The demand for fluorite resource is increasing rapidly as most fluorite deposits on Earth’s surface have been exhausted. The newly discovered fluorite deposits in Inner Mongolia are hosted by Permian metamorphosed sandy slate, intermediate-acid intrusive rocks and Cretaceous volcanic sedimentary rocks. The ore bodies are strictly controlled by faults and buried by cover rocks. The feasibility and effectiveness of multi-techniques for prospecting concealed fluorite ore bodies are evaluated, and 10 anomalies are delineated. On the basis of geological features and effectiveness of different methods, the optimum combinations of ore prospecting techniques are proposed for the exploration of zonal type and burial type concealed fluorite ore bodies. Based on comprehensive researches, an integrated exploration model is proposed: (i) select key prospecting targets based on geological backgrounds, regional geochemical anomalies of F and Ca, and remote sensing images; (ii) identify the spatial distribution of low resistivity anomaly and ore-controlling structure from geophysical survey; (iii) evaluate the mineralization potential in fault zone based on F and Ca anomalies in key sections selected from low resistivity anomaly zones; and (iv) evaluate the mineralization potential and reveal the spatial distribution of fluorite ore bodies and ore-controlling faults based on integrated geophysical and geochemical anomalies. The integrated exploration model is verified to be a powerful tool for prospecting concealed fluorite ore bodies in coverage area.

隐蔽矿床的综合勘探模型:以内蒙古水头萤石矿床为例

萤石资源的需求正在迅速增加,因为地球表面上的大多数萤石沉积物已被消耗exhaust尽。内蒙古新发现的萤石矿床是由二叠纪变质的砂岩,中酸性侵入岩和白垩纪火山岩沉积岩组成的。矿体受到断层的严格控制,并被覆盖岩掩埋。评估了多种技术对隐蔽萤石矿体找矿的可行性和有效性,并划定了10个异常。根据地质特征和不同方法的有效性,提出了探矿技术的最佳组合,用于分区带和埋藏式萤石矿体的勘探。在综合研究的基础上,提出了一种综合勘探模型:(i)根据地质背景,F和Ca的区域地球化学异常以及遥感图像选择主要的勘探目标;(ii)通过地球物理调查确定低电阻率异常和控矿构造的空间分布;(iii)根据选自低电阻率异常区的关键部分的F和Ca异常,评估断层带的矿化潜力;(iv)根据综合的地球物理和地球化学异常,评估矿化潜力并揭示萤石矿体和控矿断层的空间分布。经验证,该综合勘探模型是在覆盖区域内勘探隐蔽萤石矿体的有力工具。(ii)通过地球物理调查确定低电阻率异常和控矿构造的空间分布;(iii)根据选自低电阻率异常区的关键部分的F和Ca异常,评估断层带的矿化潜力;(iv)根据综合的地球物理和地球化学异常,评估矿化潜力并揭示萤石矿体和控矿断层的空间分布。经验证,该综合勘探模型是在覆盖区域内勘探隐蔽萤石矿体的有力工具。(ii)通过地球物理调查确定低电阻率异常和控矿构造的空间分布;(iii)根据选自低电阻率异常区的关键部分的F和Ca异常,评估断层带的矿化潜力;(iv)根据综合的地球物理和地球化学异常,评估矿化潜力并揭示萤石矿体和控矿断层的空间分布。经验证,该综合勘探模型是在覆盖区域内勘探隐蔽萤石矿体的有力工具。(iv)根据综合的地球物理和地球化学异常,评估矿化潜力并揭示萤石矿体和控矿断层的空间分布。经验证,该综合勘探模型是在覆盖区域内勘探隐蔽萤石矿体的有力工具。(iv)根据综合的地球物理和地球化学异常,评估矿化潜力并揭示萤石矿体和控矿断层的空间分布。经验证,该综合勘探模型是在覆盖区域内勘探隐蔽萤石矿体的有力工具。
