西昆仑山北坡新发现的其曼于特蛇绿混杂岩带所包含的主要岩性单位有:蛇纹岩(变辉橄岩)、橄榄辉石岩、层状辉长岩、辉长岩、辉绿岩席、枕状、块状、杏仁状玄武岩,与之共生的沉积岩为紫红色硅质岩、深灰色硅质岩、薄层灰岩等。本文就该蛇绿混杂岩带的地质、岩石学特征及主要岩石单元的年代学特征进行论述,并对其地质意义进行初步探讨。
The main lithologic units in the Mandette ophiolitic mélange newly discovered in the northern Kunlun Mountains are: serpentinite (gabbro), olivine pyroxene, layered gabbro, gabbro , Diabase mat, pillow-like, massive, almond-like basalts, and the symbiotic sedimentary rocks are fuchsine, dark gray silicalite and thin-layer limestone. In this paper, the geology and petrology of the ophiolitic melange belt and the chronology of the main rock units are discussed, and their geological significance is discussed.
