摘要: 中国萤石矿资源较丰富,探明资源量居世界前列。我国的萤石矿研究工作主要围绕大中型萤石矿床的地质特征、物质来源、成因、区域成矿规律和少数省级萤石矿成矿远景区划、区域萤石矿资源潜力评价展开。为摸清萤石矿资源家底,制定科学合理的经济产业政策,亟需开展系统的、全国性的萤石矿成矿规律和资源潜力评价。依据中国萤石矿资源潜力评价报告数据和成果,文章分析了中国萤石矿矿床类型、矿床地质特征和时空分布特征,划分了成矿区带;在各省区建立的典型矿床预测模型和区域预测模型基础上,以成矿系列理论为指导,突出总结萤石矿成矿要素和预测要素,归纳、汇总、提出了热液充填型和沉积改造型萤石矿矿床预测评价模型;以各省区圈定的最小预测区、归并的2级预测区和估算的资源量为基础,依据预测要素和区域预测模型,归并、圈定了198个3级预测区,汇总估算了全国萤石矿预测资源量,提出了中国萤石矿预测远景区。中国萤石矿资源丰富,找矿潜力大,预测资源量(CaF2)约9.5亿t,其中单一萤石矿预测资源量约4.3亿t,以热液充填型预测资源量为主。预测远景区主要分布于中国东部,四子王旗、冀北—辽西、豫南、皖南—浙西、浙中、闽北—粤东等地区成矿条件好,资源潜力大,是萤石矿预测资源量较大的地区。

Abstract:  China has abundant fluorine mineral resources with its global top ranking in proved fluorite reserves. Previous researches have been mainly focused on the geological setting, material source, genesis and regional metallogeny of medium to large fluorite deposits, with some efforts in prospect zone delineation and resources potential assessment at the provincial level. To investigate the national fluorite resources and to form a scientific and rational economic policy, a nationwide comprehensive fluorite metallogenic survey and resource potential evaluation is urgently needed. Here, based on the survey data assembled under the national mineral resources potential assessment project (20062013), we analyzed deposit types, mineralogical characteristics and spatiotemporal features of fluorite deposits nationwide, and delineated several metallogenic belts. Following the evaluation of metallogenic elements and forecast factors of typical fluorite mines around the country, we proposed two prediction models for fluorite deposits: hydrothermal fluid filling and sedimentary reformation types. According to estimated resources of smallest prediction areas and amalgamated levelⅡ forecast areas of various provinces, we delineated 198 levelⅢ prediction areas and estimated the national fluorite resources. The results showed that China possesses abundant fluorite resources. By our estimation, it has about 9.5 hundred million tons of CaF2, of which 4.3 hundred million tons are in single fluorite ore deposit (mainly hydrothermal filling type) indicating a good prospecting potential. The prospective areas are mainly distributed in eastern China including the Siziwang Banner, northern Hebeiwestern Liaoning, southern Henan, southern Anhuiwestern Zhejiang, central Zhejiang and northern Fujianeastern Guangdong areas, where fluorite resources were predicted to be richer because of excellent oreforming condition with huge resource potential.

Key words: China, fluorite deposits, geological characteristics, predictive evaluation model, resource potential
