Abstract
Porphyry copper-molybdenum deposit is an important copper-molybdenum ore deposit in China. Chehugou porphyry copper-molybdenum deposit is located at the edge of North margin uplift, in Chifeng-Kaiyuan deep fractures on the top of a prominent curved to the North of Chifeng. The main ore rock is granite porphyry, porphyry normal, hidden breccia, which has a wide distribution. The ore enrichment is closely linked to alteration. The main bonanza is the hidden breccias after second enrichment. Major alteration types are silicification, potassic, muscovite-oriented, sericitization, carbonation, and pyrite. Ore structures comprise disseminated structure, vein-like structure, cemented breccia structure, and lump structure. Based on existing geological data analysis, by combined with field investigation, the paper analyzes and discusses the relationship between characteristics of al-tered wall rock alteration and mineralization.关键词
