• W2050320960 abstract "The geochemistry of clastic sediments is controlled by at least four factors: source rock composition, weathering of the source rocks, sorting of the weathered detritus and post-depositional alteration during diagenesis and metamorphism. In order to evaluate the relative importance of these factors major, trace and rare-earth element contents were determined for distal and proximal clastic turbidites from the Archaean Quetico Metasedimentary Belt. The degree of metamorphism of the samples ranges from middle greenschist to upper amphibolite facies. Simple mixing of Archaean mafic and acidic rocks of similar composition to those found in the adjacent granite—greenstone terrains will account for the TiO2, FeOT, MgO, Cr, Sc, Y and HREE contents of the clastic turbidites. The metasediments are enriched in LREE relative to the mafic—acidic rock mixing line, indicating that the acidic source was enriched in the LREE compared to Archaean terrains from other parts of the world. Some Quetico turbidites have an additional Fe-rich source component, possibly a chemical sediment incorporated at the time of turbidite slumping. CaO, Na2O, K2O, Rb and Sr form trends on bivariant plots that are oblique to the mafic—acidic rock mixing line, and hence cannot be accounted for by simple mixing of the source rocks. Chemical weathering of feldspars prior to deposition can account for CaO, Na2O, K2O, Rb and Sr trends, since CaO, Na2O and Sr are lost to the weathering solutions and K2O and Rb are retained on the product clays. The higher Na2OCaO, K2ONa2O, RbK2O and Sr/CaO ratios, but lower CaO content, of the distal samples suggest that they were derived from a bulk sediment that had experienced a greater degree of chemical weathering than the proximal sediments. Sorting is the factor that most strongly influences the composition of individual samples. Within the proximal sample group the coarse-grained metagraywackes, with their higher quartz, feldspar and heavy-mineral contents, are enriched in SiO2, CaO, Na2O, Sr, LREE, Zr and Hf relative to the fine-grained clay-rich metapelites. Metapelites are enriched in TiO2, Al2O3, FeOT, MgO, K2O, Cr, Zn, Sc, Y, HREE, Cs and Rb as a result of their higher clay contents. Thus, the use of clastic sediment compositions in determining average crustal compositions (e.g. for the REE) can only give satisfactory results when all grain-size fractions are sampled in their correct relative proportions. The chemical differences observed between the high- and low-grade samples can be accounted for by source rock type, chemical weathering of the source rocks or sorting; post-depositional element mobility does not appear to be an important factor in determining the composition of the Quetico metasediments." @default.
