贵州滥木厂铊矿床中斜硫砷汞铊矿出溶结构的发现及其意义

THE DISCOVERY OF EXSOLUTION TEXTURE ON CHRISTITE IN LANMUCHANG THALLIUM ORE DEPOSIT AND ITS SIGNIFICANCE

报道了贵州滥木厂铊矿床产出的斜硫砷汞铊矿的出溶结构，对其特征进行了较详细地描述，并初步探讨了其成因和发现意义。

The exsolution texture on christite is first reported in Lanmuchang thallium ore deposit,Xingren county,Guizhou province.Under the electron microprobe the christite occurs as leaf in the cinnabar,associated with barite,kaolite,pyrite,marcacite and some unknown thallium minerals.The leaves are arranged in the order of size ranging form 0.001×0.004 to 0.008×÷0.022 mm;their electron images are very clearm,conforming with X ray face distribution distribution images of thallium and arsenic.On the basis of these data,the authors study the genesis of the exsolution texture on christite and its significance.The exsolition texture is considered to indicate that cinnabar and christite aer formed simultaneously.
