今年3月20日至4月8日,在西昌——滇中前震旦系研究协作领导小组的组织安排下,云南省地矿局、西南冶金地勘公司、四川省地矿局、四川省冶金地勘公司及所属的有关单位,与成都地矿所、天津地矿所、中科院南京地质古生物所等21个单位共44名代表“会诊”了云南的易门、东川,四川的会理黎溪、通安香炉山等地;4月9日至11日集中在会理进行了系统深入的讨论。通过野外“会诊”和在会理的讨论,提出了昆阳群、会理群划分对比的多种方案,经归纳可大致分为五种(见表1至表5),它将促进今后对“两群”继续深入进行划分对比的研究,每种方案均有待今后地质工作和有关工作中的实践检验。 (根据西昌——滇中前震旦系现场“会诊”纪要,本刊有删节)
From March 20 to April 8 this year, under the organization and arrangement of the Xichang-Yunnan Central Pre-Sinian Research Collaboration Leading Group, Yunnan Bureau of Geology and Mineral Resources, Southwest Metallurgical Exploration Company, Sichuan Bureau of Geology and Mineral Resources, Sichuan Metallurgy Geological Exploration Company and its related units, together with the Chengdu Institute of Geology and Mineral Resources, Tianjin Institute of Geology and Mineral Resources, Institute of Geology and Palaeontology, Chinese Academy of Sciences, a total of 44 representatives of 21 units “consultation” in Yunnan Yi Men, Dongchuan, Sichuan Huili Creek, Tonglu incense burner Hill and other places; April 9 to 11 concentrated in Huili conduct a systematic discussion. Through the field “consultation” and the discussion in Huili, a variety of schemes of dividing and comparing Kunyang group and Huili group were put forward, which can be roughly divided into five categories (see Table 1 to Table 5) The “two groups” continue to carry out in-depth studies on the division and comparison of each kind of programs, which are to be examined in practice in geological work and related work in the future.
