A typical Stylolite in Limestone

Summary[edit]

Description

The structure shown above is a stylolite, a pressure dissolution feature that frequently has the appearance of a hospital EKG reading. These occur in many limestones, dolostones, and marbles, especially in or near orogenic belts.

The host rock here is limestone, a biogenic sedimentary rock composed of calcite (CaCO3 - calcium carbonate). Most limestones form in ancient, warm, shallow ocean environments.
