What should be the content of a residual soil that formed in a humid climate from granite composed of quartz feldspar and black mica?
Small rock particles with a lot of clay.
What does Granite feel like?
Granite feels smooth and its color is black and brown. Really hard In it's natural state, it can be smooth if a stream runs over it, but it is often rough and flecked with mica, quartz, and feldspar. It's color is primarily gray with black spots, and, seen from a great distance, can appear to be snow.
What is the characteristics of granite?
Granite is coarse grained, has a uniformly dispersed crystalline structure, has a specific gravity of 2.6-2.7, is composed of varying amounts of various feldspars, quartz, micas, and other minerals, even small amounts of uranium. Granite is hard, tough, and resistant to fracture because of the interlocking structure of the minerals within. Granite's colors are varied; pinks, reds, and gray are most common. Its porosity is negligible, between 0.3 to 4%. It's weather resistant, heat resistant and even chemical resistant.
How does granite look and feel?
A granite countertop of sufficient quality should look and feel as smooth as glass.
What are the colors and texture of both granite and basalt?
Granite and Basalt: 1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It contains the minerals feldspar, quartz and mica. Its mineral grains are similar in size. Granite is hard to scratch with a fingernail. 2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine. Like granite, basalt is hard to scratch with a fingernail.

What is the composition of granite?
Granite is defined as a course grained rock that must have plagioclase feldspar, potassium (aka alkali) feldspar, and quartz. Granite can also have a number of secondary minerals like micas or hornblende, but these secondary minerals do not have to be present.
What are the pink spots found on a rock?
If the rock is granite, the pink spots are probably feldspar. Look for colorless spots and black shiny flaky spots, these will be quartz and mica, which are the other components of granite. Pink spots on a flaky, shiny, micacaeous grey or black rock might be garnets in mica schist.

What is pink granits minerals?
The pink part is probably orthoclase feldspar, the gray stuff is quartz, the small white stuff could be monocline feldspar, the shiny black or brown specks could be mica or hornblende.
What 3 minerals do most granitic rocks contain?
Feldspar (the pink one), Quartz (the white one), Biotite (also possibly hornblende) <- the black one
What is the mineral classification of quartz?
The group of rocks that usually have the mineral quartz as part of their composition is the granitic group. Quartz is one of the last minerals to crystallize filling in the gaps in granite as it cools.
What are the chemical formula for diorite?
Diorite does not have a chemical formula. Chemical formula are for compounds. Diorite is a mixture of several compounds. The coposition of diorite is variable, so there is no chemical formula that could describe it.
Is there such a thing as black granite?
yes there is such a thing as black granite
