Skorpion, Broken Hill, Salmo – July 24

Carbonate replacement deposits are well known for their minerals. Some produce a lot of carbonate minerals (Bisbee), others produce arsenate minerals (Tsumeb, Ojuela) and a rarer type produces phosphate minerals. The Skorpion mine (Namibia), Salmo (Canada) and Broken Hill (Zambia) produce a series of zinc phosphates, including tarbuttite, parahopeite, hopeite, zincolibethenite, and spencerite. Accessory minerals in these deposits include hydroxylapatite, pyromorphite, hemimorphite, smithsonite, and churchite-(Y) as seen below:
