采集湖光岩玛尔湖周围部分岩洞内的岩样及岩壁下和湖岸边的砂土样品,用粗颗粒法测量它们的热释光和光释光;用复合作用剂量响应模型分析热释光和光释光剂量响应,并计算对应的热释光和光释光古剂量.结果表明:相同采样点的样品,热释光和光释光古剂量间都存在一些差异:不同采样点样品的释光剂量相差很大;热释光古剂量测量值较准确的样品,光释光古剂量测量值与热释光测量值无显著的数量级差别.此测量分析对第四纪火山考古有一定参考意义.
採集湖光巖瑪爾湖週圍部分巖洞內的巖樣及巖壁下和湖岸邊的砂土樣品,用粗顆粒法測量它們的熱釋光和光釋光;用複閤作用劑量響應模型分析熱釋光和光釋光劑量響應,併計算對應的熱釋光和光釋光古劑量.結果錶明:相同採樣點的樣品,熱釋光和光釋光古劑量間都存在一些差異:不同採樣點樣品的釋光劑量相差很大;熱釋光古劑量測量值較準確的樣品,光釋光古劑量測量值與熱釋光測量值無顯著的數量級差彆.此測量分析對第四紀火山攷古有一定參攷意義.

Sand samples were collected at different locations from the Huguangyan Maar Lake region in Zhanjiang, Guangdong province in south China.Thermoluminescence (TL) and optical stimulated luminescence (OSL) were measured with coarse grain technique.The TL and OSL dose response were analyzed and their ancient doses were calculated.The result shows that ancient doses measured with TL technique differ from those measured with OSL technique for the same sample,whereas for the samples whose TL ancient dose is close to the veraciousness,there were no evident degree of difference between the ancient doses by OSL and TL.The experiments and analyses can be used for reference in Quaternary period volcano dating.
