赣南大吉山与漂塘花岗岩及有关成矿作用特征对比

对江西南部大吉山和漂塘两个钨矿床有关的花岗岩的岩石化学和微量元素地球化学特征、成因及其与成矿的关系等方面进行了对比研究，认为两者不同的成矿作用特征主要是由于大吉山花岗岩比漂塘花岗岩的分异演化程度更高而造成的。对前人提出的含钨花岗岩、含钽铌花岗岩及花岗岩产出的动力学背景等问题，也进行了一些初步讨论。

Comparison in the Characteristics, Origin, and Related Metallogeny between Granites in Dajishan and Piaotang, Southern Jiangxi, China

Dajishan and Piaotang are two large tungsten deposits in southern Jiangxi Province, which are all related to granites of continental crust remelting type. Besides W as major product, the Dajishan deposit is also a deposit of Ta and Nb, whereas the Piaotang deposit is rich in Sn, Mo, and Ag. Major and trace element geochemistry of these two granites is studied. Both granites are SiO_2-rich and peraluminous, higher in alkalies, and rich in F and incompatible trace elements. However, the comparison between them shows that the Dajishan granite was formed by more highly evolved magma than the Piaotang granite. This might be the key factor that controlled the different metallogenic characteristics of these two deposits. The commonly used terms such as W-bearing granites, Ta-Nb-bearing granites, and Li-F granites, as well as the geodynamic setting for the granites, is also briefly discussed in this paper.
