Summary
[edit]DescriptionStylolites in limestone (Lamar Limestone or Capitan Limestone, Upper Permian; McKittrick Canyon, Guadalupe Mountains, Texas, USA) 1 (37795080714).jpg |
The squiggly structures in the photo are stylolites, which are pressure dissolution features that frequently have the appearance of a hospital EKG reading. 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: probably the Lamar Limestone, Upper Permian Locality: trailside, McKittrick Canyon, Guadalupe Mountains National Park, western Texas, USA |
