摘要
胶东、辽东、朝鲜北部三区在地质上表现出了极大的相似性和稳定性。它们不但在元古代地层上可以相互对比,而且还有着一个统一的硼的地球化学省,在大地构造单元上也可以相互衔接。三区可以拼合为一个整体,使辽东的丹东金矿区、朝北的平安北道金矿区和胶东的招掖金矿区正好合成一个完整的整体,构成了一个巨大的金矿集中区。这个巨型金矿集中区是在统一的古陆块上由同一成因作用形成的,后因大陆的张裂和离散被分离。文中对它的分离机制和过程进行了探讨。
The region covering east areas of Liaoning and Shandong provinces and north Korea iscalled 'Jiao-Liao-Chao' for short. The three provinces are very similar in respect to ore bearing hori-zons, minerogenic elements and deposites features. Moreover, they have unified boron geochemicalprovince. The above mentioned three districts may jigsawed well in tectonics and geomorphology tomake up a huge concentration region of gold depoits. The vast concentration region of gold depositsvery likely formed in the same landmass and were sepeated by tensile tears later.
