【摘要】 <正> Ⅰ. INTRODUCTION In the method of ESR dating of quartz grains in loess, the determination of the previously acquired geological dose is an important step. It has been supposed that by exposure to sunlight the ESR signal intensity of E′ center in quartz grains could be erased to zero or a limit value when the loess was transported by wind from desert to the deposition site, be-更多还原
