A potential explanation of this process states the resultant solidification of the mantle edge took place approximately 4.43 Ga. WebThese brittle deformation mechanisms are favored at high stress and low P–T conditions featuring upper crust, where confining pressure is not high enough to suppress the initiation and growth of fractures and thermally activated plasticity is …
WebMay 6, 2024 · At the Earth’s surface, rocks usually break quite quickly, but deeper in the crust, where temperatures and pressures are higher, rocks are more likely to deform plastically. Sudden stress, such as a hit with a hammer, is more likely to make a rock break. Stress applied over time often leads to plastic deformation. GEOLOGIC STRUCTURES WebAbstract.
