Stratigraphy
Formation: | Maraldi Sandstone | ||||
Local section: | Torrente Meduna | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Miocene Torento-Meduna sequence unconformably overlies the Eocene Clauzetto Flysch (Flysch di Clauzetto) and is composed of Preplans Sandstone, Zouf marl, Rugo Mizza Sandstone, San Martino Calcarenite, Torrente Meduna Siltstone, Maraldi Sandstone, Bier Puddingstone, and Montello Conglomerate. Thickness of the Maraldi Sandstone is approximately 220 m. Sample 18 is from the uppermost part of the Maraldi Sandstone |
Lithology and environment
Primary lithology: | very fine,fine,yellow sandstone |
Includes fossils? | Y |
Lithology description: Maraldi Sandstone "consists of fine to very fine-grained, yellowish sandstone, thickneneing upward, alternating with darker, micaceous silty marl forming beds of various thickness". | |
Environment: | prodelta |
Geology comments: "In the absence of age-diagnostic species, a Tortonian age was inferred on the basis of stratigraphic position". |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Collection methods: | bulk,field collection |
Collection size: | 48 specimens |
Rock censused: | 30 cm3 (volume) |
Reason for describing collection: | paleoecologic analysis |
Collection method comments: Based on single bulk samples, about 30 cubic centimetres each. Grain size data also provided. | |
Taxonomic list comments:In enterers opinion the taxonomic list is representative of molluscan taxa, however no non-mollusca taxa are detailed. |
