The Xueshan Formation is a set of red coarse clastic deposit of land facies consisting mainly of lithic sandstone, pebbled sandstone, conglomerate, intercalated with siltstone and mudstone. It is distributed in the eastern part of north Qiangtang Basin, and overlies conformably the Suowa Formation bearing marine fossils. It is very difficult to find valuable fossils from the Xueshan Formation excepting rare bivalve fragments and prints.We collected a few spore and pollen samples from the middle part of the Xueshan Formation in Tuonamulematianbao section, Shuanghu, in 1997, when we made geological survey for petroleum and nature gas. Some fossils of spore and pollen were obtained from these samples. They are: Cyathidites minor, Toroisporis sp .., Todisporites minor, Lygodiumsporites subsimplex, Cicatricosisporites ludbrooki, C. sp ., Psophosphaera sp ., Chasmatosporites minor, Classopollis annulatus, C. clssoiddes, C. minor, Cerebrropollenites carlylensis, Callialasporites dampieri, Quadraeculina anellaeformis, Pseudopicea variabiliformis. |
