Laurentia-Gondwana Connections Before Pangea, Tema 336Víctor A. Ramos, J. Duncan Keppie Geological Society of America, 1999 M01 1 - 276 páginas Explores the tectonics interaction among the exotic terrians between Laurentia and Southwest Gondwana. The authors reveal data that sheds light on pre-Pangea connections between Laurentia and Southwest Gondwana. These data concern the presence of Ollenelus and associated fauna in the Precordillera of central Western South America; the common early Paleozoic paleomagnetic data, the presence of a large early Paleozoic carbo nate platform distinct from the Southwest Gondwanan clastic platforms associated with glacial deposits, and the exotic nature of the Grenville basement of this platform. |
