Stratigraphy
| Formation: | Gatuncillo | ||||
| Local section: | Rio Gatuncillo | ||||
| Regional section: | Rio Agua Sucia | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Calcareous Mudstone. Exposures within the Rio Agua Suica b asin expose mudstone, siltstone, and sandstone. Mudstone and sandstone are more prevelant in the southeastern part of rte basin, sandstone in the northwestern part. Sandstone is medium-grained, poorly sorted, and contains much carboniferous debris. Limestone is not common, although algal and foraminiferal limestone is present. | |||||
