桐柏矿是电子探针分析过程中首先发现,经X光分析后确定的(见图1,2).矿物化学式为Cr_3C_2,属斜方晶系.桐柏矿作为新矿物已于1982年3月份被国际新矿物及矿物命名委员会以全票(17票赞成,0票反对)通过,该矿物的名称也于1983年2月11日由该委员会以13:0票通过. 桐柏矿定性分析表明,含铬及小量铁和镍.矿物组成元素赋存状态研究表明矿物除边部有
Tongbai mine was first discovered during the electron probe analysis and was confirmed by X-ray analysis (see Figures 1 and 2). The mineral chemical formula is Cr_3C_2, belonging to the orthorhombic system. Tongbai Mine, as a new mineral, was discovered in 1982 The month was approved by a full vote (17 votes in favor and 0 against) by the International Commission of Mines and Mineral Nomenclature, which was also adopted by the Commission on 13 February 1983 with the vote of 13: 0. The qualitative analysis of Tongbai Mine , Chromium and a small amount of iron and nickel.Studies on the occurrence of mineral elements show that the addition of the edge of the mineral
