摘要:
铜山岭花岗岩具有贫硅、富铁镁钙、弱到中等铕负异常和K2O/Na2O﹥1的特点，属高钾钙碱性岩石；花岗岩的 ISr值（0.71060~0.71124）和εSr(t) 值（77.6~81.0）相对较小，δ18O值（8.62‰~9.67‰）较低；TDM年龄（1226~1536Ma）偏小，εNd(t)值（-7.1~-5.2）相对较高；花岗岩中发育壳幔混合的镁铁质微粒包体。这些特征表明该岩体具有壳幔混合花岗岩的性质。岩体 SHRIMP锆石UPb年龄为149±4Ma，属于燕山中期晚阶段构造岩浆活动的产物。
Abstract:
The Tongshanling granite is poor in silicon and rich in iron, magnesium and calcium, belonging to highpotassium calcalkaline series with weak to intermediate negative Eu anomalies and K2O/Na2O>1. New SHRIMP zircon UPb dating results yield a 238U/206Pb age of 149±4Ma, representing the crystallization age of the intrusion. The Tongshanling granitoids were formed during the stage of Middle Yanshanian tectonomagmatic events. Compared with regional other counterparts, these granitiods have relatively low ISr (0.71060～0.71124), εSr(t) (77.6～81.0) and δ18O (8.62‰～9.67‰) values, spanning εNd(t) and TDM ranges from -7.1 to -5.2 and from 1226 to 1536Ma, respectively. Besides, small mafic inclusions can be found in the granite body. Combined geological observations and geochemical data suggest that the Tongshanling granitoids were derived from a mixture between juvenile mantlederived materials and the ancient crust.
