Faults

This slide show contains a series of field photographs of the wide variety of features commonly referred to as "faults" (this is actually naming, not describing the feature). The field photographs are intermingled with some textbook sketches, maps and illustrations. It is recommended that you read this document to familiarize yourself with the terms used to describe the photographs
