Widely used types of minerals are gems ores precious stones etc. However these mineral types lack solid definition and they are often mixture of various minerals with different chemical and physical properties. Scientists mostly use Strun classification based in mineral chemistry and crystalography.

A mineral with visible layers like Rhodochrosite has a banded habit. Amethyst has a drusy habit where jagged projectiles line a rocks interior. Close observation and perhaps a magnifying glass are all you need for this step in the mineral identification process.

The chemical name for the substance of quart is silica and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks silica is called an acid in silicates the substances other than silica are called bases for example lime potash and soda. When giving the full name of a silicate the names of these bases

Lithium. Lithium is an element valuable for the production of glass aluminum products and batteries. It is mined from ores of petalite LiAlSi 2 O 5 2 lepidolite KLiAl 3 AlSiRb 4 O 10 FOH 2 spodumene LiAlSiO 3 2 and also subsurface brines. Australia and Chile are the worlds largest producers of lithium.

In another common method of classification ore minerals are divided into hypogene also termed primary deposits and supergene also known as secondary deposits. The secondary deposits are formed as alteration products of primary deposits through weathering and related processes. An ore deposit may be either of igneous or of sedimentary origin.

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host or are related to REE ores are carbonatite and phoscorite igneous rocks composed principally of

The first genetic classification of ore deposits to win wide acceptance was that initially proposed by Waldemar Lindgren in 1906 and last revised by him in 1933. As ideas on the genesis of ores have undergone change in the thinking of geologists the Lindgren classification has come under attack mainly by two groups.
