Movements on low-angle normal faults (LANF) are not predicted by traditional Anderson–Byerlee frictional fault mechanics. Our investigations centre on three normal fault systems active at distinct times during the regional extension of the Northern A...

Variations in the seawater 87Sr/86Sr curve through time can be caused by fluctuations in the strontium flux or variations in the isotopic ratio from at least six different sources and sinks. Thus, 12 or more parameters control each single measurement... Read More about Non-uniqueness and interpretation of the seawater 87Sr/86Sr curve.

Helium solubility in olivine and implications for high ³He/⁴He in ocean island basalts (2005)
Journal Article

High 3He/4He ratios found in ocean island basalts are the main evidence for the existence of an undegassed mantle reservoir1, 2, 3. However, models of helium isotope evolution depend critically on the chemical behaviour of helium during mantle meltin...

A unifying model of oceanic crustal development at slow spreading rates is presented in which accretion follows a cyclic pattern of magmatic construction and tectonic destruction, controlled by along-axis variation in melt supply and coupled to along...

The conversion of opal A to opal CT is a thermochemical diagenetic process that can cause kilometer-scale differential compaction and differential subsidence within clastic sedimentary basins. This is demonstrated for an opal A to opal CT conversion... Read More about Differential compaction and subsidence in sedimentary basins due to silica diagenesis: A case study.

[1] Despite their clear danger to humans, snow avalanches are hard to document. They occur in inaccessible and dangerous locations, often at times of bad weather. Observation instruments frequently malfunction in the harsh conditions or are destroyed... Read More about Air pressure data from the Vallée de la Sionne avalanches of 2004..

In-situ Os isotopes in abyssal peridotites bridge the isotopic gap between MORBs and their source mantle (2005)
Journal Article
Alard, O., Luguet, A., Pearson, N., Griffin, W., Lorand, J., Gannoun, A., …O’Reilly, S. (2005). In-situ Os isotopes in abyssal peridotites bridge the isotopic gap between MORBs and their source mantle. Nature, 436, 1005-1008. https://doi.org/10.1038/nature03902

Abyssal peridotites are assumed to represent the mantle residue of mid-ocean-ridge basalts (MORBs). However, the osmium isotopic compositions of abyssal peridotites and MORB do not appear to be in equilibrium1, 2, 3, 4, 5, 6, 7, 8, raising questions...
