Abstract

Abstract:

In this study, we conducted zircon trace element and whole-rock major element analyses on the Shangqimugan granites, and calculated the zircon saturation temperatures and titanium temperatures, which can unravel the temperatures of the source magma, and the formation environment of granite is further analyzed. Our zircon samples present typical igneous zircon REE left-inclining patterns. Besides, LREEs are obviously depleted and HREEs enriched. The samples have distinct negative Eu anomalies and positive Ce anomalies. The results indicate that the zircon saturation temperatures for the Shangqimugan granites are at 772-829 ℃ (average 800 ℃), which belong to high-temperature granite. The minimum Ti-in-zircon average temperature is 614 ℃, the maximum average temperature is 634 ℃, and the zircons were formed at 614-634 ℃ in the granites. Combining with zircon trace elements characteristics, the zircon saturation temperatures and the correlation between titanium temperature with Th/U and 10000/Hf, we suggested that the Shangqimugan granites were formed by delamination of the thickened lower lithosphere led by mantle underplating in the West Kunlun Orogen. During the magma fractionation, zircon has recrystallized and multiphase magma (melts-fluids) replenishment may have occurred. The heat source of magma was probably related to the asthenospheric upwelling (mantle underplating), which occurred during the post-collision intraplate extension at the end of Qiangtang-Tarim plate convergence along the Kangxiwar fault.

Key words: trace element, zircon saturation temperature, titanium temperature, Shangqimugan of WestKunlun
