On analysis and geological interpretation for the records of continuous seismic prospecting.

Abstract

Sonic survey is one of the most useful means for marine geological surveying. When surveying courses are properly arranged and some knowledges on bottom rock are prepared by any method else, it is possible to compose an under-sea geological map as well as continuous profiles by analysing sonic records. In this paper, the present writer describes his analysing method and interpreting procedures which have been used in the case of Tsugaru and Akashi Straits, with some illustrations of reflective pattern as characteristic features corresponding to lithological conditions.
