Precambrian - Precambrian - Precambrian geology: By international agreement, Precambrian time is divided into the Archean Eon (occurring between roughly billion years ago and billion years ago) and Proterozoic Eon (occurring between billion and million years ago).

After the Precambrian, geologic time intervals are commonly subdivided on the basis of the fossil record. Chapter An Overview of the Geology of the Barberton Greenstone Belt and Vicinity: Implications for Early Crustal Development Donald R.

Lowe, Gary R. Byerly Pages   The Eoarchean Nuvvuagittuq greenstone belt in eastern Canada with rocks as old as Ga (Table 1, no. 1) represents the oldest one among these North American greenstone belts (O'Neil et al., ). The recent detrital zircon dating of quartzites and quartz-schist in this belt has yielded the ages around Ga age (Cates et al., Cited by: Precambrian rocks are exposed in approximately one-third of the km2area of the Pecos greenstone belt.

They are overlain unconformably by as much as m of Paleozoic carbonate and clastic rocks in the remaining two-thirds of the area (fig.

The Abitibi greenstone belt is of outstanding economic importance as it contains some of the most important gold and base metal mining camps in Canada, with a total endowment of over million metric tonnes (Mt) of polymetallic massive sulfide ore (Mercier-Langevin et al., ) contained in volcanogenic massive sulfide (VMS) deposits and over 4, t of gold (Dubé and Gosselin,   Stott, G.M., Morrison, D., The geology and tectonic sequence of events in the south-central Onaman-Tashota greenstone belt, east Wabigooon Subprovince.

These deposits are mined in the Superior Province’s Abitibi greenstone belt and are rich in magnetite (Taner and Dickens North American Precambrian geology.

Precambrian - Precambrian - Age and occurrence of greenstone-granite belts: Greenstone-granite belts developed at many different times throughout the long Archean Eon.

The Isua greenstone belt in West Greenland is about billion years old. In the Zimbabwean craton, they formed over three successive periods: the Selukwe belt about to billion years ago, the Belingwean belts about 2.

Greenstone belts are zones of variably metamorphosed mafic to ultramafic volcanic sequences with associated sedimentary rocks that occur within Archaean and Proterozoic cratons between granite and gneiss bodies. The name comes from the green hue imparted by the colour of the metamorphic minerals within the mafic rocks: the typical green minerals are chlorite, actinolite, and other green.
