由省地质学会前寒武纪专业委员会,东川市地质学会和东川矿务局联合召开的“东川矿区深入找矿学术讨论会”于1984年12月20—25日在东川市汤丹召开。到会代表共98名,有12位专家,学者在会上作了学术报告,尤其是过去曾在东川工作的第一冶金地质勘探公司的王可南副总工程师,四川省地矿局胡正纲副总工程师、吴景天高级工程师以及省地质学会理事长李希勣高级工程师等的报告,受到与会代表的热烈欢迎。与会代表一致认为:此次会议是继1973年“东川铁铜矿床座谈会”后的又一次盛会。1973年会议的成攻标志是解脱了“岩浆热液成矿”的束缚,初步总结了“沉积——成岩成矿”在指导找矿、科研方面取得的新经验、新成果。十一年后举行的这次会议,除了肯定上次会议所取得的成绩之外,着重指出:“沉积——成岩”成矿说,尚不能全面合理解释东川式层控铜矿的某些地质
By the Precambrian Special Committee of the Provincial Geological Society, Dongchuan Geological Society and the Dongchuan Mining Bureau jointly held the “Dongchuan Mining District in-depth prospecting Symposium” in December 1984 December 20-25 in Dongchuan City soup Dan convened. A total of 98 delegates to the conference, 12 experts and scholars made academic presentations at the conference. In particular, Wang Kean, deputy chief engineer of the First Metallurgical Geological Exploration Company who had worked in Dongchuan in the past, and Vice President Hu Zhenggang of the Sichuan Bureau of Geology and Mineral Resources Engineer, senior engineer Wu Jingtian and Li Gejiu, director of Provincial Institute of Geology and other senior engineer report, received a warm welcome by the delegates. The delegates agreed that this conference is another grand gathering following the “East Sichuan Iron and Copper Deposit Symposium” in 1973. The sign of attack in 1973 conference was to free the shackles of “magmatic hydrothermal mineralization” and to summarize the new experiences and new achievements of “sedimentary-diagenetic mineralization” in directing prospecting and scientific research. In addition to affirming the achievements made at the previous meeting, the conference held eleven years later highlighted that “sedimentary-diagenetic” mineralization indicates that it is not yet possible to give a complete and reasonable explanation for some of the Dongchuan-type controlled copper deposits Geology
