| 摘 要： | 通过岩石化学、微量元素地球化学、稀土元素地球化学、铅同位素地球化学特征研究表明， 铜山石英闪长岩、花岗闪长岩、二长花岗岩是同一岩浆源同一时期（ 燕山早期） 三个侵入阶段的产物， 铜山岩体幔壳同熔型的复式岩体， 属太平洋钙碱性岩石系列。铜山铜矿床的形成与铜山复式岩体的岩浆充分演化分异有关。

| Abstract: | Study on the petrochmical,trace element chemical,REE geochemical and Pb isotopic geochemical characteristics of the Tongshan intrusive indicates that the quartz diorite,granodiorite and adamellite are products of three stages of the same period(early Yanshanian)from only one magmatic source.The Tongshan intrusive is a composite one of mantle-crust syntectic type and belongs to Pacific type calc-alkali rock series.The formation of the Tongshan copper deposit is related to the complete magmatic evolution and differentiation of the Tongshan composite intrusive. |
