When particulate sediment accumulates in a sedimentary environment it is referred to as DETRITAL sediment. A rock formed when this lithifies is a DETRITAL SEDIMENTARY ROCK. Such rocks are further classified based on their grain sizes, shapes, arrangements, and (in some cases) mineralogy.

DETRITAL THERMOCHRONOLOGY; Detrital thermochronology involves dating of single grains of clastic sediment, in particular apatite, zircon, and white mica. Different isotopic dating techniques are available to date such minerals, including (U-Th)/He, fission-track analysis, Ar/Ar, or U-Pb dating.
