تعريف plajiyoklas في التركية الإنجليزية القاموس.
- (Jeoloji) plagioclase
- (Kimya) A form of feldspar consisting of aluminosilicates of sodium and/or calcium, common in igneous rocks and typically white
- A triclinic feldspar
- See the Note under Feldspar
- Any member of the series of abundant feldspar minerals that usually occur as light-to medium-grey-coloured, transparent to translucent grains or crystals. Plagioclase ranges in composition from albite to anorthite. It is used in the manufacture of glass and ceramics; iridescent varieties are valued as gemstones. The primary importance of plagioclase, however, derives from its role as a rock-forming mineral
- A member of the feldspar mineral family Plagioclase feldspars are silicates that contain considerable sodium and calcium Feldspar crystals are stubby prisms, generally white to gray and a glassy luster
- <)))
- A triclinic mineral with the general chemical composition of Al2Si2O8
- A general term used of any triclinic feldspar
- A group of feldspar minerals that form a solid solution series from albite (sodium aluminum silicate) to anorthite (calcium aluminum silicate). The plagioclase feldspars are found in igneous, plutonic, and metamorphic rocks. They all have the triclinic-pinacoidal crystal habit, but only Albite commonly occurs in well crystallized specimens
- any of a rock-forming series of triclinic feldspars
