Vaalbara

Vaalbara was an Archean supercontinent consisting of the Kaapvaal Craton and the Pilbara Craton. E. S. Cheney derived the name from the last four letters of each craton's name. The two cratons consist of crust dating from 2. 7 to 3. 6 Gya, which would make Vaalbara one of Earth's earliest supercontinents.
