Talc schist deposits from central Cameroon: Mineralogical and physico-chemical characterization

Talc schist deposits are reported in central Cameroon region, and different alteration zones were determined depending on differences related to the texture color of host rock. For purpose determining mineralogical physicochemical characteristics talc schist, a total 45 samples from sites studied collected analyzed using an array physico-chemical methods. mainly composed variable amount associated with plagioclase clay minerals. Three groups mineral association determined: i) small chlorite traces kaolinite, ii) high chlorite, iii) The have homogeneous grain-sizes classified as silty sand or sandy silt. occurrence Ni Cr schists consistent composition formed relation ultramafic rocks. genesis is due hydrothermal fluid circulation rocks, attested by S P.
