【摘要】The Jialuhe basic-intermediate intrusion is situated inside of the Xiangjia''nanshan granitic batholith at the eastern end of the East Kunlun orogenic belt. It is mainly composed of hornblende gabbro and quartz diorite. LA —ICP— MS zircon U —Pb dating showed that the Jialuhe intrusion was emplaced at 220 Ma. The rocks have low SiO2 (47. 91%-58. 92%) and Al2O3 (15. 54 %-18. 35%) contents, low A/CNK(0. 70-0. 90) ratios, high Mg^#(46- 61), and display metaluminous middle-K calc - alkaline affinities. 【总页数】6页(P.40-45)
