Mohs scale of mineral hardness - Simple English

2021-4-24  Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.

Plagioclase Feldspar: A group of common rock

What is Plagioclase? "Plagioclase" is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8).Minerals in this series are a homogenous mixture of albite and anorthite. The names of the minerals in the series are arbitrarily given based upon their relative abundance of albite and anorthite.
