The solution of geological problems in ore districts by seismic methods is reduced to the identification of inhomogeneities of the velocity section, with which certain geological objects are associated.
The results of seismic surveys in areas composed of magmatic formations indicate a large role in the formation of wave fields of elements of discontinuous tectonics.
The task of compiling velocity models of ore districts is extremely difficult due to the variety of forms of distribution of elastic parameters in magmatic rocks and an insufficiently developed set of methods of their study ...
Based on detailed studies of elastic parameters of well cores in the Kafan ore field it is shown that the velocity section of magmatic rocks is represented mainly by layers of small thickness (up to 100 m), among which thin layers with a thickness of 10-20 m predominate ...
The need to investigate deep horizons, which are associated with the prospects of discovering oil and gas fields in Northern Afghanistan, requires the use of effective methods of interpretation of complex wave fields ...
Despite the large volume of seismic exploration in ore areas is still poorly covered the question of the properties of seismic boundaries in igneous rocks. The information about them is based mainly on the results of interpretation of kinematic characteristics of wave fields, which give an opportunity to get a fairly complete idea about the morphology of boundaries, but very little - about their detailed velocity structure ...
The Kafan mining district, within the limits of which exploration and exploitation of copper-molybdenum ore deposits are carried out, is most fully explored by prospecting and exploration works to the depth of 300-400 meters. The problem of increasing ore reserves in this area is closely connected with the need to increase the depth of exploration. In this connection, in 1971 the complex of geological and geophysical studies included seismic methods of exploration, the main task of which was to obtain data on the depth structure of structures controlling copper-molybdenum mineralization. ...
