Add a one-line explanation of what this file represents
This geology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Chesapeake Crater profile view.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

Summary

[edit]

Schematic cross section of the Chesapeake Bay impact crater, showing some of its features and the location of three core holes that provided data on these features. The impact breccia fills the excavated basement rocks, surrounded by undisturbed sedimentary rocks, and overlain by post-impact sediments.
