Numerical modelling of tectonically driven river dynamics and deposition in an upland incised valley... In continental environment, sediment mobilisation, dispersion and deposition are mainly controlled by mass gravity and stream-flow processes. Alluvial sedimentary systems have an important economic value because of their capacity to host mineral resources. In the Hamersley Province, alluvial iron deposits (including the well-known Detrital Iron Deposits and Channel Iron Deposits) play an increasing role on the commodity market. Alluvial deposits exploration is challenging and generally involves geomorphologic and stratigraphic field studies, as well as expensive exploratory surface sampling and drilling. We applied a new surface processes modelling technique to investigate iron rich material - i.e. the erosion product of bedded iron formations - dispersion in the Hamersley Province. LECODE is a 3D-parallel surface processes forward modelling code designed to compute surface flow and..
