Gold grain morphology and composition in some locality composition in some locality on R.Macedonia

During the water transport alluvial gold is affected by various physical and chemical factors. It was selected three locality where was studied changes in chemical composition and morphological forms of gold aggregates: Borov Dol, Plavica and Alshar where is carried schlich prospection. Studies have shown that the size of the tested gold aggregates ranges from 30 microns to 1 mm., usually present form of gold aggregates is isometrich-irregular shape. Flakes-flattened shape also quite prevalent as elongated for. .Gold aggregates in a Borov Dol as a whole is characterized by constant chemical composition, more exactly, it is homogeneous and high grade almost everywhere with purity that ranges from 834 to 981st In Alshar despite the presence of gold in chemical analysis, with schlich prospection were not discovered gold aggregates. Key words: schlich prospection, placer gold, morpology, high-gold grai
