Abstract：Knowledge of the porphyry Cu (Mo) ore belts in the Central Asian metallogenic domain originates from the division of the peri-Balkhash-Ili volcanic-intrusive belt in Kazakhstan and confirmation by the geophysical field. Through the definition of the Kazakhstan-Junggar ring-shaped magnetic anomaly zone, the authors lay a geophysical foundation of the porphyry Cu (Mo) ore belts of the Central Asian metallogenic domain and recognize their coupling relation to the volcanic-intrusive belts at peripheries of the Kazakhstan-Junggar block. On that basis, an embryo of the porphyry Cu (Mo) ore belts in the Kazakhstan-China-Mongolia Central Asian metallogenic domain is established.
