Abstract Petrographic, geochemical, and isotopic data for turbidites from a variety of tectonic settings exhibit considerable variability that is related to tectonic association. Passive margin turbidites (Trailing Edge, Continental Collision) display high framework quartz (Q) content in sands, evolved major element compositions (high Si Al , K Na ), incompatible element enrichments (high Th Sc , La Sc , La Yb ), negative Eu-anomalies and variable Th U ratios. They have low 143 Nd 144 Nd and… Expand
