Fault patterns in the area just
south of Orella Road, Ogallala National Grasslands - Summer 2004.
Below is a suggested question outline - you
can and should adapt it, reorganize, revise it.
- What is the larger project this report is
a part of?
- Where is this study area?
- Why might these faults be of interest?
Previous work and background:
- What is the stratigraphic unit the faults
occur in here?
- What have other researchers said about faulting
and tectonism in this area?
- In general, how do faults form/grow?
- How, when and by whom was the data collected?
- How has the data been plotted, analyzed and
- What might be biases in the data?
- What are preferred orientations the faults
- What types of geometries do they show (e.g.
en echelon, splays, characteritistic length, etc.)?
- What type of minerals and textures do you
see in the fault rocks?
- How do the fault attributes change along
- What patterns in fault characteristics can
be seen spatially (spacing, facing, etc.)?
- If there are any cross cutting relationships,
which fault trend is older and which is younger?
- How do these faults compare with others mapped
in the area?
- How do they compare orientation wise to regional
tectonic trends (e.g. Wyoming-Colorado lineament, Black Hills
- How do these faults compare in orientation
to the veins in the area?
- What do the observed fault geometries suggest
about the history and mechanics of fault formation?
- Is there any constraint on the age of faulting?
- What work could be done in the future to
- What are the three to four main points the
reader should take away with them?
- Illustrative photos/ sketches of fault geometries.
- Rose diagram of fault orientations.
- Map showing fault positions and orientations.
- Diagram/photos showing along the fault changes.
