Anticline

From petrofaq
Jump to: navigation, search

Anticline is an arch-shaped configuration of folded and stratified rock layers. It is often associated with a trap.

  1. Fold in which the layering is concave toward older rocks in the structure. An anticline contains older rocks in its centre.
  2. A geological structure sometimes described as a dome or inverted saucer. Such a structure would be an anticline with "four way dip closure" which if covered by an impermeable layer of rock would make a potential oil or gas reservoir. Not all anticlines are this "perfect" shape.
