辽东地区古元古代条痕状花岗质杂岩呈东西向展布于辽东古裂谷带中，侵入辽河群，最高可达大石桥岩组。曾被认为是幔源岩浆结晶分异，或壳源重熔岩浆侵位的产物。岩石化学和地球化学研究表明，杂岩属钙碱性，是以S型花岗质岩为主的I型与S型的混合型花岗岩。杂岩物源主要来源于壳源区火山－沉积岩和壳幔过渡区的玄武岩－沉积岩，是壳幔混合层部分熔融体在伸展机制向挤压机制启动期转化阶段形成的复杂岩石，可称壳幔混合杂岩。
Paleoproterozoic striated granitic complexes in the Liaodong area are distributed east-west in the Liaodong ancient rift zone and invade the Liaohe Group, reaching up to the Dashiqiao Group. It has been considered as the product of mantle-derived magma crystallization differentiation or emplacement of crustal remelted magma. Petrochemical and geochemical studies show that the complex is calc-alkaline and is a type I and type S mixed granite dominated by S-type granitic rocks. The source rocks of the complex are mainly derived from the basalt-sedimentary rocks in the crust-source volcanic-sedimentary rocks and the crust-mantle transitional zone, which is a complex rock formed by the partial melting of the crust-mantle mixed layer during the transitional phase from extension mechanism to extrusion mechanism. Mantle mixed complex.
