Study Notes
Sedimentary Rocks and Basins Summary
- Organic-rich shales are the main source of oil and gas in sedimentary rocks.
- Ooidal limestones are composed of spherical grains of calcium carbonate precipitated around a nucleus in shallow tropical seas.
- Lithification is the process by which sediments are transformed into solid rocks.
- Oceanic basin is not mentioned as an example of a sedimentary basin in the text.
- Strike-slip basins are created by a step in a transform fault.
- Sediment supply for rift basins comes from adjacent basement highs.
- Clastic sedimentary rocks form in quiet water settings, and organic-rich shales are the source of oil and gas.
- Diagenesis is the main process by which sediments are transformed into solid rocks.
- Biochemical sedimentary rocks form in shallow, warm waters where invertebrate animals live and absorb calcium carbonate to form their skeletons.
- Chemical sedimentary rocks are formed through the precipitation of calcium carbonate around a nucleus in shallow tropical seas.
- Syn-rift basins are created by extension perpendicular to their orientation.
- Lithification is the main process by which sediments are transformed into solid rocks.
