Geometrical control of fluid flow through single carbonate fracture

Fluid flow through single rough surface is critical for many geophysical processes and engineering applications. Thus, relations between flow and surrounding fracture geometry will be investigated. Four pairs of engineered Carrara marble surfaces with diff ...

Composition and superposition of alluvial deposits drive macro-biological soil engineering and organic matter dynamics in floodplains

Claire Guenat, Pascal Turberg, Rodolphe Schlaepfer, Renée-Claire Le Bayon, Andreas Cedric Schomburg

Soil structure formation in alluvial soils is a fundamental process in near-natural floodplains. A stable soil structure is essential for many ecosystem services and helps to prevent river bank erosion. Plants and earthworms are successful soil engineering ...

Plagioclase Glomerocrysts: taking the pulse of volcanic eruptions

Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy

Volcanic eruptions result from complex interplay of magmatic processes including the ascent and storage of magma in the crust, volatile exsolution and crystallization. The dynamics of crystallization in shallow subvolcanic systems and the consequences of i ...

Atomistic study of hydrogen embrittlement of grain boundaries in nickel: I. Fracture

William Curtin, Ali Tehranchi

Hydrogen ingress into a metal is a persistent source of embrittlement. Fracture surfaces are often intergranular, suggesting favorable cleave crack growth along grain boundaries (GBs) as one driver for embrittlement. Here, atomistic simulations are used to ...

Unique large diamonds in a ureilite from Almahata Sitta 2008 TC3 asteroid

Philippe Gillet

The Almahata Sitta MS-170 ureilite (a piece of a breccia originating from the asteroid, 2008 TC3) consists mainly of olivine, with many diamond and graphite grains existing between the olivine grains. The occurrences of the diamonds are unique; i.e., (i) s ...

Nanotextures of aragonite in stromatolites from the quasi-marine Satonda crater lake, Indonesia

Anders Meibom, Jaroslaw Hubert Stolarski

Stromatolites have been extensively used as indicators of ancient life on Earth. Although much work has been done on modern stromatolites, the extent to which biological processes control their structure, and the respective contributions of biological and ...

High-resolution AFM imaging of intact and fractured trabecular bone

Georg Fantner

Nanoscale structural analyses of biomineralized materials can frequently help elucidate important structure-function relationships in these complex organic-inorganic composites. Atomic force microscope (AFM) imaging of the exterior surface of trabecular bo ...

The basaltic shergottite Northwest Africa 856: Petrology and chemistry

Philippe Gillet

We report on the discovery of a new shergottite from South Morocco. This single stone weighing 320 g is referenced as Northwest Africa (NWA) 856 with Djel Ibone as a synonymous name. It is a fresh, fine-grained basaltic rock consisting mainly of two pyroxe ...

Cataclastic fault rocks in underground excavations

Christoph Bürgi

The present study makes part of a research project on the geological and geomechanical characterisation of weak cataclastic fault rocks encountered in underground excavation sites in the Alps. The project is composed of a geological and a geomechanical par ...
