Abstract

Purpose. Exploration and predicting the prospective areas in the Zhezkazgan ore region to set up detailed prospecting and evaluation works using new integrated technologies of prediction constructions in the mineral deposits geology. Methods. An integrated methodological approach is used, including methods for deciphering the Earth’s remote sensing (ERS) data, the use of geophysical data and methods of analogy and actualism. All constructions are made in accordance with the principles of shock-explosive tectonics (SET). Prediction constructions are started with the selection of remote sensing data for the studied region and interpretation based on the processing of radar satellite images obtained from the Radarsat-1 satellite. The radar satellite images are processed in the Erdas Imagine software package. Findings. New local prospective areas have been identified, within which it is expected to discover the deposits. Their reserves are to replenish the depleted ore base in the Zhezkazgan region. Area of the gravity maximum 1 (the Near), considered to be the most promising, is located in close proximity to the city of Zhezkazgan; area of the gravity maximum 2 (the Middle); area of the gravity maximum 3 (the Distant-Tabylga); area of the gravity maximum 6 (the Central). A prospective area has been also revealed, overlaid by a loose sediment cover and located inside the Terekty ring structure, as well as the area of a thick stratum of pyritized grey sandstones, which is adjacent to the Sh-2 well drilled to the south of the Zhezkazgan field. Originality. The use of a new prediction technology, in contrast to the known ones, is conditioned by the widespread use of the latest remote information from satellite images, which increases the accuracy of identifying the prospective areas of fields. Practical implications. The new technology for predicting mineral deposits makes it possible to significantly reduce the areas exposed to priority prospecting, which provides significant cost savings.

Highlights

The scientific significance of the new prediction techno-It is well known that in the last 2-3 decades in Kazakhstan, which is considered a country rich in mineral resources, there is an acute problem of singleindustry cities (Zhezkazgan, Balkhash, etc.) that appeared on the basis of large deposits discovered in the last century
As a specific example, the detailed prediction construction in the Zhezkazgan region is proposed in two options: 1. On the basis of ring structures, manifested in relief, taking into account their relatively young age
On the basis of ring structures depicted in satellite images, but not manifested in the relief, that indicates their older age, combined with one of the structures manifested in the relief, but the morphological elements of which clearly contain and control all deposits of the Zhezkazgan ore region

Summary

Introduction

The scientific significance of the new prediction techno-It is well known that in the last 2-3 decades in Kazakhstan, which is considered a country rich in mineral resources, there is an acute problem of singleindustry cities (Zhezkazgan, Balkhash, etc.) that appeared on the basis of large deposits discovered in the last century. For the accelerated replenishment of the mineral resource deposits base in these cities, it is necessary to set up prospecting operations using new technologies. In this regard, the authors propose a new technology for regional and local mineral deposits prediction, based on the principles of shock-explosive tectonics (SET), geophysical data and Earth’s remote sensing (ERS) data in the Zhezkazgan ore region. The new technology, based on the use of space information, unknown before the onset of the space age, allows, using simple techniques, to identify these patterns and rely on them in modern prediction constructions. The scientific significance of the proposed technology is covered in numerous publications [5]-[8] and has been patented [9]
