Structural characteristics of Yanyuan basin deduced from geophysical data and it dynamic implication

  • 摘要: 本文基于覆盖盐源盆地的短周期天然地震台阵和所布设的一条人工地震测线所获得的人工地震数据,从中提取地震能量属性,并利用地震层析反演法获得该地区浅部地震速度结构,继而对短周期地震台阵一个月的噪声数据进行互相关方法获得经验格林函数,通过时频分析获得相速度频散曲线,并且反演获得不同深度S波速度分布。研究结果表明盐源盆地地震反射特征主要分为三层:浅部速度低,速度范围为1—2.1 km/s,具有连续性好、强反射轴,反射能量强的特征,为新生代沉积地层,新生代盆地整体呈南深北浅,沉积发育和构造形态受盐源断裂控制;中部速度为中低速,速度范围为3.5—4.5 km/s,反射轴不连续、反射能量较弱,为三叠系地层;深部速度高,地震反射较为杂乱,反射能量弱,为古生代地层;上地壳存在滑脱面,该界面为沉积盖层与结晶基底的分界面,且向浅部发育一系列断层,金河—箐河断裂为盐源盆地与康滇地块的分界断裂,这些断裂带也是盐源盆地地震频发的部位。
