Continuous reflection work over about 47 miles of total traverses was carried out south of Loxton. The individual lines are not interconnected and the correlation method is used for tie in. Shothole interval is 1/4 mile with straddle spread 1320 feet each side of shothole. The report contains a very generalised discussion +of the geology of the area and an extremely short and inadequate +chapter on the interpretation of the results. One reflector in the +vicinity of 0.600 seconds was carried through, but the event is not iidentified as to its significance within the stratigraphic column. The attached contour plan again shows an unidentified event of 0.400 to 0.570 (?) double time. The only information of any significance of+ this report is the delineation of structures with a marked and regular NW trend, observed over the whole area investigated. However, the value of this information is greatly reduced the fact, that no indication is given in what geological unit these structures are developed.
