Abstract:The majority of records regarding the Great Oxidation Events (GOE) are derived from the geochemical characteristics of sedimentary rocks, with minimal involvement of evidence from igneous rocks. However, the Th/U ratio of global arc magmatic rocks has successfully indicated two instances of the GOE, pioneering a new area of study using igneous rock geochemical indicators to explore GOE research. Arc magmatic rocks generally form through the melting of the overlying mantle wedge during subduction-induced dehydration of oceanic crust, exhibiting enrichment in heavy rare earth elements. Combining the results of studies on arc magmatic rocks, this paper explores whether TTG (Tonalite-Trondhjemite-Granodiorite) magmatic rocks from different periods can record GOE and what impact the formation of GOE has on TTG, especially considering that previous studies often overlooked this influence when considering the formation of TTG during and after the Great Oxidation Events. Through zircon geochronology, within the range of 2.45-2.20 Ga (Tectono-Magmatic Lull), this study demonstrates research on TTG rocks influenced by the addition of crustal material during different periods (2.43-2.18 Ga), including evidence from zircon Th/U ratios and zircon oxygen fugacity anomalies. This provides new evidence for exploring the impact of GOE on magmatic rocks at different depths.Research has demonstrated that the main and trace elements in TTG rocks from three distinct periods exhibit similar geochemical characteristics to high silica adakites. Additionally, the Great Oxidation Event (GOE) showcases a pattern of increasing and then decreasing oxygen isotope and oxygen fugacity changes throughout various periods of magmatic activity.Structural diagram of whole rock granite and trace elements of zircon suggests that TTG rocks were formed within an island arc environment situated along an oceanic subduction zone. This formation process is hypothesized to be the result of dehydration and melting of the subducted oceanic crust. Consequently, such processes lead to variances in the oxygen fugacity of TTG rocks.
