Abstract:
Clear-cut reflection records are obtained only with sharply defined, conformable bedding, of considerable lateral extent, uncomplicated by steep folding or faulting. Deviations from these conditions will give rise to waves returning from the earth from a number of directions at approximately the same time. Such multi-directional arrivals produce unsatisfactory reflection records on the usual visual seismograph record. A method is presented for overcoming these difficulties by analyzing the received vibrations and separating them into their component wave trains.
