only good, thereby forming almost perfect right angled prisms. Microcline is believed to be a stone of understanding, cooperation, and clarity. The Spanish explorers who named it apparently confused it with another green mineral from that region. Microcline is a common mineral found worldwide, the massive form is green and green and cream striped (Albite) in colour. Microcline may be chemically the same as monoclinic orthoclase, but because it belongs to the triclinic crystal system, the prism angle is slightly less than right angles, hence the name “microcline” from the Greek “small slope.” It is a fully ordered triclinic modification of potassium feldspar and is … Amazonite is a mineral of limited occurrence and is present in parts of Brazil, Colorado and Virginia in the United States, Australia and Madagascar. The chemical compound name is potassium aluminium silicate, and it is known as E number reference E555. When viewed under a polarizing microscope, microcline exhibits a minute multiple twinning which forms a grating-like structure that is unmistakable. It can be difficult to see cleavage in thin section due to microcline's low relief. METAPHYSICAL PROPERTIES, LORE, USES: Metaphysical practitioners believe that microcline stimulates clarity of thought, enhances general understanding, and improves one’s ability to cooperate with others. Orthoclase is one of the most common minerals, and occurs in numerous mineral environments. It is a fully ordered triclinic modification of potassium feldspar and is dimorphous with orthoclase.
