    Detrital zircon ages and provenance of the Upper Paleozoic successions of Kotel’ny Island (New Siberian Islands archipelago) Victoria B. Ershova1,*, Andrei V. Prokopiev2, Andrei K. Khudoley1, Nikolay N. Sobolev3, and Eugeny O. Petrov3 1INSTITUTE OF EARTH SCIENCE, ST. PETERSBURG STATE UNIVERSITY, UNIVERSITETSKAYA NAB. 7/9, ST. PETERSBURG 199034, RUSSIA 2DIAMOND AND PRECIOUS METAL GEOLOGY INSTITUTE, SIBERIAN BRANCH, RUSSIAN ACADEMY OF SCIENCES, LENIN PROSPECT 39, YAKUTSK 677980, RUSSIA 3RUSSIAN GEOLOGICAL RESEARCH INSTITUTE (VSEGEI), SREDNIY PROSPECT 74, ST. PETERSBURG 199106, RUSSIA ABSTRACT Plate-tectonic models for the Paleozoic evolution of the Arctic are numerous and diverse. Our detrital zircon provenance study of Upper Paleozoic sandstones from Kotel’ny Island (New Siberian Island archipelago) provides new data on the provenance of clastic sediments and crustal affinity of the New Siberian Islands. Upper Devonian–Lower Carboniferous deposits yield detrital zircon populations that are consistent with the age of magmatic and metamorphic rocks within the Grenvillian-Sveconorwegian, Timanian, and Caledonian orogenic belts, but not with the Siberian craton. The Kolmogorov-Smirnov test reveals a strong similarity between detrital zircon populations within Devonian–Permian clastics of the New Siberian Islands, Wrangel Island (and possibly Chukotka), and the Severnaya Zemlya Archipelago. These results suggest that the New Siberian Islands, along with Wrangel Island and the Severnaya Zemlya Archipelago, were located along the northern margin of Laurentia-Baltica in the Late Devonian–Mississippian and possibly made up a single tectonic block. Detrital zircon populations from the Permian clastics record a dramatic shift to a Uralian provenance. The data and results presented here provide vital information to aid Paleozoic tectonic reconstructions of the Arctic region prior to opening of the Mesozoic oceanic basins.

    GY 112 Lecture Notes D. Haywick (2006) 1 GY 112 Lecture Notes Archean Geology Lecture Goals: A) Time frame (the Archean and earlier) B) Rocks and tectonic elements (shield/platform/craton) C) Tectonics and paleogeography Textbook reference: Levin 7th edition (2003), Chapter 6; Levin 8th edition (2006), Chapter 8 A) Time frame Up until comparatively recently (start of the 20th century), most geologists focused their discussion of geological time on two eons; the “Precambrian” and the Phanerozoic. We now officially recognize 4 eons and the Precambrian is just used as a come-all term for all time before the Phanerozoic: Eon Time Phanerozoic 550 MA to 0 MA Proterozoic 2.5 GA to 550 MA Archean 3.96 GA to 2.5 GA Hadean 4.6 GA to 3.96 GA The “youngest” of these two new eons, the Archean, was first introduced by field geologists working in areas where very old rocks cropped out. One of these geologists was Sir William Logan (pictured at left; ess.nrcan.gc.ca ) one of the most respected geologists working with the Geological Survey of Canada. His study area was the Canadian Shield. Logan was able to identify two major types of rocks; 1) layered sedimentary and volcanic rocks and 2) highly metamorphosed granitic gneisses (see image at the top of the next page from http://www.trailcanada.com/images/canadian-shield.jpg). Logan found evidence that the gneisses mostly underlayed the layered rocks and hence, they had to be older than the layered rocks. The layered rocks were known to be Proterozoic in age.

Received 2020 November 6; in original form 2020 February 27 SUMMARY We use the recently deployed ScanArray network of broad-band stations covering most of Norway and Sweden as well as parts of Finland to analyse the propagation of Rayleigh waves in Scandinavia. Applying an array beamforming technique to teleseismic records from ScanArray and permanent stations in the study region, in total 159 stations with a typical station distance of about 70 km, we obtain phase velocities for three subregions, which collectively cover most of Scandinavia (excluding southern Norway). The average phase dispersion curves are similar for all three subregions.

Geological Survey, Denver, Colorado Page 1 of 16 South and North Barents Triassic-Jurassic Total Petroleum System of the Russian Offshore Arctic2 Sandra J. Lindquist, Consulting Geologist Contractor to the U.S. Geological Survey, Denver, CO October, 1999 FOREWORD This report was prepared as part of the World Energy Project of the U.S. Geological Survey. In the project, the world was divided into 8 regions and 937 geologic provinces. The provinces have been ranked according to the discovered oil and gas volumes within each (Klett and others, 1997). Then, 76 "priority" provinces (exclusive of the U.S. and chosen for their high ranking) and 26 "boutique" provinces (exclusive of the U.S. and chosen for their anticipated petroleum richness or special regional economic importance) were selected for appraisal of oil and gas resources. The petroleum geology of these priority and boutique provinces is described in this series of reports. A detailed report containing the assessment results will be available separately, if such results are not reported herein. The priority South Barents Basin Province ranks 35th in the world, exclusive of the U.S.

(Asha Group) of Ediacaran-Middle Cambrian(?) age along with the results obtained from the Early Devonian Takaty Fm. are presented. The age of the Asha Group is traditionally labeled as Upper Vendian in the Russian stratigraphic chart that overlaps with the Ediacaran in the International stratigraphic chart. The dZr whose ages fall within the age-interval of (500-750 Ma) are common in the Basu and Kukkarauk Fm. These ages are typical for crystalline complexes in the Pre- Uralides-Timanides orogen. The identification of zircons with this age range agrees with commonly adopted interpretations for the depositional origin of the Asha Group as a molasse resulting from the erosion of that orogenic belt. Based on the estimates of the youngest ages of dZr along with the tentative identification of inarticulate brachiopods in the Kukkarauk Fm., it appears that the upper part of the Asha Group may extend into the Middle Cambrian.

  • Rutile Mineral Chemistry and Zr-In-Rutile Thermometry In
    minerals Article Rutile Mineral Chemistry and Zr-in-Rutile Thermometry in Provenance Study of Albian (Uppermost Lower Cretaceous) Terrigenous Quartz Sands and Sandstones in Southern Extra-Carpathian Poland Jakub Kotowski * , Krzysztof Nejbert and Danuta Olszewska-Nejbert Faculty of Geology, University of Warsaw, Zwirki˙ i Wigury 93, 02-089 Warszawa, Poland; [email protected] (K.N.); [email protected] (D.O.-N.) * Correspondence: [email protected] Abstract: The geochemistry of detrital rutile grains, which are extremely resistant to weathering, was used in a provenance study of the transgressive Albian quartz sands in the southern part of extra-Carpathian Poland. Rutile grains were sampled from eight outcrops and four boreholes located on the Miechów, Szydłowiec, and Puławy Segments. The crystallization temperatures of the rutile grains, calculated using a Zr-in-rutile geothermometer, allowed for the division of the study area into three parts: western, central, and eastern. The western group of samples, located in the Citation: Kotowski, J.; Nejbert, K.; Miechów Segment, is characterized by a polymodal distribution of rutile crystallization temperatures ◦ ◦ ◦ Olszewska-Nejbert, D. Rutile Mineral (700–800 C; 550–600 C, and c. 900 C) with a significant predominance of high-temperature forms, Chemistry and Zr-in-Rutile and with a clear prevalence of metapelitic over metamafic rutile. The eastern group of samples, Thermometry in Provenance Study of corresponding to the Lublin Area, is monomodal and their crystallization temperatures peak at Albian (Uppermost Lower 550–600 ◦C. The contents of metapelitic to metamafic rutile in the study area are comparable. The Cretaceous) Terrigenous Quartz central group of rutile samples with bimodal distribution (550–600 ◦C and 850–950 ◦C) most likely Sands and Sandstones in Southern represents a mixing zone, with a visible influence from the western and, to a lesser extent, the eastern Extra-Carpathian Poland.
