Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, and hardening retarder in Portland cement.
In Tanzania Anhydrite Gypsum occur in two geological setting. Those are Coastal basins of Jurassic sediments deposit from Indian Ocean and Buga deposits of the Inland basin in East African rift valley.
Buga deposits concentrated in North-eastern and Central of Tanzania but they are not good in quality compared to Coastal deposit. They are less than 70% purity of Gypsum but used in cement and chalk productions and exported to Kenya for soil conditioning. These deposits include Makanya in Same, Mkomazi in Lushoto, Itigi in Manyoni, Msagali in Mpwapwa and the Pangani river basin deposit.
Coastal deposits concentrated in the Jurassic marine sediments in near shore region between Kilwa and Lindi. They form quality Gypsum beds, of as much as 96% of Gypsum which alternating with shale and limestone.
Gypsum rocks are outcropping in several places in the cores of two Parallel anticline structures in Pindiro-Mkomore-Mbaru complex. This is diapiric rock salt domes capped by Gypsum and Anhydrite arc at least 150 metres in thickness but even as much as over 280m (according to the BP-shell. co. ltd Boreholes).
Three deposit found thus are Pindiro (Makanganga-kilanjelanje), Mbaru (Hotel tatu) and Mkomore. This quality Gypsum is suitable for variety of uses includes cement production, Gypsum board, Gypsum powder and ceramics production.
Gypsum in Tanzania mined in small scale to feed the Portland cement and Gypsum powder industry but the market is enormous in East and Central Africa. Portland cement industry growing in East and Central Africa due to expansion of infrastructure and building construction industry and because of Indian Ocean, shipping of Gypsum to Asian countries at lowest cost is possible.
