Abstract

The Magallanes Basin (Figure 1) is a retro-arc foreland basin (Suarez and Pettigrew, 1979; Dalziel, 1981; Wilson, 1991) and the sedimentary sequence (Figure 2) preserved in the Andean fold-and-thrust belt reflects both the early extensional phase of basin evolution and the subsequent uplift associated with Andean orogenesis. In the latest Jurassic, extension associated with the initial breakup of southern Gondwana (Bruhn et al., 1979; Gust et al., 1985; Pankurst et al., 2000) culminated in the development of an oceanic backarc basin referred to as the Rocas Verdes Basin (Katz, 1963). Ophiolitic rocks exposed in the Cordillera Sarmiento, south and west of Parque Nacional Torres del Paine, represent the obducted remains of the floor of this backarc basin.
