我国华南地区砷酸盐矿物的初步研究

A Preliminary Study of Arsenate Minerals from South China

本文介绍了笔者近几年在华南地区发现的16种砷酸盐矿物的研究成果,其中,德保石(?)是待审批的新矿物,硅砷铜石(?)是有疑义的(新)矿物;而光线石、墨绿砷铜石、羟砷铜石、乳砷铅铜石、砷铅铁石、绿砷钡铁石及含钡毒铁石等是在国内首次发现的矿物;橄榄铜矿、砷铅石等在国内未见有其矿物学数据的公开报导。文章提供了这16种砷酸盐矿物的矿物学参数,并对该类矿物的形成条件进行了初步的探讨。

In recent years, the authors have found sixteen sorts of arsenate minerals in South China, which include dehaoite (?), copper silicarsenate (?), clinoclasite, olivenite, cornwallite, cornuhite, conichalcite, adamite, duftite, hayldonite, mimetesite, carminite, dussertite, scorodite, Ba-bearing pharmacosiderite and heudanite. The physical properties, optical constants, chemical composition, X-ray data, infrared absorption spectra and differential thermal analyses of the minerals are given in this paper, which serve as a sheet of fairly perfect data for arsenate minerals in China. Finally, the paper makes a preliminary discussion on the formation conditions of arsenate minerals.
