Quaternary sediments can be investigated by different physical, geophysical, and geochemical methods and modern remote-sensing techniques. The interpretation of remote-sensing imagery plays an efficient role in the study of geological objects and various geological processes. It is conditioned by the various technogenic factors and ea the composition and sequence of deposits of the area. The additional information from satellite images makes it possible to identify types of sediments. Combining satellite data with geological, geophysical, and geochemical approaches allows to analyze various types of anthropogenic deposits and to determine their main characteristics. It is proposed to apply remote sensing methods and the thermoluminescence method to anthropogenic sediments and determine their age. Thermoluminescence is applied to solve various geochronological tasks and to dateq Quaternary deposits. The main concepts of the thermoluminescence method have been considered. Our proposed approach for the dating of anthropogenic deposits is based on the Smakula-Dexter formula. The Smakula-Dexter formula calculates the concentration of radiation centers. A relation has been established between the age of the sample and the concentration of radiation centers. By solving a differential equation, a mathematical formula has been derived for the radiation coefficient, which is a component of the Smakula-Dexter formula. The higher the concentration of radiation centern, the older the sample is. Remote sensing methods and thermoluminescence can be combined to determine the age of rocks.
