火山熔岩溢流到下伏地层之上,使地层表层经受高温过程形成烘烤层。当该烘烤作用是本岩层的最后一次热事件时,方符合热释光技术测年龄的采样要求。本样品采自山西省大同县阁老山公社黑山南狼窝沟和阳高县下深井公社东水头村水库西岸两处,烘烤沉积物为第四纪黄土。测龄前首先对烘烤和非烘烤沉积物的物质成分、微结构和表面形态进行了分析鉴定,
Volcanic lava overflows into the underlying formation, allowing the formation to undergo a high temperature process to form a toasted layer. When the bake is the last thermal event of the rock formation, it meets the sampling requirements of thermoluminescence technique. The samples were collected from two sites, namely, Woluo Gully, South Shannuo, Datong County, Shanxi Province and Wushuogou East Shishuitou Reservoir, Yanggao County. The bake deposits were Quaternary loess. Before the age of the test, the material composition, the microstructure and the surface morphology of the baked and non-baked sediments were firstly analyzed and identified.
