摘　　要：Objective The Bayingou ophiolitic Tianshan Mountains of melange is located in Northerm the southern Central Asian Orogenic Belt which is the largest accretionary oroger among the European, Siberian, Tarim and North Chine cratons. The Bayingou ophiolitic melange provide a critical geological record for unraveling regional tectonic histor） and testing different tectonic models. However, previous studies were mainly concentrated on geochronology, rock combination, structural feature and geochemistry ol ophiolite, with little attention to oceanic island basalts in the Bayingou ophiolitic melange. Therefore, in this study, we focus on pillow basalts from ophiolitic melange.Objective The Bayingou ophiolitic Tianshan Mountains of melange is located in Northerm the southern Central Asian Orogenic Belt which is the largest accretionary oroger among the European, Siberian, Tarim and North Chine cratons.
