Lithology and environment
| Primary lithology: | red siltstone | ||
| Lithology description: The sediments of the 3V sequence, and that of most of the Pautut area, are represented mostly as coarsening upward cycles. Tha vary randomly between 2 and 6 meters in thickness. The basal unit of a cycle typically is a thin, not more than 2 cm thick, and horizontally bedded white clay or siltstone sometimes containing closely packed, wood impressions all oriented with a singular lineation. | |||
| Environment: | deltaic indet. | Tectonic setting: | rift |
| Geology comments: This cycle appears to represent a depositional position intermediate between the near shore prodelta and the more basinward bay sediments. These cycles have a thickness and color closer resembling that of teh PRP cycle but with a slightly differnet fossil content. Marine organisms and conifer stems and cones are present but few in number. The angiosperm leaf species represented are the same riparian species as in the near shore cycles but with a greater number of specimens than in those cycles. | |||
