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 ...
In Colorado it is known as the Precambrian Pikes Peak Granite. Over the next 500 million years, sedimentation (sediment deposition) occurred after the granite was produced. At about 500 to 300 million years ago, the region began to sink and lime and mud sediments deposited in the newly formed space.
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
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 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 ] The massive unconformity is due to erosion that occurred during the uplift of the modern Rocky Mountains, the Laramide Orogeny . [ 12 ]
