The text presented here is intended to provide a broad and diverse view of the current stages of geological prospecting of sedimentary deposits in their preliminary phase based on indirect exploration methods.geological prospecting of sedimentary deposits in their preliminary phase based on indirect exploration methods.The different topics have been developed on the basis of the fundamentals of the above-mentioned sciences.In fact, the text is presented in two parts; the first part consists of the preliminary geological mining exploration, by means of indirect exploration methods, in addition to its basic instrumental analysis, and consists of four chapters:The first deals with the study of general principles, economic importance, distribution, distinctive features, stratigraphic, tectonic, and regional geology.The second consists of the interpretation of different types of charts; topographic, geological, geophysical, geochemical, as well as geochemical aspects and the preliminary integration of the information.The third chapter deals with the beginning of the field work and sampling.sampling.
