Title
SEISMIC RESOLUTION DEPENDENCE OF IDENTIFYING ANCIENT VOLCANOS

摘要
地震资料有限的垂向分辨率造成地下某些古火山的几何外形与其地震反射图象大相径庭;而地震勘探现有的水平分辨率又远远不能将古火山的内部结构在地震剖面中显示出来.本文着重分析了地震垂向分辨率和水平分辨率对古火山解释结果的影响,以实例说明地震分辨率在古火山地震识别中的重要意义.
Abstract
The limited vertical seismic resolution leads to the great discrepancy of the geometry of some ancient volcanos from their corresponding seismograms while the available horizontal seismic resolution stops us from understanding the volcanos internal structure. This paper will centre attention on the analysis related to the significant roles that the seismic resolution plays in interpreting ancient volcanos.
