Geodynamical model of oil-gas and mineral deposits using RS&GIS Western Uzbekistan
Abstract
This paper deals with the application of complex study of Remote Sensing images and deep Lithospheric structures to the knowledge of spatial interrelation between regional lineaments and oil-gas and mineral deposits in Uzbekistan. Deciphering of structural units of Uzbekistan territory using space ASTER images allows us to reveal regional, deeprooted lineament, extending in latitudinal direction over Uzbekistan territory and neighboring countries. Thus lineament could penetrate the Earth up to deep Lithosphere layers, inheriting a position of old fault-lineament systems which origin related to Paleocene tectonic processes. The most extended latitudinal lineament is the "Transregional lineament of Central Asia" located within 42-44N zone. It stretches for more than 2000km from Sultan-Uvais mountains (Karakalpakstan), through Kyzylkums and Nurata mountains (Uzbekistan), Turkestan-Alay and Atbashi-Inychek mountains (Kyrgyzstan), to Chinese border with possible extension along the Chinese Tien-Shan. The main objective is to associate the surface «indicators» as geological, geophysical and tectonic base of data using RS&GIS with the purpose toidentify the occurrence special geoobjects of economic interest. Additionally, it will be possible to evaluate geospatial distributions of these altered zones related to morphological structures using Digital Elevation Modelling/DEM/ products of ASTER images. RS&GIS methods were used to determine the interrelations of the volcanic and granitic rocks distribution-mineralization-alteration with the faults-lineaments, circular structures. The alteration zones, the tectonic lines and the Circular structures related to the cones and calderas determined these methods and checked by group truth studies may be target areas to explore for some new oil-gas and ore deposits. As a result, our investigations envelops more then 10 deposits in Western Uzbekistan.In conclusion, it is necessary to note that such structures are well-known in the American, Australian continents. They are recognizes as deep structures and served as channels fo the heat (endogenous) energy, magmas and fluids to come out of the core and mantle of the Earth. It gives us an opportunity to concentrate there our efforts for prospecting of such kind oil-gas and mineral deposits.
