南岭成矿规律与百年勘查成果及新一轮找矿建议——《中国矿产地质志·南岭卷》研编

The metallogenic regularities,century exploration achievement,and suggestions of new round of prospecting in Nanling Metallogenic Belt——Compilation of Mineral Geology of China·Nanling Volume

南岭成矿带是华南乃至全国最为重要且独具特色的成矿带之一,对其成矿规律的探索研究虽然历史悠久但每一次的成果总结都会推进新一轮找矿突破。笔者等在前人大量研究资料的基础上,对南岭成矿带的能源矿产(煤矿和铀矿)、有色金属矿产(钨、锡、钼、铋、铜、铅锌等)、贵金属矿产(金矿和银矿)、稀有金属和稀土金属矿产、非金属矿产(萤石)的成矿特征、时空分布规律进行了总结,并将南岭成矿带矿产按前寒武、加里东旋回、华力西旋回、印支旋回、燕山旋回及喜马拉雅旋回6个旋回厘定出21个矿床成矿系列和23个矿床成矿亚系列,为区域矿产勘查工作部署及成矿预测奠定了理论基础。为了保障能源资源安全,笔者等提出了南岭成矿带区块出让的原则性意见和柿竹园、香花岭、崇余犹、富贺钟、坪宝、三南等15个大型资源基地找矿的建议,为新一轮找矿突破战略行动提供了科学指导。

Nanling metallogenic belt is one of the most important and distinctive polymetallic,nonmetallic and energy mine metallogenic belts in South China and even in China.There is a long-term history of the study in metallogenic law,however each summary of achievements is greatly benefit for the new round of prospecting.Based on the abundant previous research data,the regional geology of the Nanling metallogenic belt are summarized in this study.The spatial and temporal distribution and metallogenic characteristics of critical energy minerals(coal and uranium),non-ferrous minerals(tungsten,tin,molybdenum,bismuth,copper,lead—zinc,etc.),precious metals(gold and silver),rare metals and rare earth minerals,non-metallic minerals(fluorite)are discussed in detail.Moreover,the mineral deposits in Nanling metallogenic belt can be divided into 21 metallogenic series and 29 sub-series according to the 6 tectonic epoches of Precambrian,Caledonian,Variscan,Indonisian,Yanshanian and Himalayan.Thus,it provides a basis for further regional mineral exploration deployment and metallogenic prediction.In order to ensure the security of energy and resources,this study proposed the principle opinions on the block transfer of Nanling metallogenic belt and suggestions on prospecting in 15 large-scale resource bases such as Shizhuyuan,Xianghualing,Chongyu,Fuhezhong,Pingbao and Sannan,which provide scientific guidance for new round of prospecting.
