Geomorphology map of the marine and transitional terraces and raised shorelines of the Península Juan Mazía, Tierra Del Fuego. Straits of Magellan – Chile

This manuscript presents a detailed map (1:50,000) of the geomorphology of the marine and transitional terraces and raised shorelines linked to Holocene-Pleistocene (?) glacio-eustatic variations in Península Juan Mazía situated on the Segunda Angostura in the western area of the Straits of Magellan. The Main Map, centered on approximately 52° 40’ and 52°60’, was compiled through geomorphological survey in the field integrated with interpretation of aerial photographs and remote-sensing imagery. The survey has allowed mapping of a regular sequence of terraces and raised shorelines represented mainly by marine, and partially by transitional terraced deposits, located in four orders at the respective elevations of 18÷25 m, 6÷11 m, 3÷5 m and 1÷2 m above mean sea level. The Main Map also provides other features such as landforms and deposits, due to littoral, running water, glacial and wind processes.
