为了总结过去一年多来富铁矿地质工作的成果,交流找矿经验,制定南方富铁矿地质工作计划,争取在短期内富铁矿地质工作有较大的突破,冶金地质南方富铁矿协作小组第三次会议,在冶金部和云南省科委、云南省冶金局的亲切关怀下,于今年四月三日至十二日在昆明市召开。参加会议的有关单位的代表共180多名。一年多以来,南方各省(区)在富铁矿地质工作中,探明了一定的富铁矿储量,找到了一批有远景的普查勘探基地,提供了不少可供建设的矿区的地质报告。在成矿理论和找矿方向上,对海南石碌式富铁矿的成因和时代提出了一些新看法;对矿床的“层控”现象普遍受到重视;对菱铁矿床的工业意义和找矿前景有了新认识;对海相火山
In order to summarize the achievements made in the past one year and more in the geological work of iron ore deposits and to exchange experience in ore prospecting and work out the geological work plan for the iron ore deposits in the south and to strive for a major breakthrough in the geology work of the iron ore deposits in the short term, The third meeting of the collaborative group was held in Kunming on April 3 to April 12 with the kind attention of the Ministry of Metallurgy and the Yunnan Provincial Science and Technology Commission and the Yunnan Provincial Metallurgical Bureau. More than 180 representatives of the participating units attended the meeting. In the past year or so, all the provinces (regions) in the south have proved a certain amount of rich iron ore reserves in the geological work of iron ore deposits and have found a number of long-term census exploration bases that provide a lot of geology for mining areas that can be built report. In terms of metallogenic theory and prospecting direction, some new opinions are put forward on the genesis and era of Hainan-Shilu iron-rich ore deposit. The “stratabound control” phenomenon of the deposit has been generally valued; the industrial significance and prospect of the siderite deposit There is a new understanding of the prospect of the mines; volcanoes on the sea
