Stratigraphy
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: The coastal plain of Rio Grande do Sul have developed the lateral juxtaposition of a depositional system of alluvial fans, and four systems of lagoon-barrier (Villwock & Tomazelli, 1995). The four lagoon-barrier systems were formed starting from four transgressive-regressive events: systems I, II and III of Pleistocene age and System IV of Holocene age. The fossils studied are associated with the deposits of the Lagoon-Barrier System III. These fossils are rolled and collected at the beach. |
Lithology and environment
Primary lithology: | not reported |
Environment: | lagoonal |
Geology comments: The fossils present dark coloration, high density and carbonate cement, suggesting reworking by the marine ambient (Lopes et al., 2001). After the deposition in lagoonal ambient (probably the Lagoon III), posterior to the fossilization process, they were reworked and cemented by calcium carbonate in a marine shore environment and preserved in sandstones and carbonate in the parcels and submerged banks (foreshore and continental platform). Later, they were exposed to weathering, when there was recrystalization of the carbonate in fresh water. The fossils presently rolled in he coastline are from several source-areas that were formed of old atrand lines, and transported due to the action of present hydrodynamic processes (Buchmann, 1994, 2002) |
