Proterozoic Era The Proterozoic Era, also termed the Algonkian, is the second of the two eras into which the Precambrian has traditionally been divided. The Precambrian includes over four fifths of Earth's history: the billion years from the formation of Earth to the start of the Cambrian Period some million years ago. The first half of the Precambrian is known as the Archean Era and.

ACCORDING TO THE LAKE HURON SHEET (Map A) of the Geological Survey of Canada, rock formations of Proterozoic age in the general vicinity of Sudbury and Española are represented by the Huronian (Bruce and Cobalt series), Whitewater series, acid intrusives of Killarnean age, and basic intrusives of Keweenawan age. Interest in ore deposits persisted and there was an increasing interest in interpretation of the tectonic history of Proterozoic rocks in terms of plate tectonic models, as summarized in papers by Phillip Anderson, Ed DeWitt, Clay Conway, Paul Lindberg, and J.L Anderson in the Arizona Geological Society Digest “Geologic Evolution of Manufacturer: Arizona Geological Society. In the early Proterozoic approximately billion years ago, Eukaryotic cells (cells with nuclei) appeared for the first time. Marine algae and bacteria also evolved early in the era.

Diabase dikes and sills were intruded during a Late Proterozoic phase of extensional tectonics in the northern Canadian Cordillera.

By analogy with other Proterozoic and Phanerozoic depositional basins, the sedimentary and tectonic history of early Proterozoic rocks of the northern Great Lakes area is tentatively interpreted in terms of the aulacogen model; a corollary of this interpretation is that the aulacogen opened into an ocean lying somewhere to the east, in the area.

Tectonic setting is the principal controlling factor of lithology, chemistry, and preservation of sediment accumulations in their depocenters, the sedimentary basins. The latest classification of Ingersoll and Busby () assigns sedimentary basins into five major groups based on their relationship to plate boundaries (Figure 4).It groups together the basins that are associated with the.

The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments.

The early Proterozoic Huronian Supergroup of the north shore of Lake Huron (Fig. 1) is a thick (up to 12, m) succession of sedimentary and volcanic rocks deposited between about 2, and Cited by: The Proterozoic (/ ˌ p r oʊ t ər ə ˈ z oʊ ɪ k, p r ɒ t-,-ər oʊ-,-t r ə-,-t r oʊ-/) is a geological eon spanning the time from the appearance of oxygen in Earth's atmosphere to just before the proliferation of complex life (such as trilobites or corals) on the name Proterozoic combines the two forms of ultimately Greek origin: protero-meaning "former, earlier", and -zoic.

Proterozoic Eon, the younger of the two divisions of Precambrian time, the older being the Archean Proterozoic Eon extended from billion to million years ago and is often divided into the Paleoproterozoic ( billion to billion years ago), the Mesoproterozoic ( billion to 1 billion years ago), and the Neoproterozoic (1 billion to million years ago) eras.

and styles of Early Proterozoic tectonism in southwestern North America. INTRODUCTION More than 50% of the present crust of North America was assembled in the period Ga. Studies of the development of early Proterozoic orogenic belts are therefore essential for understanding the history and mechanisms of continental growth of North America.

Energy in the depositional environment: The first key to the identification of sedimentary facies and environments is the relationship between energy and clast size. Generally, the higher the energy (that is, the faster the wind or water is moving) the larger the grains that can be kept in suspension.

Early tectonic models of Proterozoic lithosphere envisaged that the Archean cratons were subdivided by mobile belts in which deformation was wholly ensialic, with no rock associations that could be equated with ancient ocean basins.

These interpretations where Pro-terozoic orogenies occurred far from continental margins have since fallen out of favor. characterizing the Proterozoic Era, especially those related to the significant tectonic changes that occurred during the Late Archean—Early Proterozoic Eras.

The interaction of tectonic, biogeochemical, and climate processes, as described in this paper, resulted in the establishment of habitable environments that fostered the Ediacaran and early Phanerozoic radiations of animal life and the emergence of complex, modern-style ecosystems.

This first involved the amalgamation of the West Australian and North Australian cratons, followed by collision with the South Australian by: More than 3 km of late Proterozoic predominantly siliciclastic strata were deposited in this basin in southeastern Idaho, western Utah, and eastern Nevada prior to continental separation in the latest Proterozoic or Early Cambrian, and represent a variety of depositional environments including basinal marine, shallow marine, braid delta.

Most detrital sediments are continental or transitional, and most chemical sediments are marine. Plate tectonics provides the linking framework for all tectonic and magmatic activity seen today, but it is not known when plate tectonics first developed on Earth.
