Middle Karoo Fm
Type Locality and Naming
Metangula Basin (Mozambique). Noted as a lithostratigraphic division within the Karoo-aged Metangula Basin, which straddles the border between Mozambique and Tanzania. In the provided stratigraphic columns, it is utilized as a broad formational or sequence descriptor (alongside the "Lower Karoo") for the deeper, older sediments in this specific graben.

Lithology and Thickness
Based on the regional stratigraphic cross-sections, the "Middle Karoo" of the Metangula Basin is a terrestrial sequence containing notable coal seams (indicated by solid black bands in the stratigraphic column) interbedded with mudstones and arenaceous (sandy) clastics.
Relationships and Distribution
Lower contact
Conformably overlies the basal Lower Karoo Fm within the Metangula Basin
Upper contact
Conformably overlain by the Monte Lilonga Fm.
Regional extent
Geographically restricted to the Metangula Basin in northern Mozambique. Likely correlates with the Ecca Gr equivalents of the eastern African rift basins, given its stratigraphic position and lithological content.
