对满洲里-额尔古纳地区中生代塔木兰沟组、上库力组火山岩地球化学特征研究表明，它们形成于蒙古-鄂蒙茨克残余洋“剪刀式”闭合的总体构造背景下，但各组火山岩形成的具体构造属性不尽相同。塔木兰沟组火山岩形成于蒙古-鄂霍茨克残余洋开始“剪刀式”闭合，布列亚-佳木斯地体逆时针旋转的拉张环境；上库力组火山岩形成于布列亚-佳木斯地体剪切-走滑拼合的挤压环境；梅勒图组火山岩形成于张性裂陷环境。反映了中侏罗世-早白垩世本区处于旋转、拉张-挤压、走滑拼合-再旋转拉张的地球动力学过程。
The geochemical characteristics of the Upper Cretaceous volcanic rocks in the Mesozoic Tamenglanggou Formation in the Manchuria-Ergun area show that they were formed under the “scissors-like” closed tectonic setting of the Mongolian-Ehrendequi residual ocean. However, Volcanic rock formation of specific structural properties vary. The Tamulanggou volcanic rocks formed in the Mongolia-Okhotsk remnant ocean and began the “scissors-type” closure and the Bria-Jiamusi land rotated counterclockwise. The volcanic rocks of the Upper Kuliu Formation formed in Briajamuji Body shear - Squeeze extrusion environment; Meltu group volcanic rocks formed in the tensile environment. It reflects the geodynamics process of the region from middle Jurassic to early Cretaceous in rotation, tension-compression, strike-slip combination-re-rotation.
