Abstract
Heavy minerals provide key constraints on sediment provenance by describing the composition of a source terrain, documenting changes in source or deeper levels of exhumation. Fission-track analysis of detrital apatite and zircon provides complementary information on timing and rates of source exhumation that helps place heavy mineral evidence within a temporal framework. While combined heavy mineral—fission-track analyses strengthen provenance studies, the effects of lithological bias, small datasets and non-uniqueness of fission-track ages (and thermochronometric ages in general) can limit or hinder interpretation. Using examples these issues are discussed and new approaches are presented that link high precision geochemical data from single detrital grains with sediment composition and detrital age structure. Combined geochemical and isotopic signatures extracted from single grains permit more detailed resolution of source composition and evolution that strengthen the role of heavy mineral studies and fission-track thermochronometry.
