    Description

    Basic questions concerning Australia's soil and regolith resources are addressed through measurement of nuclides produced by cosmic rays in near-surface minerals. Cosmogenic Be-10, Ne-21 and Al-26 are used to (i) quantify the sustainable levels of soil loss, (ii) assess long-term mixing rates, (iii) quantify dispersion and flux of regolith materials from hill-slopes to rivers, and (iv) determine the rates of sediment movement through Australian rivers and floodplains, including sediment-adsorbed pollutants. The research has strong implications for the usage and conservation of soil, sediments and weathered deposits for agriculture, mineral resources, and sedimentary waste disposal.
