Abstract

Optically Stimulated Luminescence (OSL) dating of quartz sand grains is used to date young deposits across disciplines in geology and archaeology. OSL dating requires that the quartz mineral is sensitized, or pre-conditioned to produce a luminescence signal following exposure to ionizing radiation. The geological processes that enhance the OSL sensitivity (photons released per given radiation dose and sediment mass) remain uncertain. Our Research Objectives are to investigate the geomorphic controls (bedrock source, fluvial transport, and hillslope processes) on OSL sensitivity using sediment collected along the Pagliara River in NE Sicily.

The Pagliara catchment (13km2) is tectonically active and drains metamorphic bedrock. Drainages are primarily E or W facing, or a combination of both. Except T4, which is primarily S facing.
