Stratigraphy
Lithology and environment
Primary lithology: | hematitic,intraclastic,red argillaceous mudstone |
Secondary lithology: | white sandstone |
Includes fossils? | Y |
Lithology description: "a red mudstone" with "pink hematite-rich clay clasts" that "probably represent 'rip-ups' associated with fluvial or fluviodeltaic sedimentation." "The fossiliferous horizon is approximately 1.5 m thick and is sandwiched between thin (0.15 m) white fissile siltstone layers" | |
Environment: | fluvial-deltaic indet. |
Geology comments: "may represent a lacustrine shoreface environment...some input by fluvial or lacustrine deltaic sedimentation" |
