| Sampling points are placed uniformly as possible in the river valleys, and only in areas favorable for the localization of body minerals, testing thickens. Thus, sites are being tested in more detail the development of magmatic complexes that are favorable for the localization of mineralization folded and discontinuous structural-tectonic elements, contact zone of intrusive massifs of the field distribution of hydrothermally altered rocks and vein quartz. Regional schlich searches in potentially ore districts are combined with other types of exploration. Most often simultaneously with schlich testing of spaces within the watershed holds litho-geochemical diluvial-eluvial deposits or bedrock outcrops in the. In the latter case, the selected samples to establish the primary sources of minerals encountered in schlich anomalies. In addition, segments of river valleys, have low activity, erosion and stagnant waters, instead of using schlich litho-geochemical samples of bottom silt-clay sediments. From surface watercourses and natural way to the surface of groundwater hydrochemical selected sample. Search works well also based on data from various regional geophysical studies in their ground and air versions. Comparison of various factual material with the results schlich search allows you to assess the overall prospects for ore in the region as a whole and to identify specific sites for more detailed research. Stage 2 - geological survey of the 1:50 000 scale with a common quest. With a very complex geological structure of the studied areas of this stage can be executed, as an exception, the scale of 1:25000. Named searches are conducted within a prospective area identified as a result of its first stage. They represent the core of the planned large-scale study of the geological structure of the territories and the allocation of local areas and structures that are promising for the detection of mineral deposits. |
