Crustal growth of the Antarctic Peninsula by accretion, magmatism and extension

摘要: A subduction-accretion model incorporating new geophysical data is presented to explain the geology of Antarctic Peninsula from late Palaeozoic Cenozoic time. According model, peninsula consists overlapping accretionary, magmatic and extensional regimes that were diachronous across have built crust its present form. The crust, which contains a small proportion sialic basement, was mainly formed by accretionary processes modified shape extension. Gondwanide Orogeny for interpreted in terms processes.
