On the yield strength of oceanic lithosphere
WebLithospheric yield stress is a key parameter in controlling tectonic processes. Using high resolution, 2D numerical modeling, we calculate the yield stress for a range of conditions appropriate to the early-to-mid Archean Earth, including hotter mantle potential temperatures and Moho temperatures. We then evaluate its effect on generating tonalite-trondhjemite … Webestimates of the strength of the oceanic lithosphere. 1. Introduction The strength of Earth's lithosphere directly influences a wide variety of large‐scale geodynamic processes. Correspondingly, considerable effort has been focused on characterizing the strength of the rocks that com-prise the lithosphere through laboratory‐based ...

Webdifferent approaches should yield the same results. Figure 1. Schematic diagram illustrating different models for the long-term strength of continental lithosphere. In the crème-brûlée model, the strength is confined to the uppermost brittle layer of the crust, and compensation is achieved mainly by flow in the weak upper mantle.
