大兴安岭北段新一轮国土资源大调查以来的主要基础地质成果与进展
Main geological achievements and progress of the new round of national land and resources survey in north Daxinganling
摘要
Abstract
The historical evolution of genetic mechanism and tectonic stratum were defind. The strata, intrusive rocks of the mapping units and the regional geological tectonic framework were redefined. The lithologic and structural mapping were strengthend in progress of the project. The results objectively reflected the material composition and structure relation of geological body. The ore-forming conditions and metallogenic regularity were summarized and a new idea of Mesozoic volcanic rock belt and Mohe County basin formed by the Mongolia-Okhotsk ocean and Isawa Nayoshi plate interaction were put forward. Geophysical and geochemical exploration, and remote sensing method were applicated to reveal the geological information covering layer and deepand forest coverage area of geological and prospecting division, which greatly improved the mapping quality. Mesozoic superimposed gold polymetalhc metallogenic geological background and study on mineralization in each stage of ductile shear zone are should be strengthened in the furture关键词
