Abstract
The Lojane deposit is a characteristic epithermal As-Sb type of mineralization located in the contact boundary between the Tertiary volcanites and the Jurassic ultrabasites in the immediate vicinity of the village of Lojane in the northern parts of the Republic of Macedonia. Mineralization is of a vein type, and the main bearers of As-Sb mineralization are the stibnite (antimonite) and the realgar, followed at the places by the orpiment. Four morphological types of mineralization are defined by the latest macroscopic and microscopic investigations of the Lojane As-Sb mineralization. The first type is defined as the realgar and the realgar-orpiment mineralization in the silicified breccias.
The second type is characterized by purely stibnite mineralization in the silicified breccias. The third type of mineralization is massive to earthy, realgar type occasionally interspersed with later feather-like stibnite veins. The fourth type is characterized by the
most common stibnite veins and realgar-stibnite veins. Beside the defined four morphological types of ores in the Lojane deposit, there are transitional types among these mineralizations, usually followed by ore nests, brecciated ores with impregnations, ores in crushing zones, and veinlets with impregnations. The concentration of the mineralization is the most intensive within the individual or complex ore veins, which in places
transform into lenses or in brecciated zones. The average content of the main ore components in the Lojane deposit is about 4% Sb and 5% As.
