摘要
在对所收集到的861处中国稀散金属矿产地(大部分矿产地涉及多个矿种)地质信息资料进行分析的基础上,将中国稀散金属矿床类型划分为浅成中-低温热液型、化学沉积型、生物化学沉积型、矽卡岩型、岩浆热液型、风化型、斑岩型、岩浆型、海相火山岩型、陆相火山岩型、斑岩-矽卡岩复合型等11种主要类型。中国稀散金属矿成矿时代主要集中在晚古生代和中生代,燕山期和华力西期为最重要的成矿时代;空间上可划分出42个稀散金属成矿带,其中,上扬子中东部、华北陆块南缘、长江中下游、山西(断隆)、南岭、桂西-黔西南-滇东北、浙闽粤沿海等成矿带是中国稀散金属矿的重要成矿带,也是具有找矿潜力的重要区带;铅锌矿、铝土矿、煤矿、铜钼、铜镍、铜、铁多金属矿是寻找伴生稀散金属矿的重要矿种;加强矿山开采过程中伴生矿产的综合评价,提高现有在采矿山的稀散金属的综合回收率,也是增加稀散金属矿产资源量的重要途径。
Based on the geological information collected from 861 dispersed metals occurrences in China(most of which include several deposits),the dispersed metal deposits in China are divided into 11 main deposit types,including meso-epithermal type,chemical deposition type,biochemical deposition type,skarn type,magmatic-hydrothermal type,weathered type,porphyry type,magmatic type,submarine volcanic rock-hosted type,subaerial volcanic rock-hosted type,and porphyry-skarn composite type.The mineralization periods of dispersed metal deposits in China are mainly concentrated in the Late Paleozoic and Mesozoic,with the Yanshannian and Variscan being the most important mineralization periods;In space,42 dispersed metal metallogenic belts can be divided.Among them,the mid-eastern region of the Upper Yangtze Block metallogenic belt,the southern margin of the North China Craton metallogenic belt,the Middle-Lower Yangtze River metallogenic belt,Shanxi(fault uplift)metallogenic belt,Nanling metallogenic belt,west Guangxi-southwest Guizhou-northeast Yunnan metallogenic belt,and the coastal areas of Zhejiang-Fujian-Guangdong are important metallogenic belts of dispersed metal deposits in China,as well as important regions with prospecting potential;Lead-zinc deposit,bauxite deposit,coal deposit,copper-molybdenum deposit,copper-nickel deposit,copper polymetallic deposit and iron polymetallic deposit are important deposits for searching for dispersed metals.Strengthening the comprehensive evaluation of associated resources in the mining process and improving the comprehensive recovery of dispersed metals in mining mines are also important ways to increase dispersed metals resources.
