| 摘 要： | 块体拼贴是东北大地构造格架的基本特征,文中拟从这一构造背景出发,在区域地质研究基础上,选择目前研究相对薄弱的松嫩地块进行讨论.通过地层建造、古生物地理分区、构造-岩浆组合及年代学的资料,揭示松嫩地块与东北其他地质体拼贴的历史.松嫩地块西侧通过嫩江中古生代造山带与兴安褶皱带相接;南侧通过吉中晚古生代造山带和华北地台北缘的...

| Abstract: | Matching of massifs is one of the basic characteristics of Northeast China geotectonic framework.Upon such a background,the Songnen Massif,which has been relatively poorly researched,is studied in the present work in terms of its regional geology.The history of Songnen Massif matching with adjacent massifs has been explored through stratigraphy,palaeobiogeographic zoning,tectono-magmatic assemblage and isotopic chronology.It is found that the Songnen Massif is connected with Higgan foldbelt through the Midd... |
