Preliminary Precambrian basement map of Colorado-- - USGS
Nearly all the metalliferous deposits are of post-Precambrian (Phanerozoic) age, having formed in Laramide and mid-Tertiary times; but it has been shown that ductile shear zones formed in the Mesoproterozoic (1.4 billion years ago, Ga) were important in localizing younger intrusions and genetically related ore deposits, especially those in the Colorado mineral belt (Tweto and Sims, 1963).

The bulk of many of the world’s valuable mineral deposits (for example, those of gold, nickel, chromite, copper, and iron) also formed during the Precambrian. These concentrations are a reflection of distinctive Precambrian sedimentary and magmatic rocks and their environments of formation.

The Colorado Mineral Belt Revisited--An Analysis of New Data ABSTRACT New geologic and geophysical data extend our knowledge of the complementary role of inherited zones of weakness in Precambrian basement and Late Cretaceous-Tertiary magmatism in development of the Colorado Mineral Belt (COMB).
Chapter 5 - Precambrian Basement
The Precambrian basement is poorly known under deeper, and several shallower, parts of the basin. However, some of the shallower portions, particularly in northern Manitoba, have been actively explored by mining companies.
Gravity and Magnetic Investigations into Possible Economic ...
The economic ore deposits specifically in the Pea Ridge Mine in Washington County contain known economic minerals and rare earth element deposits. In order to further investigate the Precambrian basement lithologies and the possible locations of additional economic ore deposits, a gravity survey was conducted during the summers of 2013 and 2014, collecting over 700 new gravity stations.

These also are the ages of the two main groups of rocks that comprise the Precambrian basement under the San Juan volcanic area. Although the data from the western San Juan caldera complex scatter considerably, the only obvious source for the lead seems to be the 1,700- to 1,800-m.y.-old rocks or detritus of such age in Phanerozoic sediments.
Economic geology - Wikipedia
Economic geology is concerned with earth materials that can be used for economic and/or industrial purposes. These materials include precious and base metals, nonmetallic minerals, construction-grade stone, petroleum, natural gas, coal, and water. Economic geology is a subdiscipline of the geosciences; according to Lindgren it is “the application of geology”. Today, it may be called the scientific study of …

Dec 22, 2012 · The Precambrian exposures are of interest to Coloradans since the rocks contain large deposits of iron, both banded iron formations and specular hematite. Iron was first produced from the Sunrise mine, and later the Chicago, Central, and Good Fortune mines, near the towns of Hartville and Sunrise in the late 1800’s.

In the Penokean Province, a taconite body, located about 3 miles west of Matlock, Sioux County, is flanked by serpentinite that contains traces of chromite and nickel sulfide. Also, layered-type orthomagmatic titaniferous magnetite deposits are located at Osborne, Clayton County, and Spencer, Clay County.
