Mirovia

Rodinia was surrounded by the superocean geologists are calling Mirovia (from 'mir', the Russian word for "world").

Mirovia (Rodinia)

The Mirovia may be essentially identical to, or the precursor of, the hypothesized Pan-African Ocean, which followed the rifting of Rodinia.

The global ocean of Mirovia, an ocean that surrounded Rodinia, started to shrink because the Pan-African ocean and Panthalassa were expanding.

Named global superoceans include Mirovia, which surrounded the supercontinent Rodinia, and Panthalassa, which surrounded the supercontinent Pangaea.

Geologic evidence suggests that the middle Neoproterozoic, the Cryogenian period, was an extreme ice age so intense that Mirovia may have been completely frozen to a depth of 2-km.

Inside the "V" was Panthalassa, outside of the "V" was the Pan-African Ocean and remnants of the Mirovia Ocean.

South China was bordered by Mirovia Ocean to the north, Siberia to the east, Australia to the west, and Laurentia to the south as shown here in the Rodinia paleogeography.
