Stratigraphy
Formation:Sundvollen
Stratigraphic resolution:formation
Stratigraphy comments: "Sundvollen Formation. Late Wenlockian."
Lithology and environment
Primary lithology:gray siltstone
Secondary lithology:"cross stratification",red or brown sandstone
Lithology description: "Dark-gray siltstone associated with red sandstone and siltstone, with ripple marks, cross-laminations, and crack diapirs, and pseudo-nodules; carbonate concretions; fining upwards 'cyclothems'; tracks attributed to eurypterids have been found in the red siltstone."
Environment:fluvial indet.
Geology comments: "Turner (1974) interprets the Sundvollen Formation as representing meandering, braided streams on an alluvial, coastal plain, very close to sea level (minor marine incursions found). Indicated by Boucot and Janis (1983) to be possibly brackish-estuarine."
