地球化学和Nd、Pb同位素研究表明,鞍山地区陈台沟花岗岩不是早期古老陆壳物质壳内再循环的产物,而是同时代亏损地幔提取物(变玄武质岩石)在短时间内发生再次熔融的结果,形成过程中受到古老陆壳物质的混合混染。3.15±Ga是鞍山地区地质演化过程的一个重要阶段,它使陈台沟花岗岩的长石Pb和全岩Pb发生再次均匀化。3.3Ga的花岗质岩石在鞍山弓长岭地区也有分布,它们来自于与陈台沟花岗岩类似的物源区,但形成条件可能并不完全相同。
Geochemical and Nd, Pb isotopic studies show that the Chentaogou granite in Anshan is not the product of the early recycle of the ancient continental crust, but the re-melting of the same-period depleted mantle extract (basaltic rocks) in a short period of time As a result, the formation process was mixed and contaminated with ancient continental crust material. 3.15 ± Ga is an important stage of geological evolution in Anshan area, which makes the feldspathic Pb and the whole rock Pb of the Chentaogou granite to homogenize again. The 3.3Ga granitic rocks are also distributed in Gongchangling, Anshan, which originated from similar source areas of the Chentaigou granite. However, the formation conditions may not be exactly the same.
