摘要

Well-preserved stratigraphic sequences composed of radiolarian chert and basalt were found in Pha Som metamorphic complex in Nan suture zone, northern

Thailand

. Bedded chert contains Follicucullus porrectus, fossils from late Middle Permian to early Late Permian. These cherts have high SiO₂(>92.5%), low Al/(Al+Fe+Mn) ratio (0.51 on average), and high Ce/Ce ratio(1.14 on average). These geochemical characteristics mentioned above indicate that the cherts deposited on continental margins.
