Pikes Peak granite is a 1.08 billion year old Late-Precambrian geologic formation found in the central part of the Front Range of Colorado.It is a coarse-grained pink to light red syenogranite with minor gray monzogranite, and it has a distinctive brick-red appearance where it outcrops.
The Pikes Peak granite formed in several stages. In the initial stage, about 1.02 billion years ago, a large mass of magma intruded into what is now the Front Range of Colorado. Although there may have been volcanoes overlying the intrusion, the majority of the magma never reached the surface, but formed and cooled at a depth of about 1 to 2 ...
Pikes Peak (Pikes Peak granite, Mesoproterozoic) Pikes Peak is one of Colorado's 54 fourteeners, mountains more than 14,000 feet (4,267.2 m) above sea level. The massif rises over 8,000 ft (2,400 m) above downtown Colorado Springs. Pikes Peak is a designated National Historic Landmark. It is composed of a characteristic pink granite called ...
The Paleozoic era and during the Precambrian eon, about 300 million to one billion years ago, Pikes Peak Granite was formed from mass amounts of molten rock that would amalgamate, flow and combine, to form the continents. In Colorado it is known as the Precambrian Pikes Peak Granite.
English: Granite in the Precambrian of Colorado, USA Pikes Peak is a famous mountain in the American Cordillera. The correct spelling "Pike's Peak" has been suppressed. The reddish-pinkish rocks of the mountain and surrounding areas are part of the Pikes Peak Batholith, a fairly large, Precambrian igneous intrusion that was emplaced 1.08 billion years a
About 1 billion years ago, a mass of magma rose to the surface through a much older mantle, cooling to form what is now known as the Precambrian Pikes Peak Granite.Over the next 500 million years, the granite eroded with no sedimentation forming over this first uplift, resulting in a local expression of the Great Unconformity.
Throughout Colorado's geologic history, rocks have often been deformed, metamorphosed and overprinted, obscuring the ancient record. Beginning 1.7 billion years ago granite and pegmatite intruded. The Routt Plutonic Suite is dated to 1.66 to 1.79 billion years old and is an important rock formation in Rocky Mountain National Park and Buffalo ...
In the late Eocene to early Oligocene, approximately 34 million years ago, the area was a lake environment with redwood trees. The basement is the Proterozoic aged Pikes Peak Granite. There is an unconformity from the Pikes Peak Granite to the next unit, the Wall Mountain tuff. [11]
