English term or phrase:grade into
The conceptual geological model of the XXX deposit is a multi-phased intrusive complex. At least four generations of intrusive units and mineralizing events have been identified, the last one producing extensive mineralized magmato-hydrothermal breccias. The alteration pattern is dominantly phyllic with overprinted potassic zones. Potassic alteration *** grades into *** propylitic alteration with lower metal values along the margins of the mineralized system.
