Ductile flow in sub-volcanic carbonate basement as the main control for edifice stability: New experimental insights

Limestone in volcanic basements has been identified as a hazard in terms of edifice stability due to the propensity of calcite to decompose into lime and CO2 at high temperatures (>600 °C), causing a decrease in mechanical strength. To date, such hypoth ...

Effect of water on the frictional behaviour of cohesive rocks during earthquakes

Marie Estelle Solange Violay, Andrea Cavallo

Fluid-rock interactions can control earthquake nucleation and the evolution of earthquake sequences. Experimental studies of fault frictional properties in the presence of fluid can provide unique insights into these interactions. We report the first resul ...

Rock fragmentation mechanism by TBM cutter and TBM tunnelling under stressed grounds

Lijun Yin

With the advance of technology, TBMs are becoming more versatile and TBM tunnelling has become a common tunnelling method. As TBM tunnelling is a special excavation method depending on the interaction between machine and rock mass under a certain geologica ...

Pore fluid in experimental calcite-bearing faults: Abrupt weakening and geochemical signature of co-seismic processes

Marie Estelle Solange Violay

While it is widely recognized that fluids influence fault strength and earthquake nucleation, propagation and arrest, their effects on co-seismic sliding friction are only conjectured. To shed light on these effects, 55 high velocity (>1ms-1) friction e ...

Petrology and chemistry of the picritic shergottite North West Africa 1068 (NWA 1068)

Philippe Gillet

We report on the petrology and chemistry of North West Africa 1068 (NWA 1068), a shergottite recently recovered in Morocco. This meteorite has a total known mass of about 577 g and comprises 23 fragments. The largest fragment is a greenish-brown rock devoi ...
