Zinclipscombite is a dark-green to brown zinc iron phosphate mineral with the formula Zn(Fe3+)2(PO4)2(OH)2.[2][3] It occurs as fibrous spheres and exhibits tetragonal crystal structure.[2]
In the classification of non-silicate minerals zinclipscombite is in the lipscombite group, which also includes lipscombite.
Discovery[]
The mineral zinclipscombite was discovered and named by Chukanov, Pekov, Möckel, Zadov, and Dubinchuk [4][5] from a sample from the Silver Coin mine, , Valmy, Humboldt County, Nevada, United States. The new mineral name was approved in 2006 by the Commission on New Minerals and Mineral Names, International Mineralogical Association.
