| 摘 要： | 用作者研制的RS 81 1型热释光仪对云南昭通鱼洞水库地区两条断层的破碎带内发育的方解石脉进行了热释光年代测定和显微构造分析 .结果显示 :2条断层破碎带内发育 4期方解石脉 ,其中有 3期发生了变形 .F1 断层距今 5× 1 0 4 a以来 ,F2 断层距今 2 5× 1 0 4 a以来没有强烈活动的迹象 .断层泥中石英颗粒表面形态分析结果与热释光法相同 .

| Abstract: | By using the author's self-made RS-81-1 TL dating device,the TL dating and microscopic structure analysis on calcite veins in 2 fault shatter belts in Yudong reservoir,Yunnan Prov.,China,are done.The result shows that there are 4 groups of calcite veins which form in different time,among them 3 groups have been deformed.F1 fault since 15×104 years and F2 fault since 25×104 years have no evidence of activity.The surface characteristic analysis on quartz coarse-grain indicates the same result with TL dating method. |
