Summary
editDescriptionBasalt gravel in tidal pool (Yaquina Head, Oregon, USA).jpg |
English: This is a tidal pool along a rocky shoreline at Yaquina Head, Oregon. The bedrock flooring the tidal pools in the area is the Ginkgo Basalt, one of many lava flows in the Miocene-aged Columbia River Flood Basalt. The black clasts in this tidal pool have eroded from the Ginkgo Basalt.
Flood basalts are vast outpourings of lava from one or more large fractures in the crust. This rare type of volcanism is not occurring on Earth at present, but ancient flood basalt provinces that can be examined - for example, the latest Cretaceous-aged Deccan Traps of India and the latest Permian Siberian Traps of Russia. Flood lavas are also known on Mercury, Venus, and the Moon. Locality: tidal pool on the southern side of Yaquina Head, coastal Oregon, USA Info. at: www.usgs.gov/observatories/cvo/columbia-river-basalt-grou... |
