Nettet10. apr. 2024 · The “galo” veins are surrounded by both moderately inclined joints, subparallel to the veins, and subhorizontal joints (Fig. 10d–f). Both joints sets are cross-cutting each other without any mutual displacement. The moderately inclined joints are strongly developed in the vicinity of the cupola, more so than in other parts of the mine. NettetJoints can also develop in a rock a rock under compression as a way to accommodate the change in shape (Figure 13.22). The joints accommodate the larger compression …

Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation.
