Abstract
Abstract. For work materials used multispectral satellite imagery Landsat (7 channels), medium spatial resolution (14,25–90 m) and a digital elevation model (data SRTM). For interpretation of satellite images and especially their infrared and thermal channels allocated buried paleovalleys pre-paleogene age. Their total length is 228 km. By manifestation of the content of remote sensing paleovalleys distinctly divided into two types, long ribbon-like read in materials and space survey highlights a network of small lakes. By the nature of the relationship established that the second type of river paleovalleys flogs first. On this basis, proposed to allocate two uneven river paleosystem. The most ancient paleovalleys first type can presumably be attributed to karst erosion, blurry chalk and carbon deposits foundation. Paleovalleys may include significant groundwater resources as drinking and industrial purposes. Also we can control the position paleovalleys zinc and bauxite mineralization area and alluvial deposits include uranium mineralization valleys infiltration type and placer gold. Direction paleovalleys choppy, but in general they have a north-east orientation, which is controlled by tectonic zones of the foundation. These zones are defined as the burial place themselves paleovalleys and position of karst cavities in areas interfacing with other structures orientation. The association of mineralization to the caverns in the beds paleovalleys could generally present conditions of formation of mineralization and carry it to the "Niagara" type. The term is obviously best reflects the mechanism of formation of these ores.

The term is obviously best reflects the mechanism of formation of these ores (Figure 4). But in general they have a northeast orientation, which is controlled by tectonic zones of the foundation
Mineralization is controlled by the position of one side development of paleovalleys, and on the other side are the tectonic zones of the foundation.These zones were determined place of burial paleovalleys and the position of karst cavities in areas conjugation of divergent structures
Summary
For work we used materials of multispectral satellite imagery Landsat (7 channels) medium spatial resolution (14,25-90 m) and a digital elevation model (data SRTM). Initial data for the performance of work were: - Archival materials of multispectral satellite imagery Landsat. Spectral ranges channels are: PAN - 520-900 nm, 1 - 450 - 515 nm, 2 - 525-605 nm, 3 630-690 nm, 4 - 750 -900 nm, 5 - 1550-1750 nm, 6 - 1040012500 nm, 7 - 2090-2350 nm. The spatial resolution of images is 14.25 m for PAN channel, 30 m for 1, 2, 3, 4, 5 and 7 channels and 60 m for 6 channels (Figure 1). Landsat archive materials are taken on the site of Marilend State University (USA): http://glcfapp.glcf.umd.edu:8080/esdi/index.jsp; - A digital elevation model (spatial resolution 90 m) is taken on the site of the University of Maryland (USA): http://glcfapp.glcf.umd.edu:8080/esdi/index.jsp
