Batu limestone atau batu kapur mengandung sebagian besar mineral kalium karbonat. Totalnya bisa mencapai 95% yang diubah menjadi oksida dengan kalsinasi. Dengan cara ini maka limestone lebih mudah dimurnikan untuk memperoleh kalsiumnya. Karenanya, batu kapur bukan hanya dipakai untuk konstruksi namun juga untuk bidang lainnya. In short, rocks are made up of a variety of different materials, including some minerals. The amount of mineral that’s in a rock will vary depending on what rock you’re looking at.

Metasomatism (from the Greek μετά metá "change" and σῶμα sôma "body") is the chemical alteration of a rock by hydrothermal and other fluids. [1] It is the replacement of one rock by another of different mineralogical and chemical composition. The minerals which compose the rocks are dissolved and new mineral formations ...

It is useful for dating very old igneous and metamorphic rocks and also meteorites and other cosmic fragments. However, there is a limited range in Sm-Nd isotopes in many igneous rocks, although metamorphic rocks that contain the mineral garnet are useful as this mineral has a large range in Sm-Nd isotopes.Galena is a lead sulfide mineral with a chemical composition of PbS.
