  • Abundant plant fossils were found in the Upper Triassic Xujiahe Formation outcropped in the Western margin of Sichuan Basin. Based on the recent geological investigation，we discovered wellpreserved fossil woods with clear growth rings, which indicated that warm climate developed during the Xujiahe Formation deposited. The growth rings of fossil wood showed seasonal fluctuations. It was thought that the climate alternation was closely related to the megamonsoon which was prevalent from the Permian to the Triassic. Average sensitivity of the tree rings of fossil woods was calculated to less than 0.3,which showed the balanced water supply. The plant growth was strongly influenced by the magamonsoon developing during the Late Triassic.

Abstract: Abundant plant fossils were found in the Upper Triassic Xujiahe Formation outcropped in the Western margin of Sichuan Basin. Based on the recent geological investigation，we discovered wellpreserved fossil woods with clear growth rings, which indicated that warm climate developed during the Xujiahe Formation deposited. The growth rings of fossil wood showed seasonal fluctuations. It was thought that the climate alternation was closely related to the megamonsoon which was prevalent from the Permian to the Triassic. Average sensitivity of the tree rings of fossil woods was calculated to less than 0.3,which showed the balanced water supply. The plant growth was strongly influenced by the magamonsoon developing during the Late Triassic.
