青海锡铁山碳质片岩型铅-锌矿床的矿化结构特征

文章应用地质、地球化学分析，对锡铁山矿区新发现的（碳质）片岩型矿体的矿化结构、矿体类型及其典型元素分带特征进行综合研究，得出以下结论：锡铁山矿床具“双层结构”，由大理岩型矿体和碳质片岩型矿体组成；碳质片岩型矿体主要赋存于滩间山群沉积岩组中上部，产出层位高于大理岩型矿体；碳质片岩型矿体的倒转型热水喷流沉积结构与含矿层倒转有关。研究表明，矿区找矿潜力巨大。

Mineralizing structural characteristics of the Xitieshan carbonaceous schist-host Pb-Zn deposit, Qinghai

Applying geological with geochemical analysis to studying mineralizing structure, orebodies types and zoning features of typical elements of （carbonaceous） schist-host orebodies which have been newly discovered in Xitieshan area, it has concluded that the Xitieshan deposit has ＂double layers structure＂, which is composed by marble-host orebodies and carbonaceous schist-host orebodies. The carbonaceous schist-host orebodies mainly occurred in middle-upper part of Tanjianshan Group sedimentary rocks with the occurring horizon higher than that of marble-host ones. The hydrothermal exhalative-sedimentary structure of carbonaceous schist-host ores is related to ore-bearing strata＇s inversion. The study has shown a great potential for prospecting in this ore area.
