| 词条 | Maud Rise |
| 释义 |
GeologyMaud Rise formed part of the south-eastern African large igneous province (LIP) which developed south of Africa {{Ma|100|94}} (Ma). This LIP first formed 140-122 Ma east of South Africa where the Mozambique Ridge is now located. There it reached a maximum extent around 120 Ma when the African-Antarctic spreading zone was located below its eastern flank. Astrid Ridge was possibly part of this LIP as well.[2] The LIP formation then continued intermittently until it finally reached its maximum extent south of South Africa 100 Ma. This volcanism ended 94 Ma after which sea-floor spreading divided the LIP into the Agulhas Plateau (south of South Africa), Northeast Georgia Rise (near South Georgia Island off South America), and Maud Rise.[2] See also
