| Regional studies are divided on the scope of work into two groups: geological and geophysical studies of the scale of 1:1000 000 - 1:500 000 and geophysical, geological surveying, hydrogeological and geotechnical work scale 1:200000 (1:100000). Schlich search was escorted into the main study of the second subgroup (scale 1:200 000 and 1:100 000). They run a complex with a boulder, geochemical, geomorphological, geophysical ground and remote methods of research and interpretation of the search space are accompanied by photographs. As a result of regional works are distinguished promising geological structures within which may be identified by indigenous shallow deposits and deposits, set the search criteria and indications, estimated probable reserves of P3 category and determined the direction of further geological survey and prospecting. The end result is the state geological map, accompanied by maps of minerals and prediction of mineral resources. Schlich search of work possible to detect in the valleys of major streams mechanical dispersion halos, which characterize the weathering of deposits that lie under a thin cover of unconsolidated sediments. On the basis of complex structural-geological, geomorphological research provides opportunities for addressing the linkage identified schlich halos with indigenous sources of ore mineralization, or with sites of possible formation of placers. Schlich testing on a scale 1:200000 - 1:100000 carried by a shuttle to the regions with strongly dissected relief and area - in the plain areas. While being tested main streams of high order, average orders of drainage system, as well as the mouth of small tributaries. Schlich testing are basically the modern river bed facies, at least - the old alluvium terraces. Density selection schlich samples determined by the features a particular area searches, structural details of topography and properties schlich minerals. |
