摘要
There are two period Mesoproterozoic rock-masses intruding in the Precambrian crystalline basement in Kusilafu area of the northern margin of western Kunlun. The early rock-mass is Kateleke,and age is 1 567 Ma.The late is Azibaledier,and age is 1 423 Ma. By systematic study of two rock-mass’s Isotopic age, Mineralogy, Petrochemistry, Trace elements and REE, the authors think that there are two obvious Mesoproterozoic magma-tectonic events in northern margin of western Kunlun. Two magmatic activities may provide new evidences of the ancient Tarim Plate’s consolidation-cracking and its cracking mode’s supplementary.
