The geophysical field of the Dachang ore field displays gravity low combi-ned with ringed magnetic anomalies as its macroscopic character, which is anindication of the ore fie1d composed of concealed granite of high-level empla-cement and its thermal metamorphic zone; microcosmically, this field showsgravity outward convex combined with superimposed magnetic anomalies or IPanomalies, which is an indicator for ore deposits of different types and atdiverse denudation levels. An investigation of these indicators seems to be ofsignificance in looking for concealed ore deposits in a metallogenic area or belt.
