Mulanje


Spectacular mountainous area rising to some 3000 m from Palombe Plain. (750 m) and extending over 640 km².

There are several areas of bauxitization on Mlanje but the only potentially economic ones are on the Lichenya Plateau in the SW of the complex. Reserves of 50-60 million tons averaging 43% Al₂O₃, 14% Fe₂O₃ and 17% free quartz ave been proved (Garson & Walshaw 1969).

Important 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.
