Augite and Adamite Information

Minerals are solid substances, occurring naturally. Minerals are not organic compounds as their origins are inorganic. Interestingly, the process of formation of minerals do result from organic processes. The way in which the minerals are formed affects the Augite and Adamite. The appearance of a mineral is greatly influenced during its formation. Augite and Adamite information will help you understand how these minerals are found in nature. Here you can know all about it. Augite mineral belongs to Inosilicate and Adamite belongs to Arsenate minerals. It is also important to know the IMA status of a mineral, for the first mineral IMA status is Valid Species (Pre-IMA) 1792 and for second mineral it is Valid Species (Pre-IMA) 1866. Another important aspect is the minerals strength or hardness, Augite has Mohs Hardness between 5-6.5 while Adamite has a hardness of 3.5.
