摘要:
对甘肃北山大豁落南地区花岗闪长岩进行了LA-ICP-MS锆石U-Pb测年及主量和微量元素地球化学分析。结果表明，花岗闪长岩的结晶年龄为259.7±1.5Ma。花岗闪长岩SiO2含量介于63.10%~69.69%之间，Al2O3介于14.86%~15.48%之间，平均15.21%，MgO含量为0.96%~3.59%，平均2.69%，岩石强烈富集轻稀土元素，(La/Yb)N为18.60~50.91，具弱Eu异常(δEu=0.83~1.06)，高Sr(454×10-6~862×10-6)、高Sr/Y值(Sr/Y=44.95~60.35)，具有埃达克岩的地球化学特征。花岗闪长岩富钾、贫钠，具有较高的Cr、Ni含量和Mg#(50.31~66.75)值，结合区域地质背景，认为花岗闪长岩是碰撞后板内热隆伸展环境壳幔交互作用的产物，暗示晚古生代北山地区地壳为垂向增生，与以天山为主的中亚造山带大范围存在的二叠纪与幔源岩浆有关的花岗岩是同期构造岩浆事件的产物。
Abstract:This paper reports LA-ICP-MS zircon U-Pb ages and whole rock major and trace elements from granodiorite in southern Dahuoluo area of the Beishan region. Magma zircons from granodiorite yielded a weighted 206Pb/238U mean age of 259.7±1.5Ma. Granodiorite is characterized by SiO2 ranging from 63.10% to 69.69%, Al2O3 ranging from 14.86% to 15.48%, 15.21% on average, MgO ranging form 0.96%~3.59%, 2.69% on average, strong enrichment of LREE, and (La/Yb)N values ranging from 18.60 to 50.91. In addition, Eu anomaly is not obvious, with Eu/Eu* values ranging from 0.83 to 1.06, Sr content is high (454×10-6~862×10-6) and Sr/Y ratio is 44.95~60.35, rocks show geochemical characteristics of adakite. Granodiorite is enriched in K and depleted in Na, and has high Cr, Ni and Mg#(50.31~66.75). Combined with regional geological background, the authors hold that granodiorite was formed after the collision, as a product of both intraplate thermal upwelling extension and crust-mantle interaction. It is suggested that, in Late Paleozoic, the crust in Beishan area was in vertical increment, and the granites associated with the Permian and mantle-derived magmas were in the form of synchronic tectonic magmatic events.
