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。
In this paper, we established the physicochemical environment of the sedimentary facies of the Middle Devonian Paleocene in the Middle Devonian in the Mabian Mountains in the Central Hunan Province by establishing the geochemical indicators of each sedimentary facies, the indicator elements and the composition of sulfur isotopes. The stratabound lead-zinc deposit in this area is closely related to the sedimentary physical and chemical environment. In this paper, metallogenic simulation experiments further demonstrate the possibility of enrichment of metallogenic elements.
