Abstract: For purpose of find out the metallogenic regularity of the broken and altered deposit in Duoergongma area, which is controlled by fault fracture zone, verification methods were adopted, such as soil geochemical survey, 1∶10,000 comprehensive profile survey and trough exploration, and studied the characteristics of element distribution, element correlation and element anomaly. (1) Sb and Au are the dominant ore-forming elements with great metallogenic potential, and As, Cu, Pb, Zn, Ag are the important ore-prospecting indicator elements closely related to Sb and Au mineralization. (2) Four broken alteration veins of altered rock type have been discovered, and three antimony industrial orebodies have been delineated. (3) It is preliminarily identified that this area is mainly a broken alteration rock type antimony-gold deposit controlled by fault fracture zone. Combined with the metallogenic conditions and abnormal development of the mining area, it is suggested to carry out 1∶10,000 soil survey in the periphery to expand the prospecting results.
