Abstract
THE geochemical distribution of elements in sedimentary rocks is genetically complex because they may be concentrated in the detrital fraction or resistates; the clay fraction; the chemically precipitated fraction; and the organically precipitated fraction. It follows that advances in sedimentary geochemistry depend on increased knowledge of the distribution of elements in these four constituents. Hence, analysis of the bulk rock, which is generally the standard practice in igneous geochemistry, may not be a successful method when applied to problems in sedimentary geochemistry.
