The Caledonide Orogen in the Nordic countries is exposed Norway, western Sweden, westernmost Finland, on Svalbard and northeast Greenland. In mountains of Scandinavia, structure dominated by E-vergent thrusts with allochthons derived from Baltoscandian platform margin, outboard oceanic (Iapetus) terranes highest thrust sheets having Laurentian affinities. other side this bivergent orogen well northeastern Greenland, where W-vergent emplace continental margin assemblages onto platform....

Abstract Near the Barents Sea coast in northern Timan, turbidites of probable Neoproterozoic age are intruded by pre-tectonic dolerites and a major suite gabbros, granites syenites (some nepheline bearing). Zircon ion microprobe dating three plutons has yielded well-defined ages 613–617 Ma. This alkaline igneous activity apparently represents final phase Vendian extensional magmatism prior to Timanian Orogeny. Previous work on late post-orogenic calc-alkaline basement beneath Pechora Basin,...

Agriculture is inherently multifunctional. It jointly produces more than food, fibre or oil, having a profound impact on many elements of economies and ecosystems. A comprehensive framework used to present new data annual external costs in Germany ( 1.2 billion; US$2 billion), the UK 2.3 US$3.8 billion) USA 21 US$34.7 billion). These are equivalent 49-208/ha (US$81-343/ha) arable grassland. also positive externalities, though there no valuation framework, public benefits appear be range...

The recent discovery of ultrahigh-pressure (UHP) mineral parageneses in the far-transported (greater than 400 km) Seve Nappe Complex Swedish Caledonides sheds new light on subduction system that dominated contracting Baltoscandian margin continental Baltica during Ordovician and culminated collision with Laurentia Silurian to Early Devonian. High-grade metamorphism this Neoproterozoic Cambrian rifted, extended, dike-intruded outer-margin assemblage started may have continued, perhaps...

Abstract Catastrophic failure of a tailings dam at an iron ore mine complex in Brumadinho, Brazil, on 25th January 2019 released 11.7 million m 3 downstream. Although reportedly monitored using array geotechnical techniques, the collapse occurred without any apparent warning. It claimed more than 200 lives and caused considerable environmental damage. Here we present Intermittent Small Baseline Subset (ISBAS) technique satellite-based interferometric synthetic aperture radar (InSAR) data to...

A new regional compilation map and U-Pb ages on a suite of variably deformed, Ordovician, calc-alkaline intrusive igneous rocks requires reinterpretation the nature continental collision extensional exhumation deep-seated Western Gneiss Region west northwest Trondheim. plutonic rocks, in age range 482 to 438 Ma, previously known from region Smøla-Hitra-Ørlandet-Froan above Høybakken detachment fault associated with Devonian 'Old Red Sandstone' basins, is shown extend over wide areas below...

This volume was conceived during EUROPROBE’s investigations into the dynamic evolution of Palaeozoic Uralide Orogen and relationships northwards Eurasian high Arctic. During these European Science Foundation studies, preservation Neoproterozoic deformation over large regions northern Europe became increasingly apparent. mainly Vendian tectonic event is referred to as Timanian Orogeny focus many recent on-going investigations. Much progress has been made in understanding a Memoir synthesizing...

The COSC project is focused on the mid Paleozoic Caledonide Orogen in Scandinavia order to better understand orogenic processes, both past and today's active mountain belts. It relates two of ICDP's main themes – fundamental physics plate tectonics heat, mass fluid transfer through Earth's crust, improving interpretation geophysical data used determine structure properties crust. Lateral transport Caledonian allochthons over distances several hundreds kilometers Scandes, by a combination...

Abstract Throughout the high Arctic, from northern Canada (Pearya) to eastern Greenland, Svalbard, Franz Josef Land, Novaya Zemlya, Taimyr and Severnaya Zemlya and, at lower Arctic latitudes, in Urals Scandinavian Caledonides, there is evidence of Grenville–Sveconorwegian Orogen. The latest orogenic phase ( c . 950 Ma) well exposed but only minor Mesoproterozoic fragments this orogen occur on land. However, detrital zircons Neoproterozoic Palaeozoic successions provide unambiguous earliest...

In this paper, we investigate land motion and groundwater level change phenomena using differential interferometric synthetic aperture radar (DInSAR) over the Northumberland Durham coalfield in United Kingdom. The study re-visits earlier research that applied a persistent scatterers interferometry (PSI) technique to ERS (European Remote Sensing) ENVISAT (Environmental Satellite) data. Here, Intermittent Small Baseline Subset (ISBAS) DInSAR is ERS, Sentinel-1 SAR datasets covering late 1990s,...

Abstract Metamorphic diamond in crustal rocks provides important information on the deep subduction of continental crust. Here, we present a new occurrence within Seve Nappe Complex (SNC) Scandinavian Caledonides, Åreskutan Jämtland County, Sweden. Microdiamond is found situ as single and composite (diamond+carbonate) inclusions garnet, kyanite‐bearing paragneisses. The preserve primary peak pressure assemblage Ca,Mg‐rich garnet+phengite+kyanite+rutile, with polycrystalline quartz surrounded...

Permafrost thaw resulting from climate warming is threatening to release carbon high latitude peatlands. The aim of this research was determine subsidence rates linked permafrost in sub-Arctic peatlands Sweden using historical orthophotographic (orthophotos), Unoccupied Aerial Vehicle (UAV), and Interferometric Synthetic Aperture Radar (InSAR) data. orthophotos showed that the palsa on study sites have been contracting their areal extent, with greatest loss between 2002 2008. surface motion...
