| 摘 要： | 钢屯超单元①花岗岩位于燕山台褶带山海关台拱与辽西台陷的交接部位，是燕山期构造岩浆活动的产物。钢屯超单元是在同源岩浆由粗粒→细粒，酸性→超酸性，碱性→过碱性演化基础上形成的一种Ｓ型花岗岩，这种演化是本区Ｍｏ，Ｃｕ，Ｐｂ，Ｚｎ多金属矿形成的主要原因。

| Abstract: | Gangtun ultra unit granite occurred in the joint area of Sanhaiguan platform uprise and West Liaoning platform subside of Yanshanian platform fold belt,which was resulted from tectonomagmatic activities. It is a S type granite which the comagma evoluted from coarse to fine granular,from acid to ultra acid,from alkalinity to peralkalinity ,which the evolution resulting in the ore forming of Mo,Cu,Pb,Zn. |
