Abstract
A temporary and drastic decrease in 34S/32S ratio of whole rock sulfide has been recognized at the suspected Permian/Triassic (P/Tr) boundary at Tenjinmaru in the Chichibu Terrane in eastern Shikoku, Japan, which is characterized by the occurrence of a carbonaceous black mudstone. The observed isotopic profile in the P/Tr section is in striking contrast in mode of 34S/32S excursion to that at the K/T boundary at Kawaruppu in eastern Hokkaido, Japan, and adds to significant geochemical constraint to the current arguments on the palaeoenvironmental changes during the time of terminal Permian mass extinction. -from Authors
