1. A large continental block existed with oceanic crust subducting underneath it. 2. Kenn Reef is part of a submerged continental block , called the Kenn Plateau. 3. The subducting process ceases with the involvement of buoyant continental block . 4. Late Paleozoic, 251 million years ago, Chile belonged to the continental block called Gondwana. 5. Kenn Reef is located on part of a submerged continental block , called the Kenn Plateau. 6. A sphenochasm is a triangular gap of oceanic crust separating two continental blocks and converging to a point. 7. The orogenic belts present on continental blocks are classified into three different categories and have implications of interpreting geologic bodies. 8. The continent of Antarctica is divided into two continental blocks , separated by the Transantarctic Mountains of the West Antarctic Rift System. 9. It does not contain the abundant minerals of Kazakhstan and may have been a pre-existing continental block before the Kazakhstan Block was formed. 10. The Mekong basin is not normally considered a seismically active area as much of the basin is underlain by the relatively stable continental block .
