Period:
Permian
Province:
Moatize-Minjova Basin
Type Locality and Naming
Tete Province (Lower Zambezi Basin)
Lithology and Thickness
Comprised of gravel is either massive or crudely bedded, with a matrix composed of fine to coarse sand. The clasts are irregular and angular, mostly red-colored and granitic in composition, often with casts of potentially intrabasinal pelitic clasts. The transition to Arcosic sand is likely gradual, and there is weak or non-grading observed.
The Arcosic sand ranges from medium to very coarse, sometimes containing pebbles. Trough cross-beds are interbedded within the Arcosic sand, which itself ranges from medium to coarse, occasionally containing pebbles. Planar cross-beds are predominantly 10 cm to less than 1 m in size. Overlaps in the beds often show load casts marks. Additionally, there is Arcosic sand that is fine to medium-grained, featuring low-angle planar cross-stratification.
Lithology Pattern:
Coarse-grained sandstone

Fossils
Dadoxylon nicoli Seward
Age
Middle Permian (260) to Upper Permian (254). The recent palynological revision of the Matinde Fm has indicated that was deposited in the latest Permian, close to the Permian-Triassic boundary.
