华南中、低温成矿带主要由江南古陆的“江南型”金＿锑矿带、湘黔汞矿带、西南卡林型金矿区和湘中锑矿带组成。其成矿时代有自东向西从燕山早期到中、晚期有变新的趋势； 矿种分布和成矿元素组合表现出对元古宇基底的继承性； 成矿流体的温度和盐度在大区域内从东到西和自南向北分别呈现降低和增高的趋势， 并且在古陆西、北侧的盆地中有盆地卤水混合的现象。研究表明， 华南中、低温成矿带的时空分布和成矿元素组合演化与华南燕山期花岗岩强烈活动的华南钨（ 锡） 成矿域有密切的联系。这些大型矿集区都集中形成于燕山期， 并与川东南油气田一起， 共同构成了一个自南东向北西的高—中—低温热液矿床和油气矿藏的区域性矿化巨型分带。从而表现出大华南地区（ 东南、中南和西南） 在燕山期曾经历过统一热场作用下的大范围流体运动和大规模成矿作用
The middle and low temperature metallogenic belts in South China are mainly composed of “Jiangnan-type” gold antimony ore belt, Xiangqian mercury ore belt, Carlin-type gold mining area and Xiangzhong antimony ore belt in Jiangnan ancient land. The ore-forming age tended to change from east to west from the early Yanshanian to the middle and late stages. The mineralization and ore-forming element assemblages showed succession to the metamorphic basement. The temperature and salinity of the ore-forming fluid were large There is a trend of decrease and increase from east to west and from south to north in the region, respectively, and there is a mixture of brine in the basins in the ancient West and North basins. The results show that the spatial-temporal distribution of ore-forming belts and the evolution of metallogenic elements in the intermediate and low temperature metallogenic belt in South China are closely related to the intense tungsten (tin) mineralization in southern China. These large-scale mineral deposits are concentrated in the Yanshanian period and together with the southeast Sichuan oil and gas fields constitute a regional mineralized giant zonation of high-middle-low-temperature hydrothermal deposits and oil-gas deposits from the southeast to the northwest. Thus showing the large-scale fluid movement and large-scale metallogenesis under the unified thermal field in the Great Southern China (southeast, central south and southwest) during the Yanshan period
