Tundulu Complex
A carbonatite complex in southeastern Malawi intruded during the late Jurassic to early Cretaceous over three episodes. During the first and second episodes, the major rock types were calcite carbonatites, ankerite carbonatites, and apatite carbonatites. Host rocks are nepheline syenite, sövite and ijoite.
NOTE on the mineral list: The three listed (Ca-)REE carbonates are all Ce-dominant, even though the abstract of Ngwenya (1994) erroneously suggests La-dominance (compare Table 3 in the paper).
The complex has been prospected for pyrochlore, rare earth minerals, apatite, barite and Fe and Mn ores (Garson 1962). Over 800000 tons of rock yielding over 20% P2O5 has been proved on Nathace Hill from the complex.

Mineralization age: Early/Lower Cretaceous : 140 Ma to 126 MaImportant note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
