Stratigraphy
Geological group: | Mogotuin Suite | ||||
Stratigraphy comments: Based on the mammalian fossil assemblage, the red beds are con
sidered to be Cenozoic. More detail and longer prospecting work for fossils in the area will provide rich mammalian fossil specimens. The application of magnetostratigraphy to the red beds with thickness over 30 meter will also give reasonable dating results of the fossiliferous red beds. |
Lithology and environment
Primary lithology: | red mudstone |
Secondary lithology: | fine sandstone |
Includes fossils? | Y |
Includes fossils? | Y |
Lithology description: The red beds consist of thick mudstone, intercalating sandstone and conglomerate layers. From the mudstone and fine sandstone, we found mammalian fossils. Caliche is abundantly developed in the mudstone. | |
Environment: | terrestrial indet. |
