Application of processing and transformation of aeromagnetic data in searching for hidden gold-bearing mineralization of the Sardarya basin

Abstract. This article proposes solutions for identifying forecast zones in closed areas between South Tamdytau and North Aristantau based on processing and transformation of aeromagnetic survey data using the Standard Deviation (SD), Phase Symmetry (PS), and Amplitude Thresholding (AT) methods. As a result, the use of modern Amplitude Thresholding processing methods made it possible to identify ore-controlling structures, such as the southern fault of the Muruntau ore field and its continuation with a bend in the closed areas of the Sardarya Basin. To process aeromagnetic data for the purpose of forecasting and searching for hidden gold mineralization, the author’s technological scheme has been developed, reflecting the sequence of stages of processing, filtration and transformation. It has been established that the identified anomalies obtained by the method of processing phase symmetry according to aeromagnetic survey data on a scale of 1:50 000, in terms of strike parameters and sizes correspond to the zones of distribution of gold halos.Key words: deposit, gold, fault, magnetic susceptibility, amplitude filtration, symmetry phase, standard deviation.
