Description

In recent years, a controversy arose on whether a large ocean, called Cymene, existed between the Amazon ian craton and the Rio de la Plata / Congo-Sao Francisco craton s in the late Ediacaran. Comparison of the available reliable Paleomagnetic poles from the latter two craton s, West Africa and Lauren tia for the interval 615-560 Ma suggests that by ca. 575 Ma a large ocean existed between Lauren tia-Amazon ia-West Africa on one side and Río de la Plata and Congo-Sao Francisco on the other. This conclusion is still valid whether the "high latitude" or the "low latitude" option is chosen for Lauren tia. However, Paleomagnetic data from the proper Amazon ia are needed for definite conclusions
