摘要：

The behaviour of ESR signals due to titanium and aluminium centres in quartz sand on exposure to sunlight has been investigated. Samples of sand were recovered from cores taken off the coast of southeast Australia, at Forster-Tuncurry, and at an inland lake, Lake George. Naturally irradiated samples, and also samples which were annealed and then artificially irradiated with gamma rays, were used. The ESR signal due to titanium centres shows promise for dating the last exposure to sunlight of quartz grains.
