辽东半岛较大面积出露太古宙变质深成岩和变质表壳岩，富含铁、铜、金等矿产资源。历经3.8 Ga始太古代最古老的奥长花岗岩就位,3.3～3.77 Ga古太古代多期变质深成杂岩就位和3376～3357 Ma表壳岩基性火山岩-陆源碎屑岩建造沉积,其后为中太古代2962～3142 Ma两期花岗杂岩侵位和3.0 Ga表壳岩陆源碎屑岩建造沉积,构成了太古宙早期古陆核,此时构造造演化特点主要以垂直增生为主，并出现原始古洋盆；进入新太古代，原始陆壳裂解为3个古陆块。即：建平—龙岗微古陆块、绥中—鞍山—本溪微古陆块、城子坦微古陆块。3个古陆块于新太古代末—古元古代早期（2500～2400 Ma）碰撞拼合，形成早期太古宙克拉通基底。

Liaodong Peninsula, large area exposed Archean metamorphic plutonic rocks and the metamorphic supracrustal rocks, rich in iron, copper, gold and other mineral resources. After 3.8 Ga Eoarchean Era oldest trondhjemite in place, 3.3~3.77 Ga Paleoarchean Era metamorphic plutonic complex in place and 3 376~3 357 Ma supracrustal rock basic volcanic rock of terrigenous clastic rocks sedimentary formation, followed by 2 962~3142 Ma two stages mesoarchaean granitic complex emplacement and 3.0 Ga supracrustal rock terrigenous clastic rock construct deposition, constitute the early Archaean continental nucleus, this constructed evolution characteristics are mainly vertical hyperplasia, and the emerge original ancient ocean basin; enter into the Neoarchean, original continental crust cracked into three block. Namely: Jianping-Longgang micro continental block, Suizhong-Anshan-Benxi micro continental block, Chengzitan micro continental block. Three continental block collisioed in the end of Neoarchean-early Paleoproterozoic (2 500 ~2 400 Ma), and the early Archean cratonic basement were formed.
