of Continental Drift Theory: radiometric dating methods developed in the period have facilitated correlating the rock from different continents across. the vast The belt of ancient rocks of 2,000 million years Brazil coast matches with those from western The earliest marine deposits along the coastline South America and Africa are of the Jurassic age. This that the ocean did not exist prior to that time. statement I is correct. Gondawana system of sediments from India is to have its counterparts in six different of the Southern Hemisphere. At the base, system has thick tillite indicating extensive and glaciation. Counterparts of this succession found in Africa, Falkland Island, Madagascar, and Australia. Overall resemblance of the sediments clearly demonstrates that landmasses had remarkably similar histories. The tillite provides unambiguous evidence of and also of drifting of continents. Hence, II is correct. occurrence of rich placer deposits of gold in the coast and the absolute absence of source rock in region is an amazing fact. The gold bearing veins are Brazil and it is obvious that the gold deposits of the are derived from the Brazil plateau when the two lay side by side. Hence, statement III is
