Other applications are*-as filler material, smoke suppressant- in plastics, a -reinforcing agent in neoprene* rubber, a drying agent, and calm retention in floods. In addition, high purity magnesium wbonate is used as anti-acid and as an additive in table salt to keep it free flowing (Noetstrlller, 1988), Magnesium carbonate, most often referred to as 'chalk', is used in rock climbii as a drying agent for hmds. \ Magmesite deposits in Ethiopia wesite is found with dolomitic marble in Kenticha (Adoh Belt), as white, fine to medium grained crystalline rock. lt occurs -as linear belts extending for tens of kilometers. It is mainly associated with graphite schist. The width of the occurrence varies from few meters to about 50 m. Other occurrences of magmite me reported in H m (k Jak, Kunni), Sidamo, Moyale, WoIlega and .Assom in close 'on with basic and ultrabasic EGki rocks as yeins; ,Systematic e=n activities are required to assess the ecummic :potential of the magnesite mmmnces.
