Outcrop distribution

The Rencontre Formation (locally pronounced Rown-Counter) is a geological formation just below the Cambrian-Ediacaran boundary in Newfoundland, deposited in a fault-bounded enclosed basin. U-Pb dates obtained just below its base give a maximum age of 552 ± 3 million years ago

It is subdivided into five depositional phases, with two subsequent phases in a seven-phase series corresponding to the overlying Chapel Island Formation (900 m thick in this basin) and Random Formation (250 m thick in this basin).
