现象在安徽A119测线上,采用十二次覆盖观测,所得的常规水平叠加剖面于236—260叠加段出现了严重的条带状异常(图1)。在此异常带内有时仍然看到一些有效信息的痕迹,但是相邻地段的可连续追踪的强反射波在此出现中断,或者消失,这势必给地震资料的解释带来困难。 Phenomenon In Anhui A119 survey line, using twelve coverage observations, the resulting conventional horizontal superimposed section in 236-260 overlay segment appeared serious strip abnormalities (Figure 1). Some traces of valid information are still sometimes seen in this anomalous zone, however, the continuously tracable strong reflected waves in adjacent areas are interrupted or disappeared, which will inevitably make the interpretation of seismic data difficult.
