    Geology, petrology and alteration geochemistry of the Palaeoproterozoic intrusive hosted Ägträsk Au deposit, Northern Sweden2011Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, nr 350, s. 105-132Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Ägträsk intrusive hosted Au deposit, Skellefte district, northern Sweden, is situated in the oldest, most heterogeneous part of the c. 1.89-1.86 Ga Jörn granitoid complex, which intruded a complex volcano-sedimentary succession in an island arc or continental margin arc environment. The Tallberg porphyry Cu deposit, situated only 3 km west of Ägträsk, is associated with quartz feldspar porphyritic dykes. These dykes are suggested to be genetically related to similar porphyry dykes in Älgträsk and the tonalitic host rock in Tallberg. The granodiorite hosting the Ägträsk Au-deposit does not appear to be genetically related to the tonalite or the porphyry dykes.

    The uncertainty cascade in model fusion2017Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 408, nr 1, s. 255-266Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There are increasing demands in assessing the impacts of change on environmental systems to couple different model components together in a cascade, the outputs from one component providing the inputs to another with or without feedbacks in the coupling. Each model component will necessarily involve some uncertainty in its specification and simulations that can be conditioned using some observational data. Taking account of this uncertainty should result in more robust decision making and may change the nature of the decision made. The difficulty in environmental decision making is in making proper estimates of uncertainties when so many of the sources of uncertainty result from lack of knowledge (epistemic uncertainties) rather than uncertainty that can be treated as random variability (aleatory uncertainty). This is particularly the case for problems that involve cascades of model components. Examples are the use of UKCP09 climate scenarios in impact studies, flood risk assessment involving models of runoff generation and their impact on hydraulic models of flood plains, and integrated catchment management involving upstream to downstream surface and subsurface routing of water quality variables. The uncertainties are such that, even for relatively simple problems, they can result in wide ranges of potential outputs. This poses the questions that will be considered in this paper: how to take account of knowledge uncertainties in cascades of model components; and how to constrain the potential uncertainties for use in making decisions. In particular we highlight the difficulties of defining statistical likelihood functions that properly reflect the non-stationary uncertainty characteristics expected of epistemic sources of uncertainty.

    Late Ordovician molluscs of the central and eastern Anti-Atlas, Morocco2019Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 485Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    More than 30 species of tergomyan, gastropod, bivalve and cephalopod molluscs are described fromthe Late Ordovician of central and eastern Anti-Atlas, Morocco. For the cephalopods this represents the firstsystematically known taxa of the region. Tergomyans and gastropods are most common in the more shalypart of the Lower Ktaoua Formation, while bivalves are more frequent in the sandy part of the Lower Second Bani Formation. A southern Gondwana aspect is evident for the tergomyan, gastropod and bivalve assemblages,sharing many taxa with Bohemia, while no clear signal is present for the cephalopods. The latter reflects insufficientknowledge of the fauna of large parts of these areas. The widely recognized Holopea? antiquata is transferredto the genus Radvanospira gen. nov.; other new gastropod taxa include Allossospira gen. nov.,Tritonophon grandis sp. nov., Radvanospira baniensis sp. nov. and Lophospira latilabra sp. nov. Most ofthe diverse bivalve fauna and the few cephalopods are left in open nomenclature but new taxa include thebivalve Praenucula pojetai sp. nov. and the cephalopods Wadema tattai sp. nov. and Tafadnatoceras tiouririnensegen. et. sp. nov. The Late Ordovician bivalves from Morocco are dominated by pteriomorphs andprotobranchs, inhabiting infaunal, semi-infaunal and epifaunal niches.

    Pressure–temperature evolution of a kyanite–garnet pelitic gneiss from Åreskutan: evidence of ultra-high-pressure metamorphism of the Seve Nappe Complex, west-central Jämtland, Swedish Caledonides2014Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 390, s. 321-336Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    New evidence is presented for ultra-high-pressure metamorphism of kyanite–garnet pelitic gneiss in the Åreskutan Nappe of the Seve Nappe Complex, in the central part of the Scandinavian Caledonides. Modelled phase equilibria for a peak pressure assemblage garnet + phengite + kyanite + quartz (coesite) in the NCKFMMnASH system record pressure and temperature conditions of c. 26–32 kbar at 700–720 °C, possibly up to ultra-high-pressure conditions. Subsequent decompression, simultaneous with an increase of temperature to c. 800–820 °C, led to partial melting largely owing to the dehydration and breakdown of phengite. Based on existing isotope age data, we conclude that the Middle Seve Nappe in central Jämtland experienced deep subduction in the late(st) Ordovician, prior to decompression and partial melting of the pelitic protoliths during Early Silurian extrusion, giving way in the Mid to Late Silurian to thrusting on to the Baltoscandian platform. Nappe emplacement probably continued into and through the Early Devonian.

    Salt flow by aggrading and prograding overburdens1996Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 100, s. 243-258Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The mechanisms responsible for segmentation of salt sheets and their emplacement into higher stratigraphic levels are not separable and act simultaneously. Three sets of centrifuge models with strongly planar anisotropic (anisotropy, δ, the ratio between the effective viscosities in pure and simple shear, ranging between 4.8 and 16.4) microlaminate overburdens are used to study the effect of aggradation and progradation on segmentation and emplacement of allochthonous salt sheets.

    In the first set of models, a tabular buoyant source layer was overlain by tabular anisotropic overburden simulating aggradation. During centrifuging, the underlying ductile source layer was segmented into individual wall-like diapirs by the subsiding blocks formed due to extension and faulting of the overburden. The extensional zone in these models started at the spreading edge (free face) of the model and migrated backwards.

    In the second set of models, a tabular buoyant source layer was overlain successively by wedges of anisotropic overburdens simulating progradation. During centrifuging, the buoyant layer was displaced from the back of the model, where loading was higher, towards the free face in the front of the model, where overburden units were thinner. Overburden units extended at the back and the middle of the model while contractional structures dominated at the front, where asymmetric diapirs formed overhangs that spread ‘basinward’ to form ‘salt’ sheets.

    In the third set of models, a wedge-shaped buoyant source layer was overlain successively by wedges of anisotropic overburden simulating progradation. The overburden wedge created a lateral pressure gradient ranging from 144 Pa at the back of the model to 80 Pa at the front when deformed in the centrifuge. In these models, as in the second set of models, the underlying buoyant mass was displaced ‘basinward’ by the subsiding thicker overburden units at the back of the model. Contractional structures dominated the deformation at the leading edge of the wedge.

    Comparison of model results suggests that progradation (as in the second and third sets of models) loads underlying ‘salt’ differentially, displaces it downdip and segments it. As it segments at the back, the ‘salt’ flows laterally to areas of lower loading by intruding through the thinner overburden units and forming secondary ‘salt’ sheets at the front. On the other hand, aggradation of uniform overburden segments a buoyant sheet into two-dimensional salt walls or stocks, as in the first set of models.

    Pressure–temperature estimates on the Tjeliken eclogite: new insights into the (ultra)-high-pressure evolution of the Seve Nappe Complex in the Scandinavian Caledonides2014Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 390, s. 369-384Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The metamorphic evolution of the Tjeliken eclogite, occurring within the Seve Nappe Complex of northern Jämtland (Swedish Caledonides), is presented here. The prograde part of the pressure and temperature (PT) path is inferred from the mineral inclusions (pargasitic amphibole) in garnet and intracrystalline garnet exsolutions in omphacite. Peak metamorphic conditions of 25–26 kbar at 650–700 °C are constrained from geothermobarometry for the peak-pressure assemblage garnet + omphacite + phengite + quartz + rutile, using the garnet–clinopyroxene Fe–Mg exchange thermometer in combination with the net-transfer reaction (6 diopside + 3 muscovite = 3 celadonite +2 grossular + pyrope) geobarometer, the average PT method of THERMOCALC and pseudosection modelling. Quartz inclusions with well-developed radial cracks were identified within omphacite, which suggest that the studied rock could have been buried down to the coesite stability field. Post-peak PT evolution is inferred from diopside–plagioclase symplectites and amphibole coronas around garnet. Previous studies in northern Jämtland suggest a substantial gap between the PTconditions of the Lower and Middle Seve nappes: 14–16 kbar and 550–680 °C and 20–30 kbar and 700–800 °C, respectively. The Tjeliken eclogite has been considered previously to be a part of Lower Seve by most authors, but the newPT data suggest that it may be an isolated klippe of Middle Seve.

    Prorotodactylus and Rotodactylus tracks: an ichnological record of dinosauromorphs from the Early-Middle Triassic of Poland2013Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 379, s. 319-351Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We present the first comprehensive description of Prorotodactylus and Rotodactylus dinosauromorph tracks from the Early and Middle Triassic of the Holy Cross Mountains, Poland. We describe and comprehensively figure tracks that have been mentioned briefly in previous accounts as well as new, recently discovered material, and analyse the variation and stratigraphic distribution of these specimens. Tracks have been recorded from four sites – Koszary, Stryczowice,Wiory and Baranow – which span the early Olenekian–early Anisian (c. 250–246 Ma).These tracks therefore represent an ichnological record of the evolutionary succession of early dinosauromorphs during the earliest part of their evolutionary history. Recognized track types include cf. Prorotodactylus isp., Prorotodactylus isp., Prorotodactylus mirus, Rotodactylus cursorius, Rotodactylus isp. and cf. Rotodactylus isp. At least three distinct Early and early Middle Triassic early dinosauromorph ichnofaunas can be recognized. The oldest, which is early Olenekianin age, is characterized by the presence of Prorotodactylus isp., cf. Prorotodactylus isp.and non-archosaurian archosauromorph or archosaur tracks (e.g. Synaptichnium isp., Protochirotherium isp.), recorded at the Stryczowice and Koszary sites. The following assemblage, recorded at the late Olenekian Wiory site, displays the highest ichnodiversity of dinosauromorphs, with fourtrack types present (Prorotodactylus isp., Prorotodactylus mirus, Rotodactylus cursorius and cf. Rotodactylus isp.). The youngest site, Baranow, includes Rotodactylus isp., as well as other larger dinosauromorph tracks. The first body fossil evidence of dinosauromorphs is a few million years younger than the youngest Polish tracks, so Prorotodactylus and Rotodactylus tracks currently provide the oldest record of dinosauromorph morphology, biology and evolution.

    Mesozoic structural evolution of the New Siberian Islands2017Ingår i: Geological Society Special Publication, ISSN 0305-8719, E-ISSN 2041-4927, Vol. 460Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The New Siberian Islands are affected by a number of Mesozoic tectonic events. Theoldest event (D1a) is characterized by NW-directed thrusting within the South Anyui SutureZone combined with north – south-trending sinistral strike-slip in the foreland during the Early Cre-taceous. This compressional deformation was followed by dextral transpression along north –south-trending faults, which resulted in NE – SW shortening in the Kotelny Fold Zone (D1b).The dextral deformation can be related to a north – south-trending boundary fault zone west ofthe New Siberian Islands, which probably represented the Laptev Sea segment of the AmerasiaBasin Transform Fault in pre-Aptian – Albian times. The presence of a transform fault west ofthe islands may be an explanation for the long and narrow sliver of continental lithosphere ofthe Lomonosov Ridge and the sudden termination of the South Anyui Suture Zone against the pre-sent Laptev Sea Rift System. The intrusion of magmatic rocks 114 myr ago was followed by NW –SE-trending sinistral strike-slip faults of unknown origin (D2). In the Late Cretaceous – Paleocene,east – west extension (D3) west of the New Siberian Islands initiated the development of the LaptevSea Rift System, which continues until today and is largely related to the development of the Eur-asian Basin.
