Zinc makes about 2000 of 1 percent of the earths crust, making in the 25th most common element. But it is never found as a native metal but there are a number of important zinc minerals such as sphalerite (which is zinc sulphide), smithsonite (zinc carbonate, ZnCO3), zincspar (also is zinc carbonate, ZnCO3), and marmatite (zinc sulphide, ZnS, containing some iron sulphide, FeS). The sphalerite (which also is known as zinc blende and black jack) is the most abundant and important zinc minerals, so today I am going to talk about sphalerite. Here are some pictures for the sphalerite.
Sphalerite is found in the veins that were formed above molten igneous rocks. Like the top of a magma chamber. Sphalerite is a crystal and soft scratched mineral...
