Emilite and Enargite 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 Emilite and Enargite. The appearance of a mineral is greatly influenced during its formation. Emilite and Enargite information will help you understand how these minerals are found in nature. Here you can know all about it. Emilite mineral belongs to Not Available and Enargite belongs to Sulfide mineral. It is also important to know the IMA status of a mineral, for the first mineral IMA status is Approved IMA 2002 (Dana # Added) and for second mineral it is Valid Species (Pre-IMA) 1850. Another important aspect is the minerals strength or hardness, Emilite has Mohs Hardness between 3.5-4 while Enargite has a hardness of 3.
