| 中文摘要:硼矿是重要的化工矿产资源，广泛应用于玻璃工业、陶瓷工业、洗涤剂和农用化肥。2014年至今，中国地质调查局组织编写的中国矿产地质志，全面总结了中国硼矿的资源特征和成矿规律。文章依托中国矿产地质志项目，总结了中国硼矿的成矿规律，圈定了硼矿找矿远景区，对未来硼矿的找矿工作有一定的参考价值。文章选取了具有代表性的矿床进行详细解剖工作，分别建立了现代盐湖型和沉积变质型典型硼矿床的预测模型。中国硼矿床的主要类型包括现代盐湖型、沉积变质型、地下卤水型、矽卡岩型和海相火山岩型。目前，中国共发现硼矿的矿产地216处，查明资源储量7575.69万t（B2O3），分布在辽宁、西藏、青海、湖北等14个省（市、自治区）。在成矿时代上，中国硼矿主要形成于新生代、古元古代和中生代。在空间上，中国硼矿可划分为14个Ⅲ级成矿区带和11个矿集区。根据硼矿成矿预测成果，本文圈定了10个硼矿找矿远景区和8个优先勘查区，其中优先勘查区主要集中在青海油泉子（地下卤水型），昆特依（现代盐湖型），辽宁夹皮沟-红石砬子、吉林高台沟（沉积变质型），西藏扎布耶茶卡、依布茶卡、麻米错、班戈错（现代盐湖型）等地区。 |

| Abstract:Boron ore is an important chemical mineral resource, which is widely used in glass industry, ceramic industry, detergent and agricultural fertilizer. Since 2014, the compilation of Annals of Geology of Mineral Resources of China has been organized by China Geological Survey, which comprehensively summarizes the resource cha-racteristics and metallogenic regularity of boron deposits in China. Based on the project of Annals of Geology of Mineral Resources of China, this paper systematically summarizes the metallogenic regularity of boron deposits in China and delineates the potential prospecting areas of boron ore, which has certain reference value for explo-ring boron deposits in China in the future. In this paper, the representative boron deposits are selected for detailed study and the prediction models of modern salt lake type and sedimentary metamorphic type boron deposits are established respectively. The main types of boron deposits in China include modern salt lake type, sedimentary metamorphic type, underground brine type, skarn type and Marine volcanic rock type. Up to now, there are 216 boron mines/deposits in China with 75 756 900 tons of confirmed resources/reserves (B2O3), which is distributed in 14 provinces (or municipalities, autonomous regions) including Liaoning, Xizang, Qinghai and Hubei. In terms of metallogenic age, boron deposits in China are mainly formed in Cenozoic, Paleoproterozoic and Mesozoic. In space, boron deposits in China are mainly concentrated in 14 grade Ⅲ metallogenic belts and 11 ore concentration areas. According to the results of boron ore-forming prediction, 10 boron ore-prospecting potential areas and 8 high priority exploration areas are delineated. In the future, the exploration focus of boron deposits in China should be the Youquanzi area (underground brine type) and Kunteyi area (modern salt lake type) in Qinghai Pro-vince, the Jiapigou-Hongshilazi area in Liaoning Province and Gaotaigou area in Jilin Province (sedimentary me-tamorphic type), the Zabuyechaka, Yibuchaka, Mamico, Bango Co areas etc. in Xizang (modern salt lake type). |
