摘要
五垛山复式岩基位于北秦岭构造带东段,地处朱阳关—夏馆断裂和乔端—瓦穴子断裂之间,整体呈NWW向展布,由多个岩体复合组成,具多期次岩浆活动特征,岩性主要为黑云母二长花岗岩。本文在其解体出来的石门序列和五垛山序列中,采集5件样品进行了锆石U-Pb年龄值测定。测定结果对该区岩浆活动、构造背景及区域构造演化、地层时代确定等具有一定的地质意义。
Wu Duoshan compound batholith is located between Zhuyangguan-Xiaguan fault and Qiaoduan-Waxuezi fault in the eastern North Qinling orogenic belt.Generally,the batholith extends in NWW direction and consists of several intrusive bodies characteristic of multi-intrusion.Now it is divided into several series and five samples are collected from series Shiman and Wuduoshan and the zircon U-Pb age dated.The result is significant to determine the magmatic activity,tectonic setting,regional tectonic evolution and stratigraphic time.
