摘　　要：南岭是世界上最重要的钨矿产地,南岭钨矿床中与钨共(伴)生的有色、稀有及贵金属种类很多,数量可观,也是我国重要的矿产资源。论述了南岭及其邻近地区众多钨矿床中与钨共生或伴生的锡、钼、铋、铌钽、铜、铅锌、金银、稀土等元素的不同状况和特征,其中锡、钼、铋是南岭钨矿床中最普遍最重要的共(伴)生元素,铌钽只在演化程度较高的花岗岩相关的钨矿床中伴生产出,铜、金作为钨矿床伴生金属的意义较小,而钨矿床中伴生的银、铅锌具有相当重要的意义。从元素地球化学性质、南岭的区域地质背景、花岗岩演化、多期多阶段成矿作用等方面出发,分析和解释了它们之间相互共(伴)生的原因及差异性,探讨了其地质意义。The Nanling Range area in South China is the most important tungsten producing district in the world. It also yields great amount of other nonferrous, rare, and precious metal resources as the accompaniments with tungsten mineralization. This paper describes the different situations and characteristics of several accompanying metals, e.g. Sn, Mo, Bi, Ta-Nb, Cu, Au, Ag, Pb-Zn and REE, in tungsten deposits in the Nanling Range and vicinity areas. Sn, Mo, and Bi are the most common and important elements among these accompaniments, whereas TaoNb is only accompanied with W deposits related to highly evolved granitic rocks. Cu and Au are not important accompanying members of tungsten mineralization in this area, while Ag and Pb-Zn are much more common in the Nanling tungsten deposits. The paper also explains the factors which caused the different behaviors of these elements from the view of geochemical features, regional geological backgrounds, evolution of granitic rocks, as well as the superposition of muhi-staged mineralizations. The geological implication of these accompanying relations is also discussed.
