El' A. Geology, composition and forming conditions of gold deposits in the Middle-Dnieprean region (Ukrainian Shield)

Important questions of the geology and forming conditions for the typical gold deposits in the Middle-Dnieprean granite-greenstone terrain have been established. Methods: formational, petrographical, chemical, mineralogical, mineragraphical, microzondic analyses. It has been performed their typization as well as regional geology and tectonics considered as a whole, and ore zones composition and morphology, ore bodies shape and size, country-rock complex and wall-rock metasomatic alteration patterns presented. Detailed ore mineralogy studies are accompanied by their distribution and relationship investigations, mineral associations have been established and a simple model has been designed for their timing. Ore-forming conditions have been reconstructed and search-prospecting criteria proposed for gold mineralization. Ontained results could be used for gold search-prospecting works in the Middle-Dnieprean granite-greenstone terrain.
