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. -

Part 629 – Glossary of Landform and Geologic Terms
Title 430 – National Soil Survey Handbook Part 629 – Glossary of Landform and Geologic Terms Subpart A – General Information 629.0 Definition and Purpose This glossary provides the NCSS soil survey program, soil scientists, and natural resource specialists with landform, geologic, and related terms and their definitions to— (1) Improve soil landscape description with a standard, single source landform and geologic glossary. (2) Enhance geomorphic content and clarity of soil map unit descriptions by use of accurate, defined terms. (3) Establish consistent geomorphic term usage in soil science and the National Cooperative Soil Survey (NCSS). (4) Provide standard geomorphic definitions for databases and soil survey technical publications. (5) Train soil scientists and related professionals in soils as landscape and geomorphic entities. 629.1 Responsibilities This glossary serves as the official NCSS reference for landform, geologic, and related terms. The staff of the National Soil Survey Center, located in Lincoln, NE, is responsible for maintaining and updating this glossary. Soil Science Division staff and NCSS participants are encouraged to propose additions and changes to the glossary for use in pedon descriptions, soil map unit descriptions, and soil survey publications. The Glossary of Geology (GG, 2005) serves as a major source for many glossary terms. The American Geologic Institute (AGI) granted the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service) permission (in letters dated September 11, 1985, and September 22, 1993) to use existing definitions. Sources of, and modifications to, original definitions are explained immediately below. 629.2 Definitions A. Reference Codes Sources from which definitions were taken, whole or in part, are identified by a code (e.g., GG) following each definition. -

The Superior Craton is a large piece of Earth’s within the past 15 years. Most of these kimberlites occur as crust that has been tectonically stable for over 2.5 billion years. clusters within the Canadian provinces of Ontario and Quebec The long duration of tectonic stability has allowed the underlying (figs. 1 and 2). Moorhead et al. (2000) noted that the average mantle to cool enough to develop the necessary temperature and distance between kimberlite fields/clusters across the Canadian pressure conditions to form diamonds at depths of more than 50 Shield is similar to the typical global average distance of 250 miles miles below the surface. Diamonds are transported to the surface (400 km) between large kimberlite fields. Globally, only 14% through kimberlitic eruptions, which are volcanic eruptions that of kimberlites are diamondiferous (contain diamonds), most in originate tens of miles below the surface and typically erupt concentrations too low for commercial mining. The percentage along zones of weakness in Earth’s crust such as faults and of diamondiferous Superior kimberlites appears to be higher than fractures. The resulting eruption commonly forms a pipe-shaped the global average, including 1) the Attawapiskat cluster – 16 of 18 geologic feature called a kimberlite. Kimberlites typically occur kimberlites (89%) are diamondiferous and so far one kimberlite in groups referred to as either fields or clusters. -

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. -

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.

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.

[1] When the mantle melts, it produces ultramafic magma if the site of melting is unusually deep, the degree of melting is unusually high, or the source is refractory. For such melting to happen, the source must be unusually hot or very rich in volatiles. Differing conditions produce a spectrum of ultramafic magma types. Komatiites form by high degrees of melting, at great depths, of an essentially anhydrous source. Barberton- type komatiites are moderately high degree melts from a particularly hot and deep source; Munro-type komatiites are very high degree melts of a slightly cooler source. -
