Abstract:

The report is a project to investigate variations in continental crustal structure by seismic methods, using artificial sources such as quarry blasts at ranges of 100 to 200 kilometres. The project involves the construction of a transportable array of detectors with linear dimensions of several kilometres. The equipments may be divided into four main units. Firstly, there is the short point unit, which records on magnetic tape a time signal radio station, a crystal clock output, the shot instant and a strong motion geophone channel. Secondly, there is the transportable array with digital magnetic tape recording of ten information channels and of timing and control information. At the time of recording the digital information on any one channel may be replayed to a simple one channel digital-to-analogue converter, designed to drive a galvanometer recorder. Author
