Fig. 12From: The northeastern Algeria hydrothermal system: gravimetric data and structural implication3D volume of the anomalies with high density. A represents the shape of anomalies with high density in the first area (a) (Fig. 3). B highlights the shape of anomalies with high density in the second area (b) (Fig. 3). The black lines represent the possible geological faults into the area, the black points represent the hot spring locations, and the red triangles represent locations of significant mineralizationBack to article page
