| 摘 要： | 本文通过建立各沉积相的地球化学指标和研究指示元素及硫同位素组成,对湘中大乘山区中泥盆世棋梓桥期沉积相的物理化学环境作了探讨。该区层控铅锌矿床和沉积物理化学环境有密切的关系。文中还以成矿模拟实验进一步论证了成矿元素同生富集的可能性。

| Abstract: | Based on the studies of indicator elements, sulfur isotope, and geochemical index marks of the sedimentary fades, the physicochemical environments of sedimentary facies of Qiziqiao age in Middle Devonian in Dashengshan area are approached,One of these environments is found to be
closely related to the metallization of the stratabound Pb-Zn deposits in this area. Furthermore, the potential of syngenetic enrichment of the ore-forming elements has been substantiated by the simulated experiments. |
