| concepts from chapter 2 |
|
|
| |
These exercises explore concepts from Chapter 2 including
the gnomonic and Mercator projections, 2- and 3-dimensional transformation
of coordinates, and use of the equal angle stereonet to plot the orientations
of planar and linear structural elements. |

|
| mapping dikes at Ship Rock |
|
|
| |
This exercise introduces the position vector for mapping
geological contacts and the translation and rotation of a local coordinate
system to a map with standardized coordinates. The thickness variations
along a dike also are examined to investigate physical mechanisms
operating during emplacement of the magma. |

| mapping faults at Chimney Rock |
|
|
| |
In this exercise we consider basic concepts and tools
for mapping geological structures and for analyzing the orientations
of linear and planar structural elements. Both structural maps and
stereographic projections are prepared using ten data sets for faults
from Chimney Rock, Utah. The spherical variance is used to evaluate
the clustering of orientation data. |

|
| kinematics of faulting at Chimney Rock |
|
|
| |
The kinematics of faulting are examined at Chimney Rock,
Utah. Slickenlines on exposed fault surfaces are used to analyze the
direction of slip and to investigate how these directions vary along
a fault. Structure contours are constructed from GPS data for the
Carmel and Navajo formations and these are used to identify faults
and to measure the magnitude of slip. |
