a)
The type of dip-slip fault shown in Diagram 1 and the dominant force during faulting.
a)
Answer to Problem 1GST
Diagram 1 is showing a reverse fault and compressional stress is the dominant force during the faulting.
Explanation of Solution
“A fault is a fracture or a zone of displacement of rock masses relative to one another along a fracture. The rock above a fault plane is the hanging wall block and the rock below the fault is the footwall block.”
Diagram 1 is a reverse fault. A reverse fault occurs when the hanging wall block is uplifted along the fault surface with respect to the footwall; the responsible stress factor is compressional stress which creates folds along colliding plates. It may result in the horizontal shortening of crustal rock blocks.
b)
The type of dip-slip fault shown in Diagram 2 and the dominant force during faulting.
b)
Answer to Problem 1GST
Diagram 2 shows a normal fault and tensional stress is the dominant force during the faulting.
Explanation of Solution
“A fault is a fracture or a zone of displacement of rock masses relative to one another along a fracture. The rock above a fault plane is the hanging wall block and the rock below the fault is the footwall block.”
Diagram 2 is a normal fault. A normal fault occurs when the hanging wall block slips down along the fault surface with respect to the foot wall; tensional stress is the factor responsible for causing the formation of a normal fault. This stress pulls the rock masses apart and breaks them to cause a normal fault.
c)
The match of a correct pair of arrows in Diagram 3 to the faults in Diagrams 1and 2.
c)
Answer to Problem 1GST
Pair “a” represents Diagram 1 and pair “b” represents Diagram 2.
Explanation of Solution
“A fault is a fracture or a zone of displacement of rock masses relative to one another along a fracture. The rock above a fault plane is the hanging wall block and the rock below the fault is the footwall block.”
The matching pair of arrows with Diagram 1 is pair “a”; a reverse fault.
The matching pair of arrows with Diagram 2 is pair “b”; a normal fault.

During your fieldwork, you discovered a shear zone (SZ) with a general attitude of 0°/90°, approximately 1 km long and 2 m wide, which occurs over very weathered rocks with a schist appearance and contains quartz veins and veinlets with boxworks showing Fe oxides (see figure). The chemical analyses of the samples you collected gave interesting values of 6 to 14 ppm of Au. Your boss, very free, asked you to prepare a quote for the execution of an exploratory drilling hole for two different orientation conditions (60° and 70°) in order to investigate: the continuity of the mineralization at depth, what the host is and whether there is also mineralization on both sides. For this, your boss will tell you that the hole should intercept a ZC 100 meters below the surface, where the rock will certainly be fresh, and that the entire hole should be chemically applied.…arrow_forward
