摘      要：This paper presents organic geochemical evidence pointing to the occurrence of wildfire events at the Triassic-Jurassic boundary in Central *** studied outcrop section(the Kamarmacheh Kuh section)is comprised of the Upper Triassic Nayband Formation which passes conformably into the Lower Jurassic Ab-e-Haji Formation with no sharp *** petrographical studies reveal a higher concentration of semi-fusinite macerals and microscopic charcoal at the boundary between studied *** observation can be an evidence for widespread wildfire events at the Triassic-Jurassic boundary of the studied *** these fires,vast areas of land were exposed for erosion and large volumes of clastic sediments were provided due to increased *** agrees well with previous sedimentological and stratigraphical studies suggesting a major change in the depositional conditions from marine to non-marine at the Triassic-Jurassic boundary of the Tabas *** findings can have important implications about paleo-depositional settings of the studied formations and the nature of the associated organic matter.
