摘要
Based on the recent geological investigation, the authors 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. The plant growth was strongly influenced by the magamonsoon developing during the Late Triassic.
