abstract = {The Toarcian lacustrine deposits of the Sichuan Basin (China) are represented  mainly  by  silty  marlstones  and  bivalve-rich  limestones  disposed  in  decametric-scale  thickening  upwards  sequences.  Den-se  accumulations  of  bivalve  shells  are  related  to  episodes  of  mass  mortality  under  oxygen  depleted  conditions  in  the  bottom  waters.  The geochemical detrital proxies indicate a climatic turnover during the Toarcian.  The lower part of the Toarcian succession is characte-rized by high values of Zr/Rb and Sr/Cu that point to warm and arid conditions, whereas the upper part is characterized by low values of Zr/Rb  and  Sr/Cu  and  enhanced  C-value  related  to  relatively  more  humid conditions},
