摘要: Identifying the geochemical anomalies from background is a fundamental task in exploration geochemistry. This research based on application of concentration–area (C–A) method at Siah-Jangal Au porphyry system southeastern Iran. Lithogeochemical datasets (n = 399) were used this survey which was conducted for mineralization. Moreover, similar surveys also carried out As, Cu, and Mo region. Anomalous threshold values mineralized zone computed compared with statistical methods data obtained chemical analysis samples lithological units. Several local scale identified (281 ppb), As (649 ppm), Cu (20 ppm). The results suggest existence that its magnitude generally above 400 ppb. C–A log–log plots show three stages enrichment. second most important enrichment event responsible presence grades have been interpreted using rather extensive set information available study area, consisting structural interpretation alteration data. Various features corresponding geologic structures play an role discrimination element distribution area.
