Stream Sediment Geochemistry in Today ’ s Exploration World

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 situation07/11/2017· The commonly practiced collection of stream sediment samples in mineral exploration, including the Canadian British Columbia (BC) government’s Regional Geochemical Surveys (RGS), is the ‘grab’ method of collecting fine fluvial silt by hand which, in the typical < 80mesh fraction usually analyzed, almost always includes some organic phase material alongTHE GEOCHEMICAL LITHIC DRAINAGE SEDIMENT (LDS) SAMPLING METHOD
