Application of Remote Sensing Data for Preliminary Exploration by Determining the Spectral Reflectivity of Outcrops and Soils at the Tochka Deposit (EKR)

Abstract

Using the example of remote methods of Earth exploration and the use of satellite images obtained by the Sentinel-2 satellite apparatus, the possibility of conducting primary geological exploration to identify geological anomalies (objects) and drawing up a more accurate plan for fieldwork is considered. The geological and geochemical characteristics of the studied area are presented. Interpretation and analysis of the data obtained using multispectral remote sensing of the earth has been carried out. An innovative methodology capable of detecting spectral signatures of lithium-containing pegmatites is presented, as well as well-known remote sensing algorithms for detecting halos of changes associated with these pegmatite bodies. The method of identifying the main spectral wavelengths of reflection and absorption of some minerals is described. It is shown that with the use of this technique, the time of geological exploration is significantly reduced and the financial costs of conducting geological exploration and depreciation of the technical means used are significantly reduced. And also, it is planned to improve this methodology
