通过地质与地球化学资料的综合分析 ,揭示出胶辽地块古元古代前造山期深部地质过程主要为岩浆底板垫托作用 ,且具有 3个特性 ,即幕式活动性、样式不对称性及空间上向南的迁移规律。受这一深部过程影响 ,在壳内引起了 2 .4Ga的基性岩墙侵位事件 ,古元古代裂谷带中双峰式火山活动 (2 .4～ 1 .9Ga) ,巨量早期二长花岗岩的形成与侵位 (主要为 2 .2～ 1 .9Ga) ,二长花岗岩的侵位又引发盖层内改造型滑脱变形 (2 .2～ 1 .9Ga) ,伴生顺层伟晶岩脉事件及低压高温变质和垂向顺层递增变质带等特殊拉张变质现象。
Through the comprehensive analysis of geological and geochemical data, it is revealed that the deep Paleoproterozoic orogenic stages of the deep Paleoproterozoic in the Jiaoliao block mainly dominate the magma floor, and have three characteristics, namely, the activity of the curtain, the asymmetry of the pattern and Spatial migration to the south. Affected by this deep process, the emplacement of 2.4-gigagenic basement wall occurred in the crust, the bimodal volcanic activity (2.4-1.9Ga) in the Paleoproterozoic rift zone, Long granite formation and emplacement (mainly 2.2 ~ 1.9Ga), the emplacement of the monzonitic granite led to the remodeling within the caprostoid slippage (2.2 ~ 1.9Ga), associated bedding Pegmatite Pulse events and low-pressure high-temperature metamorphism and vertical bedding along the metamorphic belt and other special tensile deformation phenomenon.
