Lithology and environment
Primary lithology: | grading,bioturbation,fine,medium,ferruginous lithified sandy sandstone |
Lithology description: lithologic unit II is predominantly composed of sandstone, fine to granule in size, angular to rounded, moderate sorting and moderate porosity, feruginised and strongly associated with rootling. It is rarely intercalated with thin shale beds. The upper part of the sandstone body shows an upward coarsening sequence (3310m-3230m) compared to the underlying massive sandstone bed. The associated characteristics suggest a sandstone body deposited in a fluvial environment. | |
Environment: | fluvial indet. |
Taphonomy
Modes of preservation: | original sporopollenin |
Size of fossils: | microfossils |
