【摘要】 随着经济的发展,萤石矿作为我国重要的战略资源,其开发利用前景十分广阔,但是,经过几十年的大规模开采,易于发现的露头矿、浅部矿和已知矿日趋减少,找矿难度不断加大。所以,对我国萤石矿资源开发利用选区进行评价,并加强地质勘查研究,进行隐伏-半隐伏矿定位预测具有重要的理论意义和实际应用价值。本论文通过比较分析国内外萤石矿资源开发利用现状及供需形势,结合与萤石的相关行业发展态势,应用统计分析方法对今后5-10年我国的萤石需求量及开发利用前景进行了定量预测;综合分析了影响我国萤石资源开发利用战略选区的主要因素,初步建立了战略选区评价指标体系,并应用此评价体系对我国萤石资源比较丰富的省区进行了定量评价排序;然后,选择排序第二的内蒙古自治区,对其萤石重要产地-赤峰市,进行了萤石矿潜力评价和找矿预测,认为研究区域萤石矿成矿地质条件有利,找矿潜力大。并根据萤石矿成矿有利条件和已知矿化线索发育特征,将研究区域萤石矿的战略性找矿靶区分为两类,包括:林西、翁牛特旗、敖汉旗、喀喇沁旗等A类重点区以及林东的西北部、大板东部-天山一带、克什克腾旗经棚周边地区等B类远景区等;最后,以赤峰地区敖汉旗小四家-小龙凤沟萤石矿带为例,以矿床地质研究为基础,以物探甚低频电磁测量(VLF-EM)和EH4电导率成像等方法为依托,开展了覆盖区隐伏萤石矿床(体)定位预测评价技术方法的创新探索,初步查证了小四家-小龙凤沟萤石矿带的资源远景规模。更多还原

【Abstract】 1 With the development of economy, fluorite, as an important strategic resource in China, has got quite bright development prospects. However, after decades of large-scale exploration, the easily-found outcrop mine, shallow mine and known mine are reducing and the difficulty for ore-finding is enlarging. Therefore, it is significant both theoretically and practically to have assessment of fluorite block and strengthen geological exploration and research to predict the locations of concealed and semi-concealed fluorite deposits.This paper, with relevant industrial development tendency as the basis, has compared and analyzed current domestic and foreign developments, and supply and demand situation of fluorite resources, and through meta-analysis, made quantitative forecasts on the demand and development prospects in the following 5-10 years in China. After analyzing the main factors that influence the strategic area selection of fluorite resources in China comprehensively, this paper has formed an evaluation indicator system for strategic selection, on which a quantitative ordination of the provinces and areas has been made that have abundant fluorite resources. Then, the author makes potential assessment and prediction of fluorite in Chifeng, an important fluorite place in Inner Mongolia----------the top second in the quantitative ordination, and learns that the studied area has advantages for fluorite metallogenic and potentials for ore-finding. According to the advantages for fluorite metallogenic and the development characters of known mineralized cues, the author divides the prospecting target of fluorite in the studied area into two categories---------- Class A, the key target, including Linxi, Wengniuteqi, Aohanqi and Kelaqinqi; Class B, the prospecting target, including northwest of Lindong, Daban-----Tianshan and the surrounding areas of Jingpeng, Keshenkeqi. In the end, with the study of mineral deposit geology as basis, and VLF-EM and EH4 electromagnetic image as main methods, this article, taking Xiaosijia-Xiaolongfenggou fluorite mineral belt in Aohanqi, Chifeng area, as an example, shows the innovative exploration in evaluative methods for the location prediction of the concealed fluorite deposits in the covering area, and confirms the prospects and resource scale in Xiaosijia-Xiaolongfenggou fluorite mineral belt.更多还原
