Interesting Facts about Minerals. Scientists who study minerals are called mineralogists. Around 99% of the minerals in the Earth's crust are made up of eight elements including oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.

It is currently not possible to have a "complete list of minerals". The International Mineralogical Association (IMA) is the international group that recognises new minerals and new mineral names. However, minerals discovered before 1959 did not go through the official naming procedure.

Minerals are elements or compounds that occur naturally in the Earth's crust. Rocks are mixtures formed of minerals. Just as elements are the building blocks of minerals, so minerals .

Granite is a common rock type and serves as a great example of sand forming processes. Granite is composed of feldspar (pink and white) which decomposes chemically into clay minerals. Another important constituent of granite is quartz (gray).

Minerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.

Chapter 2 THE CHARACTERISTICS OF SOILFORMING MINERALS AND ROCKS In order to clearly appreciate the problems of soil genesis some knowledge of rocks and rockforming minerals is necessary because, whether under arctic, temper ate or tropical conditions, all soils are derived either directly or indirectly from rocks and, hence, from rockforming minerals.

Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals. Clastic rocks are composed largely of quartz, feldspar, rock (lithic) fragments, clay minerals, and mica; any type of mineral may be present, but they in general represent the minerals that exist locally.. Clastic sedimentary rocks, are subdivided according to the dominant particle size.
