Continental rifts are the sites of significant oil and gas accumulations, such as the Viking Graben and the Gulf of Suez Rift. Thirty percent of giant oil and gas fields are found within such a setting. [23] In 1999 it was estimated that there were 200 billion barrels of recoverable oil reserves hosted in rifts.
The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American plate. It formed when the continent's core, the North American craton , began to split apart during the Mesoproterozoic era of the Precambrian , about 1.1 ...
The Afar triple junction (also called the Afro-Arabian rift system) is located along a divergent plate boundary dividing the Nubian, Somali, and Arabian plates. This area is considered a present-day example of continental rifting leading to seafloor spreading and producing an oceanic basin.
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. [1] It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor.
Researchers' new insight into the splitting process of the East Africa Rift systems show where an ocean will likely be formed if the continent's split continues.
A massive rift in Ethiopia separated continental plates by 400 feet and is part of a rift network that may flood enough to create a new ocean in 2 million years.
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
The Rio Grande rift is a north-trending continental rift zone. It separates the Colorado Plateau in the west from the interior of the North American craton on the east. [ 1 ] The rift extends from central Colorado in the north to the state of Chihuahua , Mexico , in the south. [ 2 ]
