摘要: 从天山北麓采集了晚第四纪风成、冰水相和河流相的粉砂样品,对它们进行了热释光、绿光释光和红外释光的古剂量测定。结果表明,对于经充分光晒退的风积物样品,三者的测量结果没有差别,而对于曝光不足的冰水相样品,热释光获得的古剂量值明显大于绿光释光和红外释光的古剂量值

Abstract: Seven samples of wind blow,glaciofluvial and fluvial sediments are collected from northern Tianshan Mountain Each sample is dated for fine grain using the the luminescence techinque to get three paleodose of TL,GLSL and IRSL Comparison of the paleodoses shows that they are in agreement for win blow samples,but different for the the samples that were not totally bleached before sedimented The paleodose of TL is larger than those of GLSl,IRSL
