The record and stratigraphie implications of organic-walled microfossils from the Ediacaran (terminal Proterozoic) of South Australia - Volume Issue 4 - Richard J. F. Jenkins, David M. McKirdy, Clinton B. Foster, Teresa O'Leary, Stephen D. Pell. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The Paleoproterozoic Thelon Basin in Nunavat, Canada, is one of several large quartz-dominated sedimentary basins devel-oped on Paleoproterozoic and Archean rocks of the Canadian Shield. Coarse-grained quartz to sub-feldspathic sandstones and conglomerates of the Thelon Formation comprise the basin fill.
13 these nuclei contains one or more sedimentary basins (or metasedimentary basins) of Proterozoic age. This paper 14 provides an overview of each of the cratons and a brief description of the Precambrian sedimentary basins in India 15 that form the focus of the remainder of this Size: 1MB. Geological Setting. In the Proterozic, this area was located on the west coast of ancient North America. The thick sedimentary deposits composed an eastward tapering, supracrustal wedge. At least three cycles of basin formation and extension at the western edge of Laurentia resulted in 22 kilometers of sediment deposited in the early Proterozoic through to the Paleozoic y: Canada.
The Proterozoic Biosphere is the first major study of the paleobiology of the Proterozoic Earth. It is a multidisciplinary work dealing with the evolution of the Earth, the environment, and life during the forty percent of Earth's history that extends from the middle of the Precambrian Eon ( Ma) to the beginning of the Paleozoic Era ( Ma.). Classification of basins, with special reference to Proterozoic examples P. A. ALLEN1, Secondly, this paper uses mainly Proterozoic basins from a set of specific cratons (Kaapvaal craton, Canadian shield, Brazilian shield, Australian continent and and the detailed basin studies making up the core of the book, it would have been.

Proterozoic sedimentary basins at the margin of Archean cratons are repositories of detritus not only from multiple cratonic domains but also from cratonized orogenic belts that become integral parts of continental clusters stitched at different ages and bear records of multiple tectonic pulses.

The Precambrian sedimentary basins were developed on four major Archaean nuclei (Dharwar, Bastar, Singhbhum and Aravalli–Bundelkhand; Fig. ) and are comparable to those of Australia, South Africa, Canada and Brazil in scale and importance for global studies of Precambrian crustal by: 6.

Geological Survey of Canada Paper pp. 25– Google ScholarCited 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.
A wide variety of such forms are described from the Proterozoic successions of India viz., the Vindhyan, Chhattisgarh, Kurnool and Bhima basins in peninsular India and some of the carbonate belts of the Lesser Himalaya.

The composition, sedimentary structures, and geometry of these sedimentary packages indicate that large stable continents existed at the time of their by: 7. Some of the deposits have high concentrations of other metals, including nickel, arsenic, cobalt and gold. Ubiquitous chlorite and clay alteration is characteristic of the Proterozoic basins in Canada of similar ages and having analogous geological.
Proterozoic Sedimentary Basins. Vindhyan Basin Cuddapah Basin Kurnool Group. INTRODUCTION A number of nearly flat-lying, virtually unmetamorphosed and partly deformed proterozoic cratonic basins forms a significant part of the Precambrian shield of India. These basins predominantly contain orthoquartzite, shale, carbonate suites varying in thickness form to 10, m and deposited 5/5(1).
The Windermere Group rocks — also mostly clastic sedimentary — were deposited in the ocean along the western edge of Laurentia (Figure ) in the late Proterozoic (around Ma) after the breakup of Columbia. In fact, sedimentary rocks of this age extend all along the western side of the Rocky Mountains, Author: Steven Earle.
Ramps generally formed in Proterozoic extensional and foredeep basins, and often preceded development of rimmed shelves in more stable, possibly thermally subsiding basins.
Rimmed shelves locally formed margins with as much as 1, m of relief relative to the adjacent basin and contained stromatolitic barrier reefs that were extensive for.
