问题的提出一九七六年四月,我们参加了冶金部组织的海南富铁会战,先在昌江军营地区完成了170km2 1:2.5万的地质填图与找矿工作,一九七七年上半年又接着在占县和盛地区完成了504km2 1:5万地质填图与普查找矿工作。在工作过程中,934队和我们先后在原认为属华夏褶皱带的寒武-奥陶系“陀烈群”中,找到了不少石炭-二叠纪的可靠化石,其时代肯定属石炭-二叠纪无疑,并命名为军营群。在以上地层中还发现了变质基性-超基性海相火山熔岩(已变质为阳起石岩)。结合从这套地层的沉积建造,构造变形、岩浆活动及区域变质
PROBLEM PROPOSAL In April 1976, we participated in the Hainan Iron-rich Battle organized by the Ministry of Metallurgy. We completed the geological mapping and prospecting of 1: 25,000 km2 at 170km2 in the military camp area of Changjiang River. In 1977, Six months later it completed 1: 50000 geological mapping and prospecting of 504km2 in the counties He Sheng area. In the process of work, 934 team and we have found a lot of Carboniferous - Permian reliable fossils in the Cambrian - Ordovician “Tuoqun” previously thought to be the Huaxia fold belt. Stacks undoubtedly, and named military camp group. Metamorphic basal-ultrabasic marine volcanic lavas (which have been metamorphosed to Yangzidan) have also been found in the above strata. Combined with the deposition from this formation, tectonic deformation, magmatism and regional metamorphism
