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 ]
Texas has been the leading state in petroleum production since discovery of the Spindletop oil field in 1901. [11] As of October 2017, the State of Texas (if treated as its own nation) is the 7th largest oil producing nation in the world, with production totaling approximately 3.78 million barrels (600 thousand cubic meters ) per day of oil ...
The Permian Basin covers more than 86,000 square miles (220,000 km 2), [1] and extends across an area approximately 250 miles (400 km) wide and 300 miles (480 km) long. [2] The Texas cities of Midland, Odessa and San Angelo serve as headquarters for some of the oil production activities in the basin.
The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all, active rift systems. Major rifts occur along the central axis of most mid-ocean ridges , where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates .
Lake-filled half-graben showing sedimentation dominantly from the 'hinge' margin. Four zones of sedimentation can be defined in a half-graben. The first is "escarpment margin" sedimentation, found along the major border faults bounding the half graben, where the deepest part of the basin meets the highest rift-shoulder mountains. [6]
The marker was created in 1840 and placed in 1841 to mark the international border between the United States and the Republic of Texas. The survey which established this border lasted from May 1840 to June 1841; the survey team faced hazardous, swampy conditions in their work and were forced to take several extended breaks due to weather and a ...

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 ...
