封面故事:湘东北大万金矿集区深部验证钻探及蚀变岩型矿化。江南造山带湖南段被誉为“金腰带”, 呈带状分布, 累计探明金资源储量达600 t, 集聚了湖南90%以上的金矿, 且多数矿床勘查深度不足 500 m。近期实施的深部验证钻探, 以ZK808钻孔为例, 在1900 m处(孔深2105.35 m)见矿平均品位4.35 g/t, 真厚度3.75 m, 指示“金腰带”深部找矿潜力巨大, 详见本期230-252页。本期专辑着重介绍了中国地质科学院矿产资源研究所肖克炎研究员在内的多个研究团队在深部综合信息矿产资源预测评价研究中的最新认识和进展。(图片提供:黄建中)
Cover Story:Verification drilling and altered rock type mineralization in the depth of the Dawan ore concentration area, northeastern Hunan. The zonal distributed Hunan section of the Jiangnan orogenic belt noted as the “gold belt”, accounts for over 90% of the gold deposits in Hunan Province with total proven gold reserves up to 600 t, and most explora-tion drills for mineral deposits are less than 500 m in depth. Recently, deep validation drills indicated great mineral potential in this “gold belt”. For example, ZK808 (drilling depth 2105.35 m) in Dawan gold mine, northeast Hunan Province, spotted an average ore grade of 4.35 g/t at depth 1900 m, with true thickness of 3.75 m. For details see pp. 230-252 of this issue. This issue reports the advances and new insights of prediction and assessment of deep mineral resources based on integrated geoinformation, pio-neered by Professor XIAO Ke-yan, Institute of Min-eral Resources, Chinese Academy of Geological Sciences and research groups therein.
