Abstract: Tin and gold mineralisations are considered in the context of their geological setting in an area in the Rondonia Tin Province of the Amazon Region. Mineral investigation methods are outlined and maps illustrating the distribution of some anomalous target areas are provided. Preliminary controls are indicated. A possible anomalous xenothermal type of deposit, mineralogically correlatable to areas of similar mineralisation, is suggested.
