title: New experimental dataset for partial dam-break floods over mobile beds

description: An experimental investigation is presented on partial dam-break floods over mobile beds, with different bed sediment compositions and initial upstream and downstream water levels. Detailed measurements were carried out, including water level evolution, final bed topography and bed surface sediment composition. Intense scour occurred immediately downstream from the dam, followed by significant deposition and small bed forms which were only observed in cases with non-uniform sediment. Also, final bed sediment surface showed a general coarsening trend in the intense scour and deposition areas and a coarse-fine-coarse structure in the remaining reach with small bed forms. The effects of the bed sediment composition and of the difference between initial upstream and downstream water levels on bed deformation are evaluated. This work facilitates new understanding of dam-break floods over mobile beds especially with non-uniform sediment, and provides a new experimental dataset which can be exploited to underpin the development of mathematical models.

title: Tsunamis generated by fast granular landslides: 3D experiments and empirical predictors

description: Landslides falling into water bodies can generate impulsive waves, which are a type of tsunamis. The propagating wave may be highly destructive for hydraulic structures, civil infrastructure and people living along the shorelines. A facility to study this phenomenon was set up in the laboratory of the Technical University of Catalonia. The set-up consists of a new device releasing granular material at high velocity into a wave basin. A system employing laser sheets, high-speed and high-definition cameras was designed to accurately measure the high velocity and geometry of the sliding mass as well as the produced water displacement in time and space. The analysis of experimental data helped to develop empirical relationships linking the landslide parameters with the produced wave amplitude, propagation features and energy, which are useful tools for the hazard assessment. The empirical relationships were successfully tested in the case of the 2007 event that occurred in Chehalis Lake (Canada).

title: Syllids inhabiting holdfasts of <i>Lessonia spicata</i> in Central Chile: diversity, systematics, and description of three new species

description: The diversity of syllid polychaetes inhabiting holdfasts of the brown algae <i>Lessonia spicata</i> in Central Chile was investigated. We found 12 species, belonging to the genera <i>Syllis</i>, <i>Amblyosyllis</i>, <i>Proceraea</i> and <i>Salvatoria</i> within the internal cavities of 14 holdfasts collected from the intertidal and subtidal zones of exposed rocky shores. This is the first record of syllid polychaetes living in association with the kelp <i>L. spicata</i>. In addition, we provide the descriptions of three new species, <i>Syllis albae</i> sp. nov., <i>Syllis tamarae</i> sp. nov. and <i>Syllis tripantu</i> sp. nov. discovered from the holdfast faunal assemblage. We describe their phylogenetic position and evolutionary relationships with other species within the genus <i>Syllis</i>, which were evaluated by phylogenetic analyses. Additionally, we provide new biogeographic information and ecological data, including updated distribution limits and habitat preferences for all identified species. This study highlights the importance of kelp holdfasts as hotspots of syllid diversity and suggests the potential use of associated Syllidae assemblages as tools for monitoring changes in the marine ecosystem that affect species distribution. http://zoobank.org/References/EE82D79E-1C24-4807-BBC7-C3BCBE343A47http://zoobank.org/urn:lsid:zoobank.org:act:93832177-4F4D-4BF1-925D-AC6DD7EE72CDhttp://zoobank.org/urn:lsid:zoobank.org:act:74E5DCF6-6D4E-4B00-ABF9-EA4E82408A26http://zoobank.org/urn:lsid:zoobank.org:act:7CAB9F72-7577-4C8F-AE03-093874603F67

title: Cryptic species, taxonomic inflation, or a bit of both? New species phenomenon in Sri Lanka as suggested by a phylogeny of dwarf geckos (Reptilia, Squamata, Gekkonidae, <i>Cnemaspis</i>)

description: We evaluated the status of 16 of 22 recognized Sri Lankan <i>Cnemaspis</i> Strauch species, and flagged overlooked diversity with two mitochondrial (cyt <i>b</i> & ND2) and two nuclear markers (RAG1 & PDC) totalling 2829 base pairs. A fossil-calibrated timetree and sampling of other South Asian <i>Cnemaspis</i> provide insights into the diversification of the genus in peninsular India and Sri Lanka. Phylogenetic analyses consistently inferred two broad clades within South Asian <i>Cnemaspis</i>, with Sri Lankan species in two clades, which we call the <i>podihuna</i> and <i>kandiana</i> clades. Each Sri Lankan clade as a whole is sister to Indian taxa and nested within Indian lineages. <i>Cnemaspis modigliani</i> Das from Indonesia is a member of the <i>kandiana</i> clade. This suggests a minimum of two dispersal events between India and Sri Lanka and one between Sri Lanka/India and South-east Asia. South Asian <i>Cnemaspis</i> date back to at least the Eocene, in Sri Lanka to the early Miocene, with late Miocene diversification in the <i>kandiana</i> clade. All but one of the named species we sampled is likely to be valid, and 10 divergent unnamed lineages may warrant specific recognition. A resolution of Sri Lankan <i>Cnemaspis</i> taxonomy will require thorough sampling and the use of both morphological and molecular data.

title: The nature of gold-bearing fluids in Atud gold deposit, Central Eastern Desert, Egypt

description: Electron microprobe analyses of gold and associated ore minerals as well as stable isotope analyses of sulphide and carbonate minerals were performed in order to determine the metal and fluid sources and temperature of the mineralizing systems to better understand the genesis of the Atud gold deposit hosted in the metagabbro–diorite complex of Gabal Atud (Central Eastern Desert, Egypt). The gold can be classified as electrum (63.6–74.3 wt.% Au and 24.6–26.6 wt.% Ag) and is associated with arsenopyrite and As-bearing pyrite in the main mineralization (gold-sulphides) phase within the main mineralized quartz veins and altered host rocks. Based on the arsenopyrite geothermometer, As-contents (29.3–32.7 atom%) in arsenopyrite point to deposition in the Log ƒ<sub>S2</sub> and T ranges of −10.5 to −5.5 and 305–450°C, respectively, during the main mineralizing phase. Based on the <i>δ</i><sup>34</sup>S isotopic compositions of the sulphides, they are originated from magmatic fluids in which the sulphur is either sourced directly from magma or remobilized from the magmatic rocks (gabbroic rocks). On the other hand, calcite formed from fluids having mainly magmatic mixed with variable metamorphic signatures based on its <i>δ</i><sup>13</sup>C and <i>δ</i><sup>18</sup>O values. This work concluded that the gold-bearing ores at Atud deposit have magmatic sources leaching from the country intrusive rocks during water/rock interactions then remobilized during a metamorphic event. Therefore, the Atud gold deposit is classified as an intrusion-related gold deposit, in which the gabbro–diorite host intrusion acted as the source of metals which were mobilized and deposited as a result of the effects of NW–SE shearing.

title: Tuning luminescent properties of a metal organic framework by insertion of metal complexes

description: We report the preparation and characterisation of new emissive materials based on the insertion of platinum(II) and iridium(III) complexes inside the Al(OH)(bipyridine dicarboxylate) metal organic framework (MOF-253). Guest incorporation is performed by coordination of a metal complex precursor, and provides increased robustness to the system compared to guest inclusion by its physical diffusion. Powder X-ray diffraction analysis highlights the high degree of crystallinity of the materials, with a complete change in the lattice parameters upon metal complex insertion. The photophysical properties of the resulting materials were thoroughly investigated. This synthetic approach is particularly attractive since, as we show, it is possible to tune the emission maxima of our materials over the entire visible range.

title: Oblique wedge extrusion of UHP/HP complexes in the Late Triassic: structural analysis and zircon ages of the Atbashi Complex, South Tianshan, Kyrgyzstan

description: The exhumation and tectonic emplacement of eclogites and blueschists takes place in forearc accretionary complexes by either forearc- or backarc-directed extrusion, but few examples have been well analysed in detail. Here we present an example of oblique wedge extrusion of UHP/HP rocks in the Atbashi accretionary complex of the Kyrgyz South Tianshan. Our field mapping and structural analysis demonstrate that the Atbashi Eclogite–Blueschist Complex is situated in a complicated duplex formed by a northerly dextral transpression system and a southerly sinistral transtension system. The two major shear systems suggest that the Atbashi Complex was extruded obliquely southwestwards during eastward penetration of the southern tip of the Yili–Central Tianshan Arc of the Kazakhstan Orocline during the Late Triassic. Also, we report new zircon U–Pb metamorphic ages of four eclogites and one garnet-bearing quartz-schist from the Atbashi complex of 217–221 Ma and 223.9 Ma, respectively, suggesting that the main extrusion was later than previously proposed and that the final orogenesis was not completed until the Late Triassic. The HP/UHP rocks have an oblique plunge to the NE and extrusion took place southwestwards during escape tectonics along the South Tianshan accretionary wedge in the Late Triassic. Our work shows that the movement of HP/UHP rocks had a 3D style with an arc-parallel structure, and sheds light on earlier 2D models with either forearc- or backarc-directed extrusions, which indicates that more systematic structural and geochronological work is needed to characterize the accretionary tectonics of many orogens around the world. Our data on the timing of extrusion and emplacement of the Atbashi Eclogite–Blueschist Complex also help to resolve the long-standing controversy about the time of terminal orogeny of the Central Asian Orogenic Belt.

title: Late Oligocene–Miocene mantle upwelling and interaction inferred from mantle signatures in gabbroic to granitic rocks from the Urumieh–Dokhtar arc, south Ardestan, Iran

description: The south Ardestan plutonic rocks constitute major outcrops in the central part of Iran’s Cenozoic magmatic belt and encompass a wide compositional spectrum from gabbro to granodiorite. U–Pb laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) dating of zircon three granodiorites yielded ages of 24.6 ± 0.1, 24.6 ± 0.1, and 24.5 ± 0.1 Ma. For tonalitic rocks, internal Rb–Sr isochron ages (biotite, feldspars) indicate cooling ages of 20.4 ± 0.1, 20.5 ± 0.1, and 22.3 ± 0.1 Ma, which are slightly younger than the zircons’ ages. The limited variations in their Sr–Nd isotope ratios indicate derivation from an asthenospheric mantle source. A geodynamic model is presented in which late Oligocene–Miocene rollback of the Neotethyan subducting slab triggered asthenospheric upwelling and partial melting in the south Ardestan. These melts were subsequently modified through fractional crystallization and minor crustal contamination en-route to the surface. Plagioclase + orthopyroxene-dominated fractional crystallization accounts for differentiation of gabbro to gabbroic diorite, whereas fractionation of clinopyroxene, titanomagnetite, and orthopyroxene led to differentiation of gabbroic diorite to diorite. Amphibole fractionation at deeper levels led to the development of tonalites.

title: The Proterozoic evolution of northern Siberian Craton margin: a comparison of U–Pb–Hf signatures from sedimentary units of the Taimyr orogenic belt and the Siberian platform

description: Identifying the cratonic affinity of Neoproterozoic crust that surrounds the northern margin of the Siberian Craton (SC) is critical for determining its tectonic evolution and placing the Craton in Neoproterozoic supercontinental reconstructions. Integration of new U–Pb–Hf detrital zircon data with regional geological constraints indicates that distinct Neoproterozoic arc-related magmatic belts can be identified within the Taimyr orogen. Sedimentary rocks derived from 970 to 800 Ma arc-related suites reveal abundant Archean and Paleoproterozoic detritus, characteristic of the SC. The 720–600 Ma arc-related zircon population from the younger Cambrian sedimentary rocks is also complemented by an exotic juvenile Mesoproterozoic zircon population and erosional products of older arc-related suites. Nonetheless, numerous evidences imply that both arcs broadly reworked Siberian basement components. We suggest that the early Neoproterozoic (ca. 970–800 Ma) arc system of the Taimyr orogen evolved on the active margin of the SC and probably extended along the periphery of Rodinia into Valhalla orogen of NE Laurentia. We also suggest the late Neoproterozoic (750–550 Ma) arc system could have been part of the Timanian orogen, which linked Siberia and Baltica at the Precambrian/Phanerozoic transition.
