Fast methane diffusion at the interface of two clathrate structures.
(Nature communications, 2017-10-20)Methane hydrates naturally form on Earth and in the interiors of some icy bodies of the Universe, and are also expected to play a paramount role in future energy and environmental technologies. Here we report experimental ... -
Faulting and Magmatic Accretion Across the Overlapping Spreading Center Between Vance Segment and Axial South Rift, Juan de Fuca Ridge
(Geochemistry, Geophysics, Geosystems, 2022-01-12)Plate divergence along mid‐ocean ridges is accommodated through faulting and magmatic accretion, and, at overlapping spreading centers (OSC), is distributed across two curvilinear overlapping ridge axes. One‐meter resolution ... -
Fe0-based alloys for Environmental Remediation: Thinking outside the Box

Feathery and network-like filamentous textures as indicators for the re-crystallization of quartz from a metastable silica precursor at the Rusey Fault Zone, Cornwall, UK
(Solid Earth, 2016)Hydrothermal quartz crystals, which occur in the Rusey Fault Zone (Cornwall, UK), show feathery textures and network-like filamentous textures. Optical hotcathodoluminescence (CL) analysis and laser ablation ... -
Field Trip F2: Sediments of the Ries Crater Lake (Miocene, Southern Germany)
(Dteutsche Gesellschaft für Geowissenschaften, Hannover2006-06)The Nördlinger Ries is a circular, flat depression of 22-24 km diameter separating the Jurassic limestone plateaus of the Franconian and Swabian Alb in Southwest-Germany. Its centre is located 110 km NW of Munich, 70 ... -
Findling Trissow
(Neubrandenburger Geologische Beiträge; Band 11)Der große Findling von Trissow wird mittels petrographischer Untersuchungen und Vergleichen als granatführender Cordieritgneis aus der Sörmlandmulde bestimmt und beschrieben. Weitere Funde des Gesteins in der Umgebung im ... -
Fine‐Sediment Erosion and Sediment‐Ribbon Morphodynamics in Coarse‐Grained Immobile Beds
(Water Resources Research, 2022-11-14)In rivers, fine sediments are often transported over immobile coarse grains. With low sediment supply, they tend to aggregate in longitudinal ribbons. Yet, the long‐term evolution of such ribbons and the influence of ... -
Fluid/rock interaction and mass transfer in continental subduction zones: constraints from trace elements and isotopes (Li, B, O, Sr, Nd, Pb) in UHP rocks from the Chinese Continental Scientific Drilling Program, Sulu, East China
(Contributions to Mineralogy and Petrology, 2011)In order to better understand the role of fluids during subduction and subsequent exhumation, we have investigated whole-rock and mineral chemistry (major and trace elements) and Li, B as well as O, Sr, Nd, Pb isotopes on ... -
Fluvial and permafrost history of the lower Lena River, north‐eastern Siberia, over late Quaternary time
(Sedimentology, 2022-09-29)Arctic warming and permafrost thaw visibly expose changes in the landscape of the Lena River delta, the largest Arctic delta. Determining the past and modern river regime of thick deltaic deposits shaping the Lena River ... -
Focused methane migration formed pipe structures in permeable sandstones: Insights from uncrewed aerial vehicle‐based digital outcrop analysis in Varna, Bulgaria
(Sedimentology, 2021-05-24)Focused fluid flow shapes the evolution of marine sedimentary basins by transferring fluids and pressure across geological formations. Vertical fluid conduits may form where localized overpressure breaches a cap rock ... -
Formation of Continental Microplates Through Rift Linkage: Numerical Modeling and Its Application to the Flemish Cap and Sao Paulo Plateau
(Geochemistry, Geophysics, Geosystems, 2021-04-22)Continental microplates are enigmatic plate boundary features, which can occur in extensional and compressional regimes. Here we focus on microplate formation and their temporal evolution in continental rift settings. To ... -
Formin Is Associated with Left-Right Asymmetry in the Pond Snail and the Frog
(Current Biology, 2016)While components of the pathway that establishes left-right asymmetry have been identified in diverse animals, from vertebrates to flies, it is striking that the genes involved in the first symmetry-breaking step remain ... -
