I like the expression “rock record.” For me, these two words encapsulate Earth’s readable history, page by page. These include rock willow (Salix vestita), bog willow (S. pedicellaris), and Labrador willow (S. argyrocarpa), as well as naturally occurring hybrids between S. arctica and S. It was at this juncture that Nero, my 4 Dr. Leith, who is a well-known authority on the geology of northern Minnesota and Michigan, made [9], The main wildlife consists of belugas, walrus, caribou, common eiders and snowy owls all of which can be seen on the island year round. In 1941, a religious movement led by Charley Ouyerack, Peter Sala and his sister Mina, caused the death by blows or exposure of nine persons.[6][7]. 30 . The obvious answer, proposed in the 1950s, is that it’s the remnants of a large impact crater. The islands are composed of folded rock. Large deposits of iron ore underlie the Belcher and neighbouring Nastapoka islands. Figure 10.2 Representative Drill Section for 2011 Program. Basin instability and basic volcanism Although they appear delicate, the Belcher Islands are actually composed of tough rock that has survived unimaginably long stretches of geologic time. New Glasgow and Belcher Islands Eskimoes, 16 mm, 1920’s Depostor Therrien Coll., Number NFA 76-9-25; deposited Jan 1975 Sanford, B.V.; Operation Winisk, may have reference to WWII and Belcher; 1969 The 1,500 islands making up Belcher Islands are spread over an area of about 3,000 square kilometres. The group, first sighted by the English navigator Henry Hudson in 1610 and named for Sir Edward Belcher, who commanded an Arctic expedition in search of Sir John Franklin, was not explored and mapped until 1915. On the southeast corner of Hudson Bay, the coast line traces a near perfect arc, roughly concentric on another ring of islands in the bay. What is the world’s largest archipelago? The Belcher Islands (Inuit: Sanikiluaq)[1] are an archipelago in the southeast part of Hudson Bay. From Henry Hudson's 1610 logbook, he likely sighted the islands prior to the mutiny of his crew. The effusive volcanic facies are made up of thick, massive lava flows, some of which are compound, that are intercalated with thick lenticular units of pillowed lava. As in the Labrador Trough, basin filling was cyclical but appears to be in the reverse order. Geology. Belcher Islands are located in southeastern Hudson Bay, 100 km west of Grande Rivière de la Baleine, Québec.The total land mass of about 13 000 km 2 is composed of a group of long, narrow islands, lying northeast/southwest along a very extensive coastline. GEOLOGICAL FORMATIONS The islands are made up of a thick series of interbedded igneous rocks and sediments. The exposed clastic sedimentary rocks, as well as volcanic and carbonate units record rifting and subsidence of the Superior craton during this period. It is coeval with a series of mid-Paleoproterozoic packages circumferencing nearly the entirety of the craton (clockwise they are the Belcher Group, Cape Smith Belt, Administratively, they belong to the Qikiqtaaluk Region of the territory of Nunavut, Canada. [13], "Morton's Musings: When 'God' and 'Satan' battled in a barren land; the Belcher Islands Murders", "Demographic characteristics of circumpolar caribou populations: ecotypes, ecological constraints/releases, and population dynamics", https://en.wikipedia.org/w/index.php?title=Belcher_Islands&oldid=989005949, Archipelagoes of the Canadian Arctic Archipelago, Hudson's Bay Company trading posts in Nunavut, Former populated places in the Qikiqtaaluk Region, Islands of the Canadian Arctic Archipelago, Wikipedia articles with WorldCat-VIAF identifiers, Creative Commons Attribution-ShareAlike License, Born, David O. Figure 10.2 Representative Drill Section for 2011 Program. Figure 7.3 Stratigraphic Column of the Belcher Islands. And Belcher Islands, near the geometrical center, may be the aqueously-differentiated trans-Neptunian object (TNO) core of the icy body from a much earlier Proterozoic perturbation of the former binary TNO pair which spiraled in to merge and melt a salt-water ocean in the merged ‘contact binary’. There are two main volcanic sequences on the Belcher Islands called the Eskimo and overlying Flaherty volcanics. The rocks are found in-place (where they originally formed) today only in the Belcher Islands in southeastern Hudson Bay, so it is possible that the Lake Sakakawea omars originated in the Belcher Islands, or near there. Age of the Upper Volcanics, Belcher Islands The sedimentary and volcanic rocks of the Belcher Islands re-present part of an embayed miogeosynclinal sequence of the Circum-Ungava Geosyncline (Dimroth et al. 20 . South-plunging anticlines along the east side of Belcher Islands, Hudson Bay. Source: Wikipedia. Landing on the shores of Belcher Islands (Hudson Bay) was also something of a mind warp; from a country that straddles a plate boundary, has a volcanic rift zone in central North Island, and faces a subduction zone within a stone’s throw of the east coast, to a part of the Canadian Shield where not much has happened over the last two billion years. 33 . [8] Age of the Upper Volcanics, Belcher Islands The sedimentary and volcanic rocks of the Belcher Islands re-present part of an embayed miogeosynclinal sequence of the Circum-Ungava Geosyncline (Dimroth et al. There are no trees. Figure 10.1 Drill Plan for 2011 Program 29 . The Middle Precambrian Flaherty Formation consists of a thick sequence of volcanic rocks of both effusive and explosive origin, derived from a source area west of the Belcher Islands. Chapters: Belcher Islands. The Belcher Islands are especially interesting due to their unique geological features, the local wildlife, and the many stories surrounding its people – including a mysterious mass … The geologic units of the Belcher Islands are Proterozoic. Photo by A.K. Social Science Notes - 1, Northern Science Research Group, Department of Indian Affairs and Northern Development, Ottawa, January 15, 1970. Several species of willow (Salix) form a large component of the native small shrubbery on the archipelago. As in the Labrador Trough, basin filling was cyclical but appears to be in the reverse order. "Eskimo Education and the Trauma of Social Change". [2006] 744; [2011] 812), which has an airstrip. It was at this juncture that Nero, my 4 Dr. Leith, who is a well-known authority on the geology of northern Minnesota and Michigan, made There is also a wide variety of fish that can be caught such as Arctic char, cod, capelin, lump fish, and sculpin. Since the original publication of the Death Valley regional groundwater flow system (DVRFS) numerical model in 2004, more information on the regional groundwater flow system in the form of new data and interpretations has been compiled. Figure 12.1 Regression Plot of Fe2O3 between ALS Chemex and SGS. 1970). These unusual low-lying islands extend over about 13,000 square kilometers (5000 square miles) but have a land area of only about 2800 square kilometers (1080 square miles). The flows were accompanied by intrusion of the Haig diabase-gabbro sills and a few dykes in all of the underlying formations and are not known to be present in the uppermost part of the Flaherty Formation. The islands are skinny, separated by narrow, frequently stormy inlets. The bedrock that comprises the shoreline and landscape that lies inland of the Nastapoka arc largely consists of Archean age rocks of the Superior craton. The geologic units of the Belcher Islands are Proterozoic. Mr. Barber has worked in exploration and mining for over 30 years, including extensive experience in greenstone-hosted gold deposits, both narrow vein and bulk tonnage, as well as epithermal gold deposits, porphyry copper-gold, VMS base metal, … To find evidence of this even, researchers turned to barite from the Belcher Islands in Hudson Bay, Canada. It’s rather like the Valley and Ridge province of the eastern United States, except that the Canadian example is much improved by being flooded with sea water. [11][12], In 1998, the Belcher Island caribou (Rangifer tarandus groenlandicus) herd numbered 800. 29 (1981), No. 20 . The Belcher Islands In the heart of Hudson Bay, the Belcher Islands are an archipelago made up of more than 1,500 islands spread out over an area of more than 13,000 square kilometers. A Submarine Fan - Distal Molasse Sequence of Middle Precambrian Age, Belcher Islands… Paleoproterozoic, Belcher Islands. Before 1914, English-speaking cartographers knew very little about the Belcher Islands, which they showed on maps as specks, much smaller than their true extent. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. The hamlet of Sanikiluaq is on the north coast of Flaherty Island. The Laurentide Ice Sheet eroded omars from the Belcher Islands, an archipelago limited to only about a quarter of 1% of Hudson Bay. Flame structures are commonly associated with load casts. glauca. The exposed clastic sedimentary rocks, as well as volcanic and carbonate units record rifting and subsidence of the Superior craton during this period. The islands, low-lying and striated, cover a total area of about 5,000 square miles (13,000 square km), of which 1,118 square miles (2,896 square km) is land. the geological elements required for future prospecting of similar carving stone resources. REPORTS ABOUT THE BELCHER ISLANDS The examination of Taylor and Gillies Islands completed (the ore deposits were found to be of no present economic interest), I prepared to return to the railway frontier. New Glasgow and Belcher Islands Eskimoes, 16 mm, 1920’s Depostor Therrien Coll., Number NFA 76-9-25; deposited Jan 1975 Sanford, B.V.; Operation Winisk, may have reference to WWII and Belcher; 1969 (December), Pages 561-582. Hodgskiss1 and E.A. What are the islands of the Maldives made of? The hamlet of Sanikiluaq (where the majority of the archipelago's inhabitants live) is on the north coast of Flaherty Island and is the southernmost in Nunavut. Instead, the group turned to barite, a mineral collected from the Belcher Islands in Hudson Bay, Canada, that encapsulates a record of oxygen in the atmosphere. Subvertical, wrinkled conduits, 2-3 mm wide, are dewatering pillars formed by escaping fluids during early compaction. Perhaps that’s a bit of an exaggeration, but this prolonged … These evaporites were deposited by brines in very shallow pools such as those encountered today in the Persian Gulf.…. The islands, low-lying and striated, cover a total area of about 5,000 square miles (13,000 square km), of which 1,118 square miles (2,896 square km) is land. In areal distribution, these rocks consist of about 60% Archean granitic plutons and granitic gneiss. Belcher Islands, archipelago in southeastern Hudson Bay, north of the mouth of James Bay, Baffin region, Nunavut territory, Canada. Proterozoic, Belcher Islands. Pages: 164.
