Summary
| Description |
English: From paper: Superb exposure (albeit inaccessible) of the lower to middle part of the SCF showing thick floodplain fluvial deposits (FA 2), composed of intercalated mudstone and thin sandstone beds. Changes in mudstone coloration from reddish to greenish suggest high frequency changes in oxidation conditions. Sandstone beds show sharp bases, sometimes erosive, and commonly wedge shape. White arrows point to evident wedging out of some of these beds. Few thicker, lenticular fluvial channels (Ch) also intercalate. In the background, the Río Tarde (whitish), the Posadas Basalt (dark grey) and the El Chacay (greenish) formations are observed. |
