in low energy pools at the tail-end of bars or between riffles shutes; or, 3. infilling voids below the surface of cobble-gravel bars. Geochemical surveys based on the chemical analysis of samples of active stream sediment from drainage courses have long been used as an exploration tool worldwide.

The underlying premise is that stream sediments are composite products of erosion and weathering and thus represent the source catchment area of the stream drainage network.

ABSTRACT Worldwide use of stream sediment geochemistry for almost 50 years has shown it to be a robust method for identifying areas of high mineral potential.

The basic premise is that a stream sediment is representative of the products of weathering and erosion upstream of the sample site. However, detailed studies show that this premise greatly oversimplifies the real situation.1/5(1).

Geochemical zonality is one of the most outstanding features of the primary geochemical haloes of non-metallic deposits in general and hydrothermal and meta-morphic ones in particular.

The oxial geochemical zonality of the primary haloes of deposits is universal, that is to say there is an ordered distribution of element haloes up the dip of.
