New Interpretation of the Lithogeochemical Data from the Alsar Epithermal Au-Mineralized Area

By Todor Serafimovski, Blazo Boev and Goran Tasev


The paper presents a new approach to the interpretation of the geochemical data obtained from samples collected in the wider vicinity of the AlSar deposit. The authors use the results of 288 samples analyzed in the laboratories of the NASSAU Company, USA, during the time period from 1986 to 1989. Gold with average contents of 0.55 ppm Au was found in 156 samples. The lowest anomaly amounts to 0.31 ppm Au and varies from 0.034 ppm to 19.64 ppm Au. The interpretation of the present authors showed that data falls mainly in three major points which follow the fractures of north-northeast.- south-southwest strike orientation. A study of the correlation relationships between Au and other accompanying elements indicated good relationship between Au and Sb, in places between Au and As where high correlation coefficients were found between Au and Sb. Those of I Ig and Ag are very low and no pertinent correlation between Au and Hg and Au and Ag were found. Three-dimensional presentation of Au contents in the Alsar deposit defines the hypsometric distribution whose highest Au concentrations were found between peaks 800 m and 823 m
