Abstract

Abstract

This article studies systematically the petrology and geochemistry of the volcanic rocks of Haidewula area, east Kunlun orogenic belt, Qinghai Province. Based on the section, isotopic dating and regional strata contrasting, it has determined that this suit of volcanic rocks should be Early Jurassic. These volcanic rocks are mainly basic and acid, showing typical "Bi-model" character of rifting, but lacking in intermediate rocks. The basic rocks have a higher alkali degree, while the acid rocks mainly belong to calc series. The volcanic rocks are formed in the rift tectonic environment, split from inner continent among the post orogeny.
