2019-09-05· Almost all rocks are made of minerals. The exceptions are obsidian (which is made of volcanic glass) and coal (which is made of organic carbon.) Learning the basics of mineral identification is easy. All you need are a few simple tools (like a magnet and a magnifying glass) and your own powers of careful observation.
There are various mineral types and classifications. 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 Strunz classification based in mineral chemistry and crystalography. Other very popular system is Dana ...

Minerals in the series can be a combination of both anchor members. Some mineral series, such as the Spinel series, contain more than two end members. This means there can be several different combinations of intermediary members. In a few complex mineral series, such as Garnet, more than one element may be replaced by another. A mineral series may contain a .

A mineral or placer claim has a set expiry date (the "Good To Date"), and in order to maintain the claim beyond that expiry date, the recorded holder (or an agent) must, on or before the expiry date, register either exploration and development work that was performed on the claim, or a payment instead of exploration and development. Failure to maintain a claim results in automatic ...
Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Common rocks include granite, basalt, limestone, and sandstone.
The Mohs scale is a set of 10 minerals whose hardness is known. The softest mineral, talc, has a Mohs scale rating of one. Diamond is the hardest mineral and has a rating of ten. Softer minerals can be scratched by harder minerals because the forces that hold the crystals together are weaker and can be broken by the harder mineral.

The following mining industries can be researched: gold, iron, copper, diamond, phosphate, coal, manganese, chromium or platinum group metals (PGMs). Learners could also choose their own. The projects need to be handed out in the beginning of the term/chapter.
Different groups of minerals break in different fashions, thus, showing different kinds of cleavage. Minerals that do not cleave are known to fracture. A mineral fractures when broken or crushed. Fractured surfaces in some minerals may exhibit a characteristic appearance which can help in identification. The types of mineral fractures include: Conchoidal: Leads to a series of .
