摘要
黄铁矿是张家口金矿中一种十分重要的载金矿物。泰文通过对黄铁矿的形态、粒度、成分、晶胞参数及其热电性等矿物标型的详细研究,发现当细粒,立方体与五角十二面体晶形共同出现,含较高的As,Co和Ni,晶胞参数大以及具有较高热电系数值时的黄铁矿含金性好。综合黄铁矿的这些标型特征所蕴藏的成因信息,可以得出:张家口金矿为中深成中高温变质热液矿床。
Pyrite is a very important gold-bearing mineral in Zhangjiakou gold ore deposit. The authors of this paper study the form, grade, composition, unit cell parameters and pyroelectric property of pyrite of Zhangjiakou gold ore deposit,and find that the pyrite contains higher gold when it is fine grade or with cubic and pyritohedron in paragenesis higher As,Co,Ni, bigger unit cell parameters and higher pyroelectric coefficient. Therefore, according to the genetic meaning based on the typomorphic characteristics of the pyrite,the authors conclude that Zhangjiakou gold ore deposit is a metamorphic hydrothermal one.
