The Karoo and Farrar provinces together comprise a major flood basalt province, parts of which are found in both South Africa and Antarctica. It formed just prior to the breakup of Gondwana about 183 million years ago; this timing corresponds to the Pliensbachian-Toarcian extinction. The total original volume of the flow, which extends over a distance in excess of 6000 km (4000 km in Antarctica alone), was in excess of 2.5 x 106 km³.
