Vauquelinite and Vaughanite 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 Vauquelinite and Vaughanite. The appearance of a mineral is greatly influenced during its formation. Vauquelinite and Vaughanite information will help you understand how these minerals are found in nature. Here you can know all about it. Vauquelinite mineral belongs to Phosphate minerals and Vaughanite belongs to Not Available. It is also important to know the IMA status of a mineral, for the first mineral IMA status is Valid Species (Pre-IMA) 1818 and for second mineral it is Approved IMA 1989. Another important aspect is the minerals strength or hardness, Vauquelinite has Mohs Hardness between 2.5-3 while Vaughanite has a hardness of 3-3.5.
