摘要: Thermoluminescence (TL) and infra-red stimulated luminescence (IRSL) ages have been determined for loess from the Columbia Plateau region of southeast Washington northeast Oregon, U.S.A. The IRSL ED values appear to be tending towards a maximum level lower than that TL ages. In general, are in stratigraphic order agree well with age control, form 14C dated tephra units derived various eruptions Mount St Helens.
