| Summary: | The 6th map of the Coastal Atlas of the Strait of Magellan (1:50,000 scale) refers to sheets 84 and 101 of the Chilean I.G.M., and was made using the preliminary cartography by E.NA.P. (Empresa Nacional de Petroleo) and the Chilean I.G.M., aerial photos by S.A.F. (Servicio Aerofotogrammetrico Fuerza Aerea de Chile) and T.M. and M.S.S. Landsat satellite images. This research is aimed mainly at locating and mapping the marine and transitional terraces in Patagonia, along the eastern coasts of the Strait of Magellan, between Punta Arenas and Cabo Froward. Methodologicaly, we followed both the criteria of several more recent cartographic works produced by Programma Nazionale Ricerche in Antartide (Magellan Project), as well as the general criteria internationally adopted in coastal geological cartography. The coastal cartography of Quaternary deposits in the area south of Punta arenas (Tierra del Fuego - Strait of Magellan - Chile) is part of a wider ongoing research program that started in 1991 on the recent evolution of the Strait of Magellan. To this purpose, within the Programma Nazionale di Ricerche in Antartide (P.N.R.A.) (National Research Programme in Antarctica), 3 campaigns were carried out on land. The first was in 1991 and dealt with the sedimentology and geology of coastal Pleisto-Holocene deposits, while the second and the third, in 1994 and 2003 that is after the cartographic and geomorphological data had been processed, were intended as a check of the cartography of the old coastlines and postglacial, Quaternary, prevalently marine deposits. Moreover, the study also involves the the project RAS-PVS (Regione Autonoma Sardegna - Paesi in Via di Sviluppo - Cartografia Geologico - Morfologica delle Coste dello Stretto di Magellano). Among the objectives that developed during the research is the publication of an Atlas of the coasts of the Strait of Magellan on geological and geomorphological elements, prevalently Holocenic, that can be useful to formulate an evolutionary hypothesis of the Strait in very ... |
