Abstract

Based on the investigations of 48 species of fossil spores and pollen referred to 31 genera found from the Upper Triassic Yongping and Wayaopu Formations in T uweihe region of northern Shaanxi, the Late Triassic palynoflora in the region was established in this paper. In accordance with the character of the palynoflora, the Late Triassic paleoecological environment in the region was discussed. The relation b etween the origin of petroleum and coal and the environment was involved. The re sults of this study confirm that the lacustrine depositional environments under warm/h ot and humid/wet climatic conditions might be favorable for the origin of petroleum, and the swamp/marsh depositional environments under warm/hot and humid/wet clima tic conditions might be favorable for the origin of coal.
