What are the chemical formula for diorite?

Answer 1

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.

Answer 2

The chemical formula for diorite is generally described as (Ca,Na)2(Al,Fe)3(SiO4)3. It is a coarse-grained, intrusive igneous rock composed primarily of plagioclase feldspar, biotite, hornblende, and pyroxene minerals.

Answer 3

Diorite is an intrusive igneous rock mostly composed of plagioclase feldspar, biotite mica, hornblende, and/or pyroxene. It mostly appears as gray in color, or whitish with black specs--a salt and pepper look. It may contain small amounts of quartz.

Answer 4

A majority of quartz, then alkali feldspar, plagioclase feldspar, possibly some biotite mica and hornblende.

Answer 5

It is Made up of molten lava like an extrusive rock, which is formed beneath earths surface.

Answer 6

The chemical formula for regular rhyolite is...

Feldspar, quartz and biotite.

Answer 7

Diorite is composed mostly of plagioclase feldspar, biotite, hornblende, and pyroxene.

Answer 8

The minerals that make up Diorite are Hornblende, Mica, and White Feldspar

Answer 9

In many cases there are few minerals in tuff, as it is to a large degree composed of glass. Minerals that may be present include quartz, potassium feldspar, and albite.
