Bauxite deposits in the Usambara Mountains of north eastern Tanzania occur as remnants of residual deposits on two geomorphologically related plateaus of Mabughai-Mlomboza and Kidundai at MagambaAbstract. According to field studies of the Pugu Hill kaolin deposit and mineralogical investigations (X-ray, SEM), two main types of Miocene sandstones are distinguished: (i) clayey-silty kaolinitic sandstones with stacks of idiomorphic pseudohexagonal kaolinite crystals; (ii) massive clayey-silty kaolinitic sandstones with Mineralogy and genesis of the Pugu Hill kaolin deposit, Tanzania Clay

Several Li-bearing clay deposits (Table 1) have been explored (Andrews et al., 2020). Many Li-bearing clay mineral resources have been discovered in specific regions in China and Europe. Thus, Li extraction from Li-bearing clay minerals could ensure the Li supply and expand the Li market (Malhi, 2018). The intense exploration and processing yGold: The majority of the deposits are lode‐type associated with the Mwembeshi shear Zone.
