东准噶尔地区晚古生代向南增生:来自A型花岗岩的启示
Late Paleozoic south-ward accretionary polarity of the eastern Junggar orogenic belt: insight from the Dajiashan and other A-type granites
-
摘要: 大加山碱性花岗岩位于卡拉美丽-哈尔里克花岗岩带的中段,主要为中细粒钠铁闪石花岗岩.大加山碱性花岗岩锆石LA-ICPMS年龄为284±1Ma.该花岗岩具有富碱(A/CNK1.2.这些说明大加山岩体为二叠纪A2型花岗岩.东准噶尔和天山地区各花岗岩带年龄有向南为逐渐年轻的趋势,这与新疆北部由北向南增生的方向一致.因此,可能是侧向增生与垂向增生均表现出向南增生极性.
