  This report contains instructions and patterns for preparing seven
three-dimensional paper models that schematically illustrate common earth
faults and associated landforms.  The faults described are: normal, reverse,
right- and left-lateral strike-slip, and oblique-slip.  There are also
models and discussions of two fault produced landforms, a graben and a
horst.

  These models are intended to help students and others visualize the
principal classes of faults and learn some of the terminology used by
geologists to describe faults.  By constructing and examining these models,
students will obtain a greater appreciation of the relationship between
fault displacements and the landforms that result.
