Re-Evaluation of Strike-Slip Displacements Along and Bordering Nares Strait
Polarforschung 74 (1-3), 129 – 160, 2004 (erschienen 2006) In Search of the Wegener Fault: Re-Evaluation of Strike-Slip Displacements Along and Bordering Nares Strait by J.

Especially convincing is evidence, presented by DAMASKE & OAKEY (2006), that at least one basic dyke of Neoproterozoic age extends across Smith Sound from Inglefield Land to inshore eastern Ellesmere Island without any recognizable strike slip offset. INTRODUCTION These results confirm that no major sinistral fault exists in southern Nares Strait. It is apparent to both earth scientists and the general public To account for the absence of a Wegener Fault in most parts of Nares Strait, that the shape of both coastlines and continental margins of the present paper would locate the late Paleocene-Eocene Greenland plate boundary on an interconnected system of faults that are 1) traced through western Greenland and eastern Arctic Canada provide for a Jones Sound in the south, 2) lie between the Eurekan Orogen and the Precam- satisfactory restoration of the opposing lands. -

Haughton Astrobleme: a Mid-Cenozoic Impact Crater Devon Island, Canadian Arctic Archipelago
Haughton Astrobleme: A Mid-Cenozoic Impact Crater Devon Island, Canadian Arctic Archipelago T. FRISCH’ and R. THORSTEINSSON’ ABSTRACT. Haughton Astrobleme is a nearly circular impact crater with a diameter of about 16km and a central uplift in Devon Island. Bedrock exposed in the crater comprised the followingmainly carbonate Lower Ordovician to, Upper Silurian formations in order upward: Eleanor River, Bay Fiord, Thumb Mountain, Irene Bay and Allen Bay. The Eleanor River Formation in the centre of the crater is raised about 480 m above its normal stratigraphic position outside the crater. The much shattered and faulted lower Paleozoic rocks within thecrater contrast markedly with the subhorizontal surrounding strata.The AllenBay Formation constitutes surface exposure around all but the easternmost part of the crater’s border where the Thumb Mountain and Irene Bay Formations are exposed. Also exposed in the crater are two newly recognized, and as yet unnamed, formations: a polymict impact breccia that overlies the lower Paleozoic rocks, with marked angular unconformity and crops out over about a quarter of the area of the crater; and a unit of lake sediments near the western border of the crater that lies disconformably on the impact breccia and with angular’unconformity on the lower Paleozoic rocks. The impact breccia is composed chiefly of carbonate rocks, but locally contains clasts of Precambrian crystalline basement from a depth estimated to be at least 1700 m. The basement clasts show varying degrees of shock metamorphism, the highest being that displayed by rocks with vesicular, flow-banded feldspar or quartz glass. Coesite has been identified in a sample of gneiss. -

The Last Glaciation of East-Central Ellesmere Island, Nunavut: Ice Dynamics, Deglacial Chronology, and Sea Level Change1
1355 The last glaciation of east-central Ellesmere Island, Nunavut: ice dynamics, deglacial chronology, and sea level change1 John England, I. Rod Smith, and David J.A. Evans Abstract: During the last glacial maximum of east-central Ellesmere Island, trunk glaciers inundated the landscape, en- tering the Smith Sound Ice Stream. Accelerator mass spectrometry (AMS) dates on individual shell fragments in till in- dicate that the ice advanced after 19 ka BP. The geomorphic and sedimentary signatures left by the trunk glaciers indicate that the glaciers were polythermal. The configuration and chronology of this ice is relevant to the reconstruc- tion of ice core records from northwestern Greenland, the history of iceberg rafting of clastic sediments to northern Baffin Bay, the reopening of the seaway between the Arctic Ocean and Baffin Bay, and the regional variability of arc- tic paleoenvironments. Deglaciation began with the separation of Ellesmere Island and Greenland ice at fiord mouths ~8–8.5 ka BP. Ice reached fiord heads between 6.5 and 4.4 ka BP. Trunk glacier retreat from the fiords of east-central Ellesmere Island occurred up to 3000 years later than in west coast fiords. This later retreat was favoured by (1) im- poundment by the Smith Sound Ice Stream in Kane Basin until ~8.5 ka BP, which moderated the impact of high sum- mer melt recorded in nearby ice cores between ~11.5 and 8.5 ka BP; (2) the shallow bathymetry and narrowness (<2 km) of the east coast fiords, which lowered calving rates following separation of Innuitian and Greenland ice; and (3) the likelihood of higher precipitation along east Ellesmere Island. -
Anhydrite-Carbonate Cycles of the Ordovician
ANHYDRITE-CARBONATE CYCLES OF THE ORDOVICIAN BAUMANN FIORD FORMATION, ELLESMERE ISLAND, ARCTIC CANADA: A GEOLOGICAL HISTORY by Grant Dilworth Mossop, B.Sc.(Hons.), M.Sc. Thesis submitted for the degree of Doctor of Philosophy of the University of London Geology Department, Imperial College of Science and Technology, London, England. November, 1973. A 11 ABSTRACT The Baumann Fiord Formation of central Elle'.-lmere Island is made up of between 700 and 1,500 feet of concordantly compounded carbonate — anhydrite cycles. The cycles, which average 12 feet in thickness, characteristically comprse a basal shallow—marine lime mudstone facies, followed upwards by an intertidal facies with algal stromatolites, in turn overlain by a supratidal anhy- drite facies, the ~•mole bounded top and bottom by erosion surfaces. Each of these regressive sequences is representative of a discrete sabkha sedimentation cycle and the formation as a whole was built up through repetitous superimposition of successive sabkha cycles. Much of the Baumann Fiord anhydrite underwent early—stage compactional flow, producing layered and laminar anhydrite. Deep burial, accompanied by pervasive recrystallization, further modified the textural character of some of the anhydrite, notably that of the seaward portion of the sedimentary wedge. The Ellesmerian Orogeny (Middle Devonian to Early Mississippian) brought folding and, where deformation was excessive, it caused remobilization and flow of the anhydrite. Subsequent thrust— faulting (Tertiary Eurekan Orogeny) produced shear zones at various levels within the formation. During exhumation the basal reaches of the formation locally underwent hydraulic fracturing. Water from the underlying stratamoved up into the evaporites and hydrated the anhydrite to form secondary gypsum. -

Fig. 1. Sketch map of parts of Ellesmere and Axel Heiberg islands. I GEOLOGICAL INVESTIGATIONS IN ELLESMERE AND AXEL HEIBERG ISLANDS, 1956* R. Thorsteinsson and E. T. Tozert URING the past six years members of the Geological Survey of Canada have been investigatingthe geology of theQueen Eiizabeth Islands. PartiesD have worked from the weather stations at Resolute (Thorsteinsson and Fortier, 1954; Thorsteinsson, 19-55>,Isachsen (Heywood, 1954), Alert (Black- adar, 1954) and Mould Bay (Tozer, 1956). R. L. Christie (1955) represented the Survey on the1954 Northern Ellesmere Expedition of the Defence Research Board(Hattersley-Smith et al., 1955). In 1955, withthe aidof helicopters, the members of “Operation Franklin”, a Geological Survey project directed by Y. 0. Fortier, studied the geology of many parts of the country too far from the weather stations to be readily accessible. At the beginning of 1956, the surroundings of only one weather station in theislands, Eureka on the west coast of Ellesmere Island, had not been systematically explored by the Geo- logical Survey. From the studies of Per Schei (in Sverdrup, 1904) and J. C. Troelsen (1950, 1952) it was known to be an area of considerable interest, and this conclusion was confirmed by an examination of air photographs. Conse- quently, the writers undertook an exploration of this area for the Geological Survey between April and September 1956. The useof theEureka Weather Station as a base was made possible throughcourtesy of the Meteorological Division, Air Services, Department of Transport. We wish to express our gratitude to the Director of the Divi- sion,Dr. AndrewThompson, and also tothe Canadian and UnitedStates personnel atEureka for theirhospitality and assistance. -
Finding the Cook Case's Smoking Gun at Last
2017 December DIO 21 47 z4 Finding the Smoking Gun The LongOverlooked Central Document Recovered by Robert M. Bryce A Three intriguing books A1 Almost no story stands in isolation. This story begins with another, that of the eccentric Arctic explorer, Charles Francis Hall. A2 In 1971, I was in the U.S. Army and home for Christmas at my parents' house in Mt.Dora, Florida. My father had long been a reader of books about exploration and mountain climbing. Perhaps that's why my sister gave him a book that she had found on the remainder rack in a Chicago bookstore. It was the first biography of Hall, Weird and Tragic Shores, by Chauncy Loomis (NY, Knopf, 1971). It was the title that got me to pick it up, and the back of the dust jacket that showed Hall's disinterred body, its ghostly face staring from under a foldedback American flag with which he had been covered before his coffin was placed into the Greenland permafrost in 1871, nearly a century before, that got me to look inside. Though my father had vicariously accompanied most of the famous expeditions up Annapurna or Everest and suffered through many harrowing and failed attempts in the Arctic or Antarctic to reach their poles, I had never read any book on these topics. After reading Loomis's book, that all changed. The mysterious demise of Hall at the farthest place ever reached by a ship up to then on the desolate, barren coast of northwest Greenland left me strangely disturbed and set me to reading other stories of obsession and hardship on the icy fringes of the earth. -
