Riphean and Vendian of the USSR
Precambrian Research, 1981Abstract The Upper Proterozoic of the U.S.S.R. is subdivided into two chronostratigraphic units according to the officially-adopted stratigraphic scale: the Riphean, 1650 ± 50−650 ± Ma, comprising four subordinate subdivisions; and the Vendian, 650 ± Ma—Cambrian.

Vendian and Riphean rifting in NW Scotland
Journal of the Geological Society, 1995In the Neoproterozoic, NW Scotland was located in a tract of extending continental lithosphere that evolved into the eastern passive margin of Laurentia when Iapetus opened in the Vendian. On the NW Caledonian foreland, major rift events are inferred in the Riphean and Vendian, corresponding to the intra-Torridonian and sub-Cambrian unconformities ...
