South Lancangjiang metallogenic condition is superior, the volcanic arc metallogenic belt has been praised by geologists, the north district of Guanfang, Wenyu copper prospecting research has made important progress in recent years, the paper study in the Hongdoushan mountain copper deposit (the newly discovered deposits) by tectonic geochemical for the first time, points out the deep prospecting direction, speculated that there may be a porphyry deposit in the deep. The level of 1272m and 1220m were studied by using the method of tectonic geochemistry. Delineated mineralization elements combination anomalies by type R cluster analysis and factor analysis results; The abnormal distribution in the altered rock, controled by NE-trending F1 fracture and NWW-EW-trending F3 fracturein the mining area, Through fracture to surrounding rock appears anomaly zoning phenomenonin of high temperature to low temperature, indicating that the migration of ore-forming fluid direction, orebody occurrence information, provide an important basis for deep prospecting prediction; Engineering verification of anomaly area and deep ore-prospecting target obtained the better prospecting effect.
