Tectonic and paleoenvironmental significance of the Paleogene coal seams of Estancia La Correntina, Fuegian Andes
The continental sedimentary coaly outcrop of Estancia La Correntina, San Pablo River (54° 33' 01″ S, 64° 00' 20″ W), is described. The palynological assemblage compare closely with the similar one described from the Sloggett Formation, and is referred to the late Eocene-early Oligocene. Po...

Sumario: | The continental sedimentary coaly outcrop of Estancia La Correntina, San Pablo River (54° 33' 01″ S, 64° 00' 20″ W), is described. The palynological assemblage compare closely with the similar one described from the Sloggett Formation, and is referred to the late Eocene-early Oligocene. Podocarpaceae and Fagaceae are the most abundant forms. Pteridophyta are subordinate. The palynological assemblage would probably reflect a lacustrine or swampy environment, with regular levels of moisture and a temperate climate. Correlations between Estancia La Correntina and Bahía Sloggett outcrops support a NNW trending tectonic corridor, developed on pre-Paleogene units that controlled the deposition of continental sequences during the Eocene/ Oligocene in the Fueguian Cordillera. © 2004 Asociación Geológica Argentina. |
