Detailed description, properties, locality information guide about the plagioclase feldspar mineral group: albite to andesine.
Plagioclase is a series of tectosilicate framework silicate minerals within the feldspar group. Rather than referring to a particular mineral with a specific
Hardness 6-6.5 and cleavage are good indicators of a plagioclase as opposed to other This rollover demonstrates extinction within the plagioclase mineral.
As this is a triclinic mineral, the indicatrix axes will not line up with the crystal axes Hardness and cleavage are good indicators of a plagioclase as opposed to
Plagioclase Labradorite. Comments: Dual view of a cleavage fragment of labradorite showing the multi-colored labradorescence schiller effect and the same
Plagioclase mineral data, information about Plagioclase, its properties and worldwide locations.
A petrological term for plagioclase series feldspars dominant in calcium. Note in pure mineralogical terms the name anorthite would cover all of this range.
In petrology, the plagioclase series are defined based on their percentage of albite Ab to anorthite An You should always treat mineral specimens with care.
Plagioclase Series of the Feldspar Group of Silicate Minerals Plagioclase feldspars are a continuous mineral series in which calcium and sodium substitute for
