Abstract
Results of a feasibility study on luminescence dating of neotectonic e vents as recorded in fault gouges and buried soils formed on landslide debris are reported. It is suggested that clay mineralogical data on illite and chlorite can provide a reasonable estimate on the thermal e xcursion (and hence on resetting of the luminescence clock) during fau lting. The thermoluminescence ages are consistent with the available r adiocarbon ages and have been used to infer that Naini Lake was formed at ca. 40-50 ka.
