摘　　要：ＴＬ年代方法弥补了１４Ｃ、Ｋ－Ａｒ等测年方法的不足，是第四纪地质学中一种新的重要测年手段．采用粗颗粒技术对湛江湖光岩的火山岩作ＴＬ年龄测定的结果表明，该地在晚更新世曾发生过不止一次火山喷发，其最近一次喷发的年代为９３ｋａ前．TL dating method is a new and important technique in Quaternary geology, and it makes up deficiency of 14 C, K Ar method,and so on.The quartz inclusion technique was used for TL age determination to volcanic rocks from Huguangyan,Zhanjiang.The results demonstrate that the volcano erupted more than one time in this place, and the nearest volcanic eruption based on TL datum is 93 ka ago.
