Effect of Small Thrust Faults on Cave Passage Cross-Section
Eberhard Werner

Abstract

Thrust faults whose displacement may be measured in centimeters and whose lateral extent may be a few hundred meters are very common in caves along the eastern edge of the Allegheny Plateau of West Virginia. These faults exert control over cave passage cross-section. Usually, the cave passage becomes slightly less in height and very much greater in width where the faults interesect the passage. Sometimes, there is an accompanying increase in breakdown.
