为了加强区域化探调查工作,77年7月在黄山召开了全国区域化探会议。会议决定要充分挖掘已有区域化探资料的潜力,搞好矿产预测,要求全国各省、市、自治区在80年以前完成现有1:20万区域化探资料的重新整理和研究工作,编制1:20万地球化学图件,为大比例尺地质矿产工作选区及普查勘探工作提供可靠的地球化学依据,并为跨省区小比例尺的地球化学填图及地球化学矿产预测图的编制准备条件。
In order to strengthen the regional geochemical investigation, a national regional geochemical exploration conference was held in Huangshan in July 77. The meeting decided to fully tap the potentials of the existing regional geochemical exploration data and improve the mineral prediction. All the provinces, municipalities and autonomous regions in the country are required to complete the reorganization and research of the existing 1: 200,000 regional geochemical data 80 years ago, and prepare 1 : 200,000 geochemical maps provide a reliable geochemical basis for large-scale geological and mineral work constituencies and census and exploration work and prepare conditions for the preparation of small-scale geochemical mapping and geochemical mineral prospecting maps across provinces.
