| 摘 要： | 通过全国资源潜力评价,结合各省自然重砂资料和全国重砂资料汇总成果,对85个常见自然重砂矿物进行统计分析。研究表明,中国自然重砂矿物复杂多样,重砂矿物分布具有明显的区域性特点。造山带中自然重砂矿物产出数量相对较多且密度较大,而稳定地区重砂矿物相对较少。不同的自然重砂矿物及其组合具有明显的找矿信息,单矿物自然重砂可能来源于相对单一的矿石或岩石,其异常范围表明与其相关的矿产可能具有较好的成矿远景;矿物组合常显示出有关矿床的成因信息。自然重砂矿物与源区岩石或矿石具有密切的成因联系,对指导矿产勘查与研究具有十分重要的意义。

| Abstract: | For the purpose of evaluating national mineral resources, the authors made a systematic statistic analysis of the natural heavy mineral data of over 85 minerals. It is proved that most of the 85 minerals are characterized obviously by regional distribution, with more heavy minerals occurring in geologically active belts rather than in stable areas, indicating that the natural heavy minerals evidently contain abundant information of ore mineral formation and its tectonic significance. Individual heavy minerals often come from the ore deposit or its host rocks, and thus probably provide information on the potential of related metallogenesis. The assemblage of heavy minerals often contains genetic information of the relevant ore deposit. Generally, the natural heavy mineral has closely genetic relationship with the ore deposit or its host rocks, hence having very important significance for mineral exploration and researches. |
