All of the Metallic ores such as Magnetite, Pyrite, Bauxite, Hematite etc. can be called Metallic Minerals. Non-Metallic Minerals: These Minerals do not contain any metals, so they generally have Non-Metallic physical properties. Though we cannot extract metals from these Minerals, Non-Metallic Minerals are still of immense use to humankind.

Propylitic alteration is a type of hydrothermal alteration that occurs in volcanic and plutonic rocks. It is characterized by the alteration of primary minerals, such as feldspar and quartz, to secondary minerals, such as chlorite, epidote, and sericite. Propylitic alteration typically occurs at lower temperatures (less than 200°C) and involves the …
