However , it is unsubstantial for the investigation on chorology and geochemisty , and dissimilar for the research on petrogenesis and tectonic setting 但关于它们的年代学和系统的地球化学研究还比较薄弱，且对其成因和形成的构造环境，仍存在着争议。

They all belong to the calc - alkaline island arc series and are closely related to the evolution of the arc - basin systems of the gangdise tectonic belt . based on studies of petrology , litho - geochemistry , tectonic setting , petrogenesis and magmatic evolution , the present dissertation summarized the general evolutionary regularity of the magmatic rocks in time and space . the magmatic rock assemblages are divided into the inter - arc spreading basin t 在对研究区主要矿产分布特征、成因类型系统分析的基础上，总结了措勤地区构造岩浆演化与成矿的关系，并将研究区成矿系统划分为汇聚大陆边缘成矿巨系统、碰撞造山成矿巨系统和陆内汇聚成矿巨系统。

There is a close relation between mesozoic tectonic evolution , fluid evolution , petrogenesis and mineralization in the manzhouli - e ' erguna region in the northeast of the northern orogenic belt , china , and three evolution stages of the mesozoic tectonic - fluid - petrogenetic and metallogenetic system are proposed out : 1 ) acompanied by ree and cu mineralization , the calc - alkaline volcanic rocks and mantle - crust mixed type granite occurred under the regional tension tectonic background caused by the mongolia - okhotsk residual ocean that was closing in scissors form in the early - middle jurassic . 2 ) acompanied by pb , zn and ag mineralization , the calc - alkaline and alkaline volcanic rocks occurred under the regional shear - compression tectonic background in the late jurassic . 3 ) acompanied by u , f , pb , zn and ag mineralization , the caic - alkaline and alkaline volcanic rocks occurred under the regional tension tectonic background in the early cretaceous 摘要本文讨论了北方造山带东北段满洲里额尔古纳地区及其毗邻区中生代构造流体成岩成矿系统及其演化的三个不同阶段： 1 )早中侏罗世张性“似裂谷环境”下所形成的中基性碱性火山岩、同熔性花岗岩及深源流体活动形成的稀土矿床和斑岩性铜铝矿床； 2 )晚侏罗世挤压剪切环境下所形成的酸性火山岩、斑岩类及深源流体活动所形成的铅锌银矿床； 3 )早白垩世张性环境下所形成的基性碱性火山岩及深源流体活动所形成的铀矿床、金银矿床及萤石矿床。
