Summary
[edit]DescriptionStylolite in limestone (Brassfield Formation, Lower Silurian; Fairborn, Ohio, USA) 2 (26735361019).jpg |
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. Stratigraphy: Brassfield Formation, Lower Silurian Locality: eastern wall of Oakes Quarry Park, east of the town of Fairborn, northwestern Greene County, western Ohio, USA (39° 48' 47.75" North latitude, 83° 59' 01.50" West longitude) |
