Welcome to my userpage. I'm User:ChamithN and I started editing Wikipedia in 2014. I mainly edit articles related to computer science and entertainment; however, I'd be glad to help if someone needs my assistance for articles outside of my comfort zone. I tend to make a lot of typos over the course of editing. So, if you come across any (even in my talk page comments), feel free to revert/fix them, and/or ask me for clarification. I believe in WP:BRD cycle; ergo, I'm always up for civil and meaningful discussions. If you have any questions regarding editing Wikipedia, feel free to ask at the Teahouse or my talk page.
Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is found in a variety of deposit types, and is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite. Sphalerite is an important ore of zinc, with around 95 percent of all primary zinc extracted from its ore. Due to its variable trace-element content, sphalerite is also an important source of several other metals such as cadmium, gallium, germanium and indium. The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix. This photograph was focus-stacked from 125 separate images.Photograph credit: Ivar Leidus
