Plagioclase: The mineral Plagioclase information and pictures
The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and 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 appropriately known as the plagioclase feldspar seriesPlagioclase Geology Wiki Fandom11/08/2018 Plagioclase The plagioclase group consists of albiteanortite series of feldspars With the 50% rule, all of the mineral members occuring between these two are not considered valid minerals by IMA Basically, 50% rule says that Na dominant plagioclase is now albite and Ca dominant is anorthite However, the old plagioclases names are still used in petrology for Feldspars all about the plagioclases and Kfeldspars
Plagioclase Feldspar Common Minerals
The plagioclase feldspar subgroup consists of a continuous mineral series that is arbitrarily subdivided into six mineral categories whose composition varies from being relatively pure sodium aluminum silicate (albite) to a relatively pure calcium aluminum silicate (anorthite)Plagioclase Mineral Group igneous rocks classified by composition,igneous rocks are classified according to their mineral content: mafic rocks are dominated by plagioclase and pyroxene (even if you can't see them with the within these four groups, rocks are named depending on whether they display anorthite mineral group,plagioclase is an abundant mineral in the Plagioclase Mineral Group leafinancefrGroup name for Na, Ca feldspars IMA Status: Not Approved IMA : Locality: Common world wide occurrences Link to Location Data Name Origin: From the Greek plagios "oblique" and klao "I cleave" in allusion to the obtuse cleavage angles of the good cleavages Name Pronunciation: Plagioclase + Pronunciation : Plagioclase Image: Images:Plagioclase Mineral Data

Alternate name for the plagioclase series of feldspars In petrology, the plagioclase series are defined based on their percentage of albite (Ab) to anorthite (An) Compositions of individual samples are usually written as An24Ab76 meaning in this case that it is 24% anorthite and 76% albite List of plagioclase group members as used in petrologyLa fraction molaire d'albite dans le plagioclase peut être déterminée grâce à l'utilisation de méthodes puissantes, telle que la microsonde dont nous reparlerons ou à des méthodes optiques plus simples (méthode de Michel Minéralogie Les feldspaths plagioclasesThe feldspar group is a fairly large group with nearly 20 members recognized, but only nine are well known and common Those few, however, make up the greatest percentage of minerals found in the Earth's crust The following are THE FELDSPAR GROUP OF MINERALS
