  • Seismological station OGDI of the Résif-RLBP-Rap network, located in the commune of Dignes-les-bains (Alpes-de-Haute-Provence)
    2011
    Co-Authors: Mickaël Langlais
    Abstract:

    This image gives an overview of the installation of the broadband velocity sensor carried out during the modernization of the site OGDI of the Résif-RLBP-Rap network. This station is located in the commune of Dignes-les-bains (Alpes-de-Haute-Provence), within the Geological Reserve. The site has been instrumented since 1995. In 2010/2011, as part of the INTERREG RISE project, it was completely modernised (new instruments, switch to ADSL, installation of an electrical cabinet in the cabin). This site hosts two types of instruments, an accelerometer (Rap) and a velocimeter (RLBP). It is part of the French seismological and geodetic network Résif, a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Internal Earth. Résif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Résif is part of the European (EPOS - European Plate Observing System) and global systems of instruments used to image the Earth's interior as a whole and to study many natural phenomena.

This site hosts two types of instruments, an accelerometer (Rap) and a velocimeter (RLBP). This photo shows the Nanometrics Trillium120PA sensor installed, levelled and oriented before closing the TANK V1.0 barometric insulation tank. This tank was developed at ISTerre in collaboration with the IPGP technical team. The purpose of this vessel is to limit the influence of pressure and temperature variations on the wideband velocity sensor. Thanks to this additional isolation we are able to improve the quality of the recorded signals by lowering the noise level in some frequency bands (long periods) by about 20dB.

    Abstract:

    This image shows the installation of the granite slab used as the base for the TANK V1.0 barometric insulation tank developed at ISTerre in collaboration with the IPGP technical team. The purpose of this vessel is to limit the influence of pressure and temperature variations on the broadband velocity sensor. Thanks to this additional isolation we are able to improve the quality of the recorded signals by lowering the noise level in some frequency bands (long periods) by about 20dB. This tank is installed in a concrete nozzle buried on the site of the seismological station OGDI of the Résif-RLBP-Rap network. This station is located in the commune of Dignes-les-bains (Alpes-de-Haute-Provence), within the Geological Reserve. The site has been instrumented since 1995.

This site hosts two types of instruments, an accelerometer (Rap) and a velocimeter (RLBP). In this image we can see the nozzle that houses the large band velocity sensor. The cabin in the background houses the cabinet with the electronic equipment and the accelerometer sensor.

  • Emsian vertebrate microremains from the Zinzilban section, Uzbekistan
    Palaeoworld, 2009
    Co-Authors: Carole J Burrow, Alexander Ivanov, Olga Rodina
    Abstract:

    Abstract Fossil vertebrate microremains were collected from 22 sampling levels between the Pragian/Emsian boundary stratotype point (base of the kitabicus Conodont Zone) and the mid-Emsian ( excavatus Conodont Zone) in the Zinzilban section, Kitab State Geological Reserve, Uzbekistan. The material includes scales of acanthodians Radioporacanthodes liujingensis (Wang) and Canadalepis basdenae Burrow, as well as chondrichthyan scales, and scales and dermal bone fragments of acanthothoracid placoderm Xiejiawanaspis pinus Burrow et al., other indeterminate acanthothoracids, and probably a buchanosteid. This restricted fauna shows the closest resemblance with contemporaneous vertebrate assemblages from Sichuan Province in China, Salair in Siberia, Russia, and southeastern Australia.

  • Turystyka w rezerwacie geologicznym „Prządki” w województwie podkarpackim
    2014
    Co-Authors: Z Wnuk, Maria Ziaja
    Abstract:

    Tourism in Geological Reserve „Prządki” in the Podkarpackie Voivodeship Podkarpackie Voivodeship belongs to one of the most attractive touristic regions of Poland, what is proved by the researches led in 2007 by Polish Tourism Development Agency S.A (it takes the second place after pomorskie voivodeship). Unique and valuable nature regions deserve special attention. Among protected areas there are 94 nature Reserves. Special attention deserves Geological Reserve ‘Przadki’, which is the most often visited by tourists in podkarpackie voivodeship. The Reserve is 13,63 ha in area and it was created in 1957 through a directive issued by Ministry of Forestry and Timber Industry. The aim of its creation was: “preservation, for scientifi c and scenic reasons, of the group of sandstone rocks marked by characteristic forms created by wind erosion”. The area of the Reserve is situated in district Korczyna, on the border of Czarnorzeki village and Korczyna, by the road Krosno- Rzeszow. It is in the Dynowskie Foothills on the eastern part of the ridge being a watershed for Marcinek and Black streams. The highest point in the Reserve reaches 520 m above sea level. The Reserve is situated in the area of Czarnorzecko-Strzyzowski Landscape Park and it is its one of the most signifi cant attractions, the group of unique rocky inselbergs altogether with the nearby forest belong to them. Developing tourism industry in a regional aspect, it is necessary to discern the infl uence of tourists on the natural environment, as well as the control of effects in environmental changes caused by tourism.

  • Plesiosaur remains associated with a rich marine fauna from the Albian of southeastern France
    2018
    Co-Authors: Peggy Vincent, Anne-sabine Grosjean, Guillaume Suan, Baptiste Suchéras-marx, KÉvin Janneau, Myette Guiomar, Didier Bert, Vincent Perrier, Guillaume Guinot, Jorge Ferreira
    Abstract:

    The Early-Late Cretaceous transition (Late Albian-Early Cenomanian; ~100 Ma) witnessed marked environmental changes and a deep reorganization of the marine fauna. Nevertheless, the impact of these environmental and biotic changes on Eurasian marine vertebrates remains poorly understood, as specimens from this area are mostly represented by fragmentary and isolated remains occurring in reworked, bonebed-like deposits. Here we report vertebrate remains from an upper Albian marine fossiliferous bed from the Geological Reserve of Digne (Alpes-de Haute-Provence, southeastern France), recovered with diverse invertebrate species (ammonoids, belemnoids, brachiopods and inoceramid bivalves). The fossiliferous bed consists of glauconitic marls enriched in planktic foraminifera and occurs within an expanded and monotonous succession of micaceous marls interbedded with silty carbonate levels that were deposited in the pelagic domain of the SE French Basin. The ammonite fauna is quite exceptional by its abundance, diversity and quality of preservation (i.e., large specimens preserving very fragile shell features that are generally not fossilized) and indicate that the investigated bed belong to the Mortoniceras fallax ammonite Biozone (Middle-Late Albian). The diverse vertebrate fauna consists of chondrichthyans, ichthyosaurs and plesiosaurs. Chondrichthyans are represented by five shark species belonging to the order Lamniformes. This shark assemblage is dominated by Sphenodus teeth and comprises predator taxa probably living in temperate waters and indicative of open marine settings. The site yielded a large, partial post-cranial plesiosaur skeleton with articulated elements probably belonging to an elasmosaurid (long necked) taxa and representing one of the most complete Albian plesiosaur specimen known from Europe. These findings indicate that this new paleontological site holds promising clues about the evolutionary history of major groups of marine vertebrates near the Early-Late Cretaceous transition.
