The current pandemic emergency has forced us once again to postpone the 10^th International Congress of Tidal Sedimentology, which for 40 years has been held every four years hosted by various countries around the world and which for the first time will be organized in Italy.

While waiting for a better international situation allowing to resume congress activities, hopefully in the spring of 2022, the organizing committee of Tidalites proposes a virtual symposium on October 5^th and 6^th 2021, sponsored by the Italian Geological Society.

The workshop will host key notes by six international geoscientists who will present some of the latest breakthroughs on the sedimentary dynamics of modern and ancient tidal environments. The international community is invited to join us at the pre-Tidalites Virtual Symposium, as we wait for Tidalites 2022 in Matera.
