Joel's Ph.D. thesis, Structure and metamorphism of the Grand Forks Complex (GFC), British Columbia aims to integrate a number of geologic disciplines to construct a tectonic model for the GFC, while addressing a number of specific problems, including 1) quantifying displacement on the bounding normal faults, 2) unraveling polyphase folding. Paleogeographic reconstructions for the US portion of the margin and for northern British Columbia and Yukon reveal the interpreted presence of offshore terranes and arcs (see Miall and Blakey ), but these did not significantly affect southern British Columbia until their arrival at the continental margin after about Ma. An important outcome of MDRU’s Yukon Gold Project was a published manuscript in the journal Interpretation by Sánchez et al., that identified regional lineaments in the poorly exposed western Yukon and eastern Alaska, and identified their associations with epigenetic mineral occurrences. eds., Tectonic Growth of a Collisional Continental Margin: Crustal Evolution of Southern Alaska: Geological Society of America Special Paper , p. –, doi: /(16).

Get this from a library. Tectonic framework of Southern Yukon and Northwestern British Columbia. [Hubert Gabrielse; Geological Survey of Canada.]. This paper briefly describes the geological framework of Yukon south of 65 degrees N and, with some exceptions, uses the Tectonic Assemblage Map of the Canadian Cordillera (Wheeler and McFeely ) and the Terrane Map of the Canadian Cordillera (Wheeler et.
The distribution of mineral deposits within northwestern North America (Alaska, Yukon, and northern British Columbia) allows for an in-depth examination of the metallogenic patterns of a growing continental margin.
A more complete understanding of the tectonic evolution of this part of the Pacific Rim, achieved over the last 15 to 20 years, now allows for the placement of ore systems into a. This activity aims to establish an new tectonic framework for the oceanic crust in the Cache Creek terrane in southern Yukon and northern British Columbia.

A variety of geologic, paleomagnetic, and paleontologic evidence indicates that these rocks have been displaced considerable distances from their Cited by: The Llewellyn fault and Tally Ho shear zone region of northwestern British Columbia and southern Yukon is the locus of a series of vein-hosted gold prospects and deposits, including the past.
The closure of the Cache Creek Ocean during the Jurassic led to the structuration of the Canadian Cordillera. To reassess the timing of this major tectonic event, this study proposes a biochronological review of all the youngest radiolarian-bearing localities of the Cache Creek Terrane in British Columbia and Yukon using updated radiolarian biozonations and taxonomy, complemented by new data.
Quantitative analysis of tectonic subsidence mainly for strata of Cambrian and Ordovician age between British Columbia and eastern California indicates that thermally driven subsidence of the passive margin began after about Ma, that is, in latest Proterozoic or Early Cambrian time, and this is corroborated by limited stratigraphic evidence.
The high-grade ( million ounces of gold; Mt grading g/t Au; Pretium, ) Brucejack epithermal Au-Ag deposits are located in the Canadian Tectonic framework of southern Yukon and northwestern British Columbia book of northwestern British Columbia, and formed in association with extensive early Mesozoic island arc magmatism.
accretion to North America along the Omineca tectonic welt and the Insular terranes joined and accreted together along the Coast tectonic welt. This was followed by a series of studies that showed: 1) Yukon-Tanana terrane was a fragment of the continent margin that rifted away in the Devonian (Mortensen, ); 2) Slide Mountain terrane was a late.

Our reconstructions support a “northern option” Farallon ridge geometry and allow up to ∼ km Chugach terrane translation since Paleocene time, providing a new “tomographic piercing point” for the Baja-British Columbia debate.
The Northern Cordilleran Volcanic Province (NCVP), formerly known as the Stikine Volcanic Belt, is a geologic province defined by the occurrence of Miocene to Holocene volcanoes in the Pacific Northwest of North belt of volcanoes extends roughly north-northwest from northwestern British Columbia and the Alaska Panhandle through Yukon to the Southeast Fairbanks Census Area of far.

British Columbia (BC), southern Yukon and Northwest Territories, and adjacent western Alberta contain immense northwestern corner of the Horn River Basin (Figure 4). Due to sampling bias, the densest region shown by the tectonic history will provide a framework for determining the thermal history and the timing of hydrocarbon genera.
The tectonic framework of China, from north to south, consists of four major domains: 1) the Altaids orogenic collage (including Manchurides) or Central Asian Orogenic Belt; 2) the Tarim–North China Craton or intermediate units; 3) the Tethysides; and 4) the Nipponides along the Pacific margin to the east (Fig.
2, Fig. 3, Fig. 4; Li et al. evolution. New field and laboratory studies of the Kechika group, south-central Yukon, were conducted to test these rift models and constrain the timing and tectonic setting of post-breakup magmatism. The Kechika group contains vent-proximal and sediment-sill facies that developed outboard of continental margin shelf and trough basins.
Annette, Gravina, Duke, and southern Prince of Wales Islands belong to the Alexander terrane, which is a coherent tectonic fragment that underlies much of southeastern Alaska and the Saint Elias Mountains region of British Columbia and Yukon.
