硒锑矿的某些新资料
SOME NEW DATA ON ANTIMONSELITE
【摘要】 硒锑矿是由我国首先于1993年发现的一种硒化物类新矿物。笔者稍后在湖南坌头碳硅泥岩型铀矿床中也检出了数量稍多,单体粒度约0.1~0.5mm和集合体粒度超过1mm的硒锑矿,其化学成分式为Sb1.88(Se2.96,S0.04)3.00,并测得该矿物的反射率色散曲线(其中546nm;R’g=46.2%,R’p=42.3%)。采用魏森堡单晶X射线法首次测得硒锑矿单晶较精确的主要晶体结构参数:α=1.1213,b=1.1515,c=0.3991nm,V=0.51531nm3,Z=4;空间群:Pbnm;斜方晶系。这些资料是对该新矿物已有资料的重要补充。
【Abstract】 Antimonselite is a new selenide mineral discovered in China in 1993. Later, the new mineral,with its single crystals measuring 0. 1~0. 5mm and aggregates >1mm in size, was found by theauthors in the Bentou deposit, a carbonaceous-siliceous-pelitic rock-type uranium deposit, HunanProvince. Its chemical formula is Sb1.88 (Se2. 96, S0.04 )3.00. The reflectance dispersion curve of antimon-selite was obtained (546nm: R’R = 46. 2 %, R’p = 42. 3 % ). The crystal structure of antimonselitehas been studied for the first time using the oscillation and weissenberg single-crystal X-raymethod, giving α = 1. 1213, b= 1. 1515, c= 0. 3991nm; V= 0. 51531nm3; Z= 4; space group Pbnmwith orthorhombic system.
