The volcanogenic claystone in the Permian-Triassic boundary plays a significant role in understanding the volcanism and provenance in Yangtze Plate, which is widely distributed in South China. This paper reports zircon U-Pb ages determined by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) along with Hf isotopes, whole-rock elemental and X-ray diffraction for the samples of claystone in the lower Feixianguan Formation along Cilinbao section. The microscopic characteristics, X-ray diffraction and major elements analysis show that the claystone contains illites and small amounts of calcite and quartz. The detrital zircon age data exhibit a wide range, varying from 2 615 Ma to 246 Ma and concentrated on 2 615~2 383, 1 868~1 328, 1 186~778 and 430~246 Ma, with a~250 Ma peak value. Combined with the in-situ zircon Hf isotope, the authors detected that the zircon characteristics are similar to those in Qinling Mountain, Permian-Triassic boundary sections in South China and Emeishan large igneous province. Indeed, geochemical compositions of the claystone are characterized by relative enrichment of Zr, Hf, Th, Cr, Co and Ti, similar to features around Permian-Triassic boundary sections in South China and Emeishan basalt. Combined with tectonic setting of the end of Permian and detrital zircons, the authors hold that the claystone around the Permian-Trassic boundary along the Cilinbao section at Majiaoba was derived from Qinling Mountain, Longmenshan Islands, volcanism and Emeishan large igneous province.
