Abstract

The Permian-Triassic boundary mass extinction affected the carbonate platforms and its critical condition resulted in deposition of only non-skeletal sediments as microbial deposits and fan-shaped aragonitic bodies that directly precipitated on seafloor. These sediments usually precipitated in shallow equatorial platform in which physiochemical condition was suitable. The SHAHREZA section in south of Isfahan is one of the exclusive section that recorded sedimentation continuously in Permian to Triassic intervals. Moreover the EARLY TRIASSIC SEDIMENTS in this section have shown abnormal sedimentation and sea water composition. Growth of aragonite fibers in the form of fans and associated in domes shows the evidence that changed by Permian-Triassic mass extinction mechanisms. These fibers have grown synsedimentary in seafloor and formed large domes. These evidences have shown that aragonite has been the original carbonate mineralogy when the ambient water was supersaturated in respect to calcium carbonate.
