ASBOG FG EXAM PREP 2024/2025 with 100% correct answers
Calculate the dip from 3 points of differing elevation. - ✔✔Tan(dip angle)=rise/run ; rise=high-
low point; run=map distance between high and low point.
Calculate the dip between 3 points, 2 of which are equal elevation. - ✔✔Tan(dip angle)=rise/run;
rise=high-low point; run=map distance of perpendicular line drawn from line connecting points
of = elevation to low point.
Dip-slip fault - ✔✔a fault where the movement is parallel to the dip of the fault such as normal,
reverse, or listric
Fenster - ✔✔A "window" into rocks underlying a thrust fault
Growth Fault - ✔✔A fault that forms contemporaneously with deposition in sedimentary rock.
The throw increases with depth and the sedimentary units on the downthrown side are thicker
than the corresponding units on the upthrown side
Heave - ✔✔The amount of horizontal displacement on a fault
Klippe - ✔✔An outlier of a thrust sheet completely surrounded by the exposed fault
Listric fault - ✔✔A fault with a curved fault plane. Near the surface the fault plane is steeply
dipping, but it becomes progressively flatter with depth. Listric faults may be normal or reverse.
Net Slip - ✔✔The distance between two formerly adjacent points on either side of the fault,
measured on the fault surface
Normal fault - ✔✔dip-slip fault in which the hanging wall drops down relative to the footwall;
dip between 45-90 degrees; associated with convergent plate tectonics
