Duftite in calciteThe lovely green inclusions scattered in zones in the white calcite crystal are a complex hydrated lead copper arsenate )plus a dash of calcium and zinc, sometimes) mineral that formed when an anoxic primary ore deposit was altered by oxygen rich waters in the land now known as Namibia. Any mineral collector’s body hairs will stand up when the word Tsumeb is uttered, that fount of many mineral wonders in the middle of the Namibian desert (see http://on.fb.me/1c2CjkD for an account) . Duftite was named after the manager of this famed mine and is often found accompanying other rare and beautiful oxidation products. The usual colour is green, in varied shades and the lead content makes the mineral very dense in the hand. As well as Namibia, it is also found in Morocco, France, Germany, Russia, England, Mexico, the United States, and Australia.LozImage credit: fosagams.co.zahttp://www.mindat.org/loc-2428.htmlhttp://www.mindat.org/min-1325.htmlhttp://www.galleries.com/Duftitehttp://bit.ly/1bZmCvbhttp://bit.ly/1GzVWc2 -- source link
