However, it is well known that results of such surveys are often extremely erratic and dificult to reproduce or confirm. Such problems are typical of geochemical patterns for elements that are principally transported in stream sediments as the constituents of rare grains of havy minerals( Fletcher and Day, 1988a, b ) ER -
