Geochemical constraints on the composition of sandstone matrix and the interpretation of Detrital modes

Abstract

Using petrographic detrital modes and major-element concentrations in matrix-rich sandstones, it is possible to calculate upper limits of the amounts of various detrital components that may have recrystallized in sandstone matrices. With exception of samples in which the matrix includes large contributions of recrystallized detrital feldspar, detrital modes of graywackes can provide accurate provenance and tectonic setting information.
