贵州省印江县洋溪铅锌矿构造序次划分与成矿关系探讨

通过对印江洋溪铅锌矿岩矿鉴定测试,从微观上矿区可划分为4个构造序次,各构造序次"原岩"的破坏程度、形成的结构构造、产生的矿化特征、蚀变特征均显现出不同的面貌,形成了石英→黄铁矿、闪锌矿→方铅矿、白云石→方解石的矿物生成顺序。铅锌矿为二、三构造序次析出,具有找矿指导意义。     

Sol–gel modified method for obtention of gray and pink ceramic pigments in zircon matrix

A sol–gel modified method for obtention of gray and pink ceramic pigments in zircon matrix is discussed in this work. The chromophoric powders were firstly well dispersed in the solution containing zirconium and metasilicate ions before gelation and the product ceramic pigments obtained by calcining the xerogel with mineralizers. The zircon was well crystallized at 1,050 °C with the yield about 97%. The mineralization mechanism of the zircon formation was also discussed.
