Feldspar Identification of specific feldspars

2019-6-17 · Feldspar Identification of specific feldspars: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some plagioclase feldspars are not

Introduction to Feldspar * Feldspars are the most abundant minerals in the earth's crust. They constitute about 2/3rd of the igneous rocks. * They are a group of rock-forming tectosillicate minerals that make up 51% of the earth's crust. * The w

ORTHOCLASE (Potasium Aluminum Silicate)

Orthoclase is a polymorph of other minerals that share the same chemistry, but have different crystal structures. If positive identification between these minerals can not be made by field methods, then the specimen may simply be referred to as a potassium feldspar or K-spar.Plagioclase feldspars lack potassium, are light colored and are usually striated.

Quartz vs Granite Difference

So what's the difference between quartz and granite? Quartz is a component of granite, while granite is made up of quartz, feldspar and other minerals. Quartz has a fine-grained texture as opposed to granite's coarse-grained surface consistency. The pure form of quartz is colorless and translucent but it may also be various light colors.

University of Minnesota's Mineral Pages: Potassium

It is far more difficult to discriminate between the feldspar group s internal divisions to distinguish plagioclase minerals from potassium feldspars. The presence of fine parallel striations on some plagioclase cleavage surfaces is the best way to distinguish the two. Plagioclase:

2015-4-28 · The plagioclase feldspars represent the "continuous branch" of Bowen's Reaction Series, and form a complete series between anorthite (the pure calcium member), and albite (the sodium-rich variety).
