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.
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 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 ...
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.
Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500 to 300 million years ago, the region began to sink while lime and mud sediments were ...
A major rockslide prompted two highways to be shut down in Colorado over the weekend and witnesses captured the frightening moment on video. Highways 96 and 165 from Wetmore to Westcliffe in ...
The tornado comes just over a year after an EF1 tornado with 108-mph winds hit Crystal Creek Reservoir, 4.9 miles north of Pikes Peak, on July 20, 2023. That tornado also caused tree damage and ...
