Geophysical Research at Different Stages of Development of Deposits of Copper Sandstones in Kazakhstan

Using the example of the Zhaman-Aybat deposit, the possibilities of geophysical methods at the stages of forecasting and solving prospecting and exploration geological problems of deposits of copper sandstones in Kazakhstan are shown. The position and dimensions of the Zhaman-Aybat structure and the depth of productive deposits are reliably determined by seismic exploration. According to the local positive anomalies of the gravitational field, separate blocks of rocks were identified, and according to the data of vertical dipole sounding, the depth of the high-resistance horizon identified with the roof of the rocks of the Zhezkazgan formation was determined. By probing the formation of the field in the depth range of 500- 800 m, local anomalies associated with productive deposits of the Taskuduk formation were traced. Geophysical studies of wells and the results of testing have increased the reliability of determining the parameters necessary for recalculation of copper ore reserves. Deep drilling has confirmed the high accuracy of geophysical work.
