Constraints on yield strength in the oceanic lithosphere derived from observations of flexure

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...

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...

FLEXURE OF THE OCEANIC LITHOSPHERE IN THE VICINITY OF THE MARQUESAS ISLANDS by PAUL

While the visible portion of the Marquesas Islands is much smaller than that of the Hawaiian Islands, modelling of the shipboard gravity collected during the Crossgrain 2 expedition indicates that the rate of magma production by the two hotspots must be similar. The difference in effective elastic plate thickness beneath the two island chains causes the Marquesas to subside to a greater extent,...
