Its unique geological structure provides valuable insights into regional tectonic evolution.

Located on the island of Oahu in Hawaii, this volcanic field consists of a layered sequence of lava flows from several volcanoes that erupted around 500,000 years ago. It features a diverse array of rock types and textures. The Koolau Volcanic Field has been instrumental in shaping the geological history of Honolulu, where many significant historical sites are located.

Located in Wales, this geological formation consists of a 400-meter-thick (1,312-foot) layered deposit from the Llandovery Period of the Carboniferous Period, approximately 420 million years ago. It is characterized by its rich fossil deposits, including those of early trilobites and other marine animals. The Llandovery Slurries have provided valuable information on ancient sea level fluctuations.

Located in Da Nang Province, Vietnam, this geological formation consists of a layered sequence of marble rocks from the Permian Period, approximately 250 million years ago. It features stunning crystal-clear formations and is used for its high-quality white marble. The Marble Mountains have been an important source of local resources and spiritual pilgrimage sites.

Located on Antarctica, this geological formation consists of a layered sequence of sedimentary rocks from the Paleozoic Era, approximately 600 million years ago. It features vast ice sheets and dry valleys that are inaccessible to most forms of plant life due to extreme cold conditions. The McMurdo Dry Valleys provide valuable insights into glaciology.

Located in Normandy, France, this geological formation consists of a 37-meter-tall (121-foot) layered sequence of sedimentary rocks from the Jurassic Period, approximately 180 million years ago. It features unique bay configurations and is home to the famous Mont Saint-Michel abbey. The bay's unusual shape provides valuable information on ancient tidal patterns.

Located in Libya, this geological formation consists of a layered sequence of sedimentary rocks from the Cretaceous Period, approximately 100 million years ago. It features diverse fossils of marine and terrestrial animals. The Oum Shrek Formation has provided significant insights into the life cycles of ancient sea creatures.

Located in Turkey, this geological formation consists of an ancient hand-drawn map that depicts the coastline and geography of the Mediterranean region from around 1500 BCE. It features detailed drawings of landmasses, islands, and coastlines. Although its cartographic accuracy remains disputed among scholars.

Located in China and Nepal, this geological formation consists of a layered sequence of sedimentary rocks from the Paleozoic Era to the Cretaceous Period, approximately 500-400 million years ago. It features some of the highest average elevations on Earth. The Qinghai-Tibet Plateau has yielded significant findings about ancient climate fluctuations.

Located in Egypt and Sudan, this geological formation consists of a layered sequence of sedimentary rocks from the Paleozoic Era to the Cretaceous Period, approximately 400-200 million years ago. It features one of the oldest divergent plate boundaries on Earth. The Red Sea Rift has provided valuable insights into tectonic evolution.
