STATISTICAL EVALUATION OF DEEP CRUSTAL REFLECTIONS IN GERMANY

Abstract
By a routine method of observation during exploration reflection measurements, sufficient data were compiled to allow significant statistical conclusions concerning deep crustal reflectors. The appearance of deep crustal reflections differs considerably from that of reflections from shallow sedimentary beds. They correlate only over short distances, seldom more than a few kilometers. The reflection times display quite a scatter, even over small areas. In many cases the reflected signal is typically broadened to continue over a few cycles. Following this reflection band along a profile, the main energy is frequently shifting from one phase to another until finally it disappears completely. A new method of wide angle reflection observations using a common reflection point technique was used to support and confirm results of the statistical analysis.
