THIN AND DISPERSED GOLD MINERALIZATION IN THE NORTH-WESTERN BLACK SEA COAST
Gold was studied from coastal-marine and river sediments on the north-west coast of the Black Sea. In the upper parts of alluvial deposits gold has a small impurity content, and forms thin plates with clear contours which are composed influxes, colomorphic aggregates with a multitude of voids. In the lower section of alluvium deposits are dominated dense lumpy, often deformed grains of gold with silver and other impurities. These features of gold to some extent can explain the regional problems of its identi- fication and enrichment.
Keywords: alluvium, gold association, morphology of gold.
