Dual sources of ensimatic magmas, Hearne domain, Western Churchill Province, Nunavut, Canada: Neorchean ?infant arc? processes?

Autor: Jeffrey R. Chiarenzelli, Brian Cousens, Lawrence B. Aspler

Publikováno v: Precambrian Research. 134:169-188

In the Henik segment of the Central Hearne supracrustal belt, Neoarchean supracrustal rocks accumulated in deep-water depositional systems that were well removed from a continental influence. Repeated in time and space, these systems consisted of maf

Sequence stratigraphy and evolution of the Paleoproterozoic intracontinental Baker Lake and Thelon basins, western Churchill Province, Nunavut, Canada

Autor: Thomas Hadlari, Tony D. Peterson, A N LeCheminant, Robert H. Rainbird, Lawrence B. Aspler, J. A. Donaldson

Publikováno v: Precambrian Research. 125:21-53

The Baker Lake and Thelon basins lie along the border between the Rae and Hearne domains of the western Churchill Province. Basin fill comprises the Dubawnt Supergroup, a ca. 1.85–1.70 Ga succession of predominantly continental clastic and intercal

Griffin gabbro sills (2.11 Ga), Hurwitz Basin, Nunavut, Canada: long-distance lateral transport of magmas in western Churchill Province crust

Autor: Jeffrey R. Chiarenzelli, Lawrence B. Aspler, Brian Cousens

Publikováno v: Precambrian Research. 117:269-294

Circa 2.11 Ga sills and rare dykes (herein named the ‘Griffin gabbros’) extend discontinuously across an area 400 by 125 km in the Hearne domain of the western Churchill Province in northern Canada. Sills form poorly connected, tongue-like tabula

Paleoproterozoic intracratonic basin processes, from breakup of Kenorland to assembly of Laurentia: Hurwitz Basin, Nunavut, Canada

Autor: Ira E. Wisotzek, Vicki McNicoll, Jeffrey R. Chiarenzelli, Brian Cousens, Miklos F. Losonczy, Lawrence B. Aspler, William J. Davis

Publikováno v: Sedimentary Geology. :287-318

The evolution of Hurwitz Basin records discontinuous tectonic processes in the Hearne domain (northern Canada) resulting from changing distant boundary conditions. Magmatic, eustatic and paleoclimatic influences, although significant, are considered

An introduction to Precambrian basins: their characteristics and genesis

Autor: Wladyslaw Altermann, Octavian Catuneanu, Subir Kumar Sarkar, P.G. Eriksson, D.R. Nelson, Marcelo A. Martins-Neto, Jeffrey R. Chiarenzelli, C. J. de W. Rautenbach, Lawrence B. Aspler

Publikováno v: Sedimentary Geology. :1-35

Precambrian and younger basins reflect the interaction of sediment supply and subsidence; the latter is generally ascribed to tectonic, magmatic and related thermal processes. The interplay of supply and subsidence is further modified by eustasy and

Multi-element and rare earth element composition of lichens, mosses, and vascular plants from the Central Barrenlands, Nunavut, Canada

Autor: Colin E. Dunn, Jeffrey R. Chiarenzelli, Brian Cousens, Lawrence B. Aspler, D. Ozarko, K B Powis

Publikováno v: Applied Geochemistry. 16:245-270

Lichen (n=12) and moss (n=6) species from a remote region of northern Canada have remarkably similar multi-element patterns suggesting they are non-specific accumulators of metals under existing conditions. Within individual species the concentration
