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 folding of sandstone-shale sequences have specific structural features. They differ from the widespread quartz-gold deposits of the vein type not only in the morphology of ore-hosting bodies, but also in the structure of ore fields confined to large discontinuous structures of deep occurrence, the long and complex history of ore formation, the significant scale of hydrothermally altered and mineralized rocks, and the predominant role of microscopic and sometimes dispersed gold in the ores. To put it simply, whereas for vein quartz-gold deposits the problem of prospecting and subsequent exploration comes down to finding veins and identifying areas (blocks) with commercial ores in them using the already repeatedly tested exploration grid, the theoretical aspects of the methodology for exploring gold deposits of the mineralized crushing zone type and their practical solution still need to be developed. ...

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