西秦岭西段花岗岩浆作用与成矿OACSCDCSTPCD
The Granitoids Magmatism and Mineralization in West Section of the Western Qinling, NW China
对西秦岭北部花岗质岩体的岩石学、地球化学研究表明,花岗岩体的岩性主体为花岗闪长岩-二长花岗岩,属高钾钙碱系列,少数为钙碱系列；LA-ICPMS锆石U-Pb测年表明其形成时代介于216～264Ma,为中二叠世末至晚三叠世.江里沟、阿夷山和中川岩体属弱过铝质花岗岩(ACNK＞1.05),温泉岩体和德乌鲁岩体属准铝和弱过铝质花岗岩(ACNK=0.95～1.05)；花岗岩具有埃达克岩(Sr＞400×10-6,Yb＜2×10-6)或喜马拉雅型花岗岩(Sr＜…查看全部>>
Based on petrogeochemistry, the samples form intrusions in western Qinling mostly belong to high-K calc-alkalic series with a few scatter to calc-alkalic series. The study results in this essay also show that there exist adakite and Himalaya type granites in the northern edge of Western Qinling, and the Jian-glugou, Ayishan and Zhongchuan intrusions are similar to Himalaya type granite, and Ayishan pluton is similar to adakite based on the content of S…查看全部>>
