The Tarim Large Igneous Province (TLIP), as a major igneous province in China, has long been a focus of geological research due to its complex rock assemblages and genetic mechanisms. This study investigates the Permian mafic dikes (diabase and sillite) in the Puchang area of the TLIP, combining zircon U-Pb geochronology, major-trace element geochemistry, and Sr-Nd-Hf isotopic analyses to reveal their petrogenesis and tectonic evolutionary significance. Zircon dating results show that the weight
