Granite contains plagioclase feldspar and potassium feldspar. It really depends on the composition of the magma from which it forms. If the granite has a lot of pink in it, chances are it is potassium feldspar (K-Spar). If it is dominated by white, then the feldspar is probably plag.

Pink crystals found in granite are called?
FELDSPARS
Two mineral grains that are found in soil and formed from granite?
Quartz and mica. Clay minerals come from decomposing feldspars.
Does granite interlock?
Granite is composed of interlocking mineral crystals of quartz, micas, and feldspars mainly.
Why does granite have speckles in it?
The dark speckles in granite are biotite and hornblende set against a background of lighter minerals, primarily quartz and alkali feldspars.
Does granite have large mineral grains?
Granite is formed from magma that cools slowly, deep below the earth's surface. Very coarse-grained granite, called pegmatite, is formed when the magma cools extremely slowly. Most granite is hard grained

What is the definition of granite?
a pink-colored, felsic, plutonic rock that contains potassium and usually sodium feldspars and has a quartz content of about 10%. Granite is found on continents but virtually absent from ocean basins.
Why does granite have speckles in it?
The dark speckles in granite are biotite and hornblende set against a background of lighter minerals, primarily quartz and alkali feldspars.
What minerals are commonly present in granite?
Quartz, Feldspar (or Felspar) and Mica. Other minerals may be present but all of the above three must be therefor a Granite.
Is a granite a rock or a mineral?
Granite is an igneous rock. It is commonly formed from the following minerals. Quartz, potassium and Plagioclase Feldspars and Biotite Mica.
What is the chemical composition for pink granite?
Pink granite would consist primarily of potassium feldspar and quartz with minor amounts of mica and other feldspars.
Quartz is an example of what type of rock?
Quartz and feldspars are the most common minerals found in continental crustal rocks.
What physical properties distinguish plagioclase feldspars from orthoclase feldspars?
One physical property that distinguishes plagioclase feldspars from orthoclase feldspars is their cleavage. Plagioclase feldspars typically exhibit good cleavage in two directions at right angles, while orthoclase feldspars show perfect cleavage in one direction. Another distinguishing feature is their color. Plagioclase feldspars are usually white to gray, while orthoclase feldspars can be white, pink, or other colors.
Are granite found in Jamaica?
where in Jamaica is granite found
What is granite rock explain?
Granite is an igenous rock that was formed via solidification of a magma several kilometers deep in the crust. Granite is mineralogically defined a s a rock that has a quarz/feldspar ratio of 0.2 to 0.6, and has a ratio of alkali feldspars vs plagioclase of 1/3 to 0.9. Furthermore Quarz and feldspars must make up more than 10 % of the minerals of the rock and it may not have been deformed to become a metamorphic rock (gneiss). Chemically granite is defined as the igneous rock type richest in silicon.
