过去对硫化矿床氧化带的次生富集矿物及钒类矿物研究较多,对砷酸盐矿物研究较少,尤其对氧化铜矿石和褐铁矿石中的砷赋存状态研究更少。经过几年的努力,我们在住北矽卡岩锡矿床氧化带中共发现16种砷酸盐矿物,其中一种定名为德保石(待审批的新矿物);一种是有疑义的矿物——硅砷铜石(?);其余为:光线石[Cu_3(AsO_4)(OH)_3]、橄榄铜矿[Cu_2(AsO_4)(OH)]、墨绿砷铜石[Cu_5(AsO_4)_2(OH)_4H_2O]、羟砷铜石[Cu_5(AsO_4)_2(OH)_4H_2O]、砷钙铜石[CaCu(AsO_4)
In the past, there were many studies on secondary enrichment minerals and vanadium minerals in the oxidation zone of sulphide ore deposits, and few studies on arsenate minerals, especially less studies on the occurrence of arsenic in copper oxide ore and limonite ore. After several years of hard work, we found a total of 16 arsenate minerals in the Oxidation Zone of the North Skarnite-Tin Deposit, one of which is named as Deborah (a new mineral subject to approval) and the other is a mineral of doubt - (AsO4) (OH) 3], olive copper [Cu2 (AsO4) (OH)], Cu5 (AsO4) 2 (OH) _4H_2O], Cu_5 (AsO_4) _2 (OH) _4H_2O], CaCu (AsO_4)
