Among the gold deposits of the North-East of the USSR, attributed to the gold-quartz formation, a special morphological type of mineralization in dyke rocks.

One of the important points of geological and industrial assessment of a gold deposit is the establishment of the distribution features of mineralization. Without this it is impossible to reliably determine the density of the exploration network and, consequently, confidently make the calculation of reserves ...

Gold deposits, confined to mineralized zones of crushing and buckling of sandstone-shale strata, have specific features of structure. They differ from the widespread quartz-gold deposits of vein type not only by morphology of ore-bearing bodies, but also by the structure of ore fields confined to large discontinuous structures of deep embedment, long and complex history of mineralization development, significant scale of hydrothermally altered and mineralized rocks, predominant role of microscopic and sometimes dispersed gold in ores. If, speaking simplistically, for vein quartz-gold deposits, the problem of prospecting and subsequent exploration is reduced to finding veins and identifying areas (blocks) with balance ores in them according to the already repeatedly tested exploration network, the theoretical aspects of the methodology of exploration of gold deposits of the type of mineralized crushing zones and their practical solution still need to be developed. ...

Researchers studying the regularities of gold mineralization location within the ore fields or individual ore bodies of deposits of the ubugo-sulfide formation often encounter serious difficulties.
