南岭东段大金山钨锡多金属矿大坳矿段是典型的石英脉型矿床，含矿石英脉具有近地表以钨锡矿化为主，而深部以钼矿化为主的垂向分带规律，且在岩体与地层接触界面附近发育一组与接触面近平行的含钼石英脉。大坳矿段钨锡钼的矿化呈现出上钨锡下钼的分带规律。理论上黑钨矿、锡石通常为相对高温的矿物，一般应发育于相对靠近岩体的高温环境，而辉钼矿为相对低温的矿物，似乎应发育于相对远离岩体的低温环境，初步分析后认为，该矿段的逆向分带特征主要由钨、锡与钼之间不同的地球化学亲和性造成的。

Da’ao ore block of Dajinshan W-Sn polymetallic deposit, which locates in the east of Nanling Yunfu district Guangdong province, is considered as the typical type of mineralized quartz veins related to the Yanshan-nian granite. The mineralization is provided with the vertical zonation of epizonal W-Sn and plutonic Mo mineral-ization. Moreover one group of quartz veins bearing Mo take shape parallel to the contact between the intrusion and the stratum. The mineralization of Da’ao W-Sn-Mo deposit present on Mo under the W-Sn. In the abstract, both wolframite and cassiterite are usually regarded as relatively high-temperature minerals, should generally be developed in a relatively high temperature environment near the intrusive rock. Conversely, molybdenite is rela-tively low-temperature mineral, it seems to be developed in a relatively low-temperature environment far from the intrusive rock. This reverse vertical zonation of epizonal W-Sn and plutonic Mo in Da’ao ore block was prelimi-nary attributed to the different geochemical affinities among tungsten, tin and molybdenum.
