Strength of the Iberian intraplate lithosphere: Cenozoic deformations and seismicity

Special Section: Intraplate Seismicity

Re-evaluated intensity distributions for the 1897 Mw 8.0 Shillong and the 1905 Mw 7.8 Kangra earthquakes, combined with geodetic constraints on rupture geometries, allow us to compare observed distributions of intensity with theoretically predicted shaking. The difference between predicted and observed shaking is interpreted in terms of the site response of the Ganges and Brahmaputra basins. Th...

Recycling deep cratonic lithosphere and generation of intraplate magmatism in the North China Craton

Early Cretaceous alkaline picrites and high-magnesium basalts from the North China craton provide evidence for recycling of continental lithosphere by density foundering. Both the picrites and basalts contain xenocrystic olivines with high Fo92-93 and low CaO (<0.10%), consistent with the lavas’ derivation from, or interaction with Archean mantle lithosphere. Most importantly, both the picritic...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

On the Yield Strength of Oceanic Lithosphere

The yield strength of oceanic lithosphere determines the mode of mantle convection in a terrestrial planet, and low-temperature plasticity in olivine aggregates is generally believed to govern the plastic rheology of the stiffest part of lithosphere. Because, so far, proposed flow laws for this mechanism exhibit nontrivial discrepancies, we revisit the recent high-pressure deformation data of M...
