GY360 Structural Geology
Structure Contour Strike and Dip Example Problem
Given the attached structure contour map of a hypothetical water table surface, calculate the
average strike and dip of the surface from points (A) and (B) on the map. To begin solv

GY360 Structural Geology Net Slip Problem
Introduction
With the attached figure and the data provided below, solve for the net slip vector for the fault
which displaces dikes A and B on the map. You can assume that the fault has a negligible
rotational co

Rotation of a data vector about an axis to a new attitude
Given the attitude of a rotational axis and the amount and sense of rotation, generate general equations
that calculate the new attitude of a data vector from its original attitude. All attitudes (

Structural Geology Resolution of Stress Problem Answer Key
Given:
1 = 50MPa
3 = 15MPa
= -35E
The above stress field is acting on rock that is cut by a structural plane that has an area of 1.0
meter2. The structural plane is oriented such that = -35E (i.e

GY403 Structural Geology Stress Problem
Introduction
For this problem use the resolution of forces method to solve for the normal stress () and
shear stress () acting on a particular plane. Remember that this plane may or may not develop
into a fracture s

GY360 Uplift Problem
Given the below information, calculate the average uplift rate of the terrane from which the
information was collected over the time span indicated.
An amphibolite sample yielded the following age dates:

GY403 Structural Geology Lithostatic Stress Problem
Given Conditions
Suppose that a 1.0 cm3 cubic block of basalt is buried to a depth of 5.0 kilometers in oceanic
crust. Assume that the overburden rock is also homogenous basalt with a constant density fr
