在荷兰三角洲的潮滩上进行了一次地震勘测,使用的是30kg的重锤震源、12道增强地震仪,每道采用固有频率为100Hz的单个检波器．总长为2600m、六次CDP覆盖、探测深度为10-400m的几条地震测线,是由Utrecht大学的学生在1981和1982年夏天实习期间完成的．这个缺失了风化层、由水饱和的沙子组成的潮滩,为高分辨率的地震勘探提供了有利的条件．震源所产生的纵波有一个大约200Hz的峰值频率,因此达到3-5m的垂直分辨率．其水平分辨率也达到3-5m,用这样高质量的资料足以进行地震地层学的解释． 从地震测线附近的一些浅井得到的沉积序列与地震剖面图上半部分的震相有关．而其下半部分的震相可用区域地质得到的地质岩层来进行识别．一些不整合现象提供了有关区域性海侵和海退周期的证据．
A seismic survey was conducted on a tidal flat in the Dutch Triangle, using a 30 kg heavy hammer source and 12 enhanced seismometers, each using a single detector with a natural frequency of 100 Hz. A total of 2600 m long, six CDP coverage and several seismic surveys with a probing depth of 10-400 m were completed by Utrecht University students during their internship in 1981 and 1982. This tidal flat, which is depleted in weathered layers and is saturated with water, provides favorable conditions for high-resolution seismic exploration. The longitudinal wave generated by the source has a peak frequency of about 200 Hz, thus achieving a vertical resolution of 3-5 m. Its horizontal resolution also reaches 3-5m, with such high-quality data sufficient for seismic stratigraphic interpretation. The sedimentary sequence obtained from some shallow wells near the seismic line is related to the seismic facies in the upper part of the seismic profile. The seismic facies in the lower part of the earth can be identified by geological formations obtained from the geology of the area. Some of the unconformities provide evidence of regional transgressions and regression cycles.
