摘　　要："中南地区矿产资源潜力评价"项目按照《全国矿产资源潜力评价技术要求》的统一规定,对中南地区铁等20个重要矿种,从成矿地质背景、地球物理、地球化学、遥感、自然重砂、成矿规律、资源预测、成矿作用和找矿方向等方面进行了全面、系统的资料汇总和综合研究;在分析重要矿产的成矿地质背景和划分构造单元的基础上,提出了对扬子陆块与武夷—云开造山带西南段界线等的新认识及其证据;通过总结区内不同大地构造相、不同时代重要矿产的成矿作用和时空分布规律,圈定了物探、化探、遥感和自然重砂的各类综合异常,编制了系列图件,研建了各类数据库系统;客观评价和定量预测了重要矿产的资源潜力,圈定了找矿远景区,指出了找矿方向。该项目取得的各项成果为今后开展更加深入的区域成矿规律研究和矿产勘查提供了翔实可靠的地质依据。The main achievements and knowledge of mineral resource potential evaluation in Central- southern China are got by the project named ‘Technical requirements of national mineral resource potential evaluation’. In this paper,the authors analyzed metallogenic geological background,geophysics,geochemistry,remote sensing,natural heavy fraction,metallogenic regularity,mineral resource prediction,metallogenesis and prospecting direction for 20 important minerals in Central- southern China. On the basis of metallogenic geological background analyses of the important mineral deposits and tectonic unit division,some new evidences and cognitions about boundary of Yangtze landmass and Wuyi- Yunkai orogenic belt are proposed. The comprehensive anomaly of the various kinds of geophysical,geochemical,remote sensing and natural heavy fraction,a serial of maps,and various kinds of data bases were determined through summarizing different tectofacies,metallogenesis in different eras,and spatial- temporal distribution characters of the important mineral deposits in this area. The important mineral resources potentials are quantitatively evaluated and mineral prospective areas are delineated. Besides the prospecting directions are indicated. These achievements will provide reliable foundation for the regional metallogenic regularities and promote the mineral exploration in Central- southern China.
