3.5: Types of Rocks
Figure 2. Granite is made of four minerals, all visible to the naked eye: feldspar (white), quartz (translucent), hornblende (black), and biotite (black, platy). Igneous rocks make up most of the rocks on Earth. Most igneous rocks are buried below the surface and covered with sedimentary rock, or are buried beneath the ocean water.

Feldspar
Notes. Theoretically speaking, the term 'feldspar' refers to a family of minerals with a specific crystalline presence. However actual feldspar powders are made from crushed crystalline rock containing a mixture of aluminum silicates of sodium and potassium (with minor amounts of lithium or calcium). They normally contain 10-15% alkali (K 2 O, Na 2 …

The mineralogy of sandstones: feldspar grains
Feldspars are also common in metamorphic rocks. As such, feldspar is an important (usually subordinate) component of most terrigenous clastics, reflected in its inclusion in QFL classification schemes. The two major groups of feldspar are potassium feldspars and plagioclases. All have low relief in plain polarized light (similar to quartz).

Feldspar Distinctions, Characteristics, and Identification
The basic feldspar recipe is X(Al,Si) 4 O 8, where X stands for Na, K, or Ca. The exact composition of the various feldspar minerals depends on what elements balance the oxygen, which has two bonds to fill (remember H 2 O?). Silicon makes four chemical bonds with oxygen; that is, it's tetravalent.
