摘　　要：铜石岩体就位于燕山早期 ,有五次脉动侵入活动 ,相应地可建立五个单元 ,归并为铜石超单元 ;岩浆末期形成细晶岩、霏细岩 ,热膨胀形成隐爆角砾岩、侵入角砾岩及沉陷角砾岩等。Tongshi complex emplaced in early Yanshan period. It experienced five pulsatory intrusive activities, which accordingly formed five units, and they belong to Tongshi superunit. Rhenopalites and eurite formed at the end of magmatic period, and cryptoexplosive breccia, intrusive breccia and sunk breccia formed by heat expansion. Tongshi complex have some characteristics of abyssmal multiple granites.
