WebMar 19, 2016 · The mantle viscosity is likely to be non-linear, e.g., it could be as low as 10 18 Pa ⋅ s (over shorter time scales) or as high as 10 21 Pa ⋅ s (over longer time scales). In any case the values reported in the literature are somewhere between 10 18 − 10 21 Pa ⋅ s and these are based on studies from earthquakes, glacial rebound etc. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene. The lithosphere-asthenosphere boundary is conventionally taken at the 1,300 °C (2,370 °F) isotherm.

Since it is rigid and … WebHorizontal stresses within the plastic asthenosphere (located from 100 to 400 km below the terrestrial surface) create extension within the 100-km thick lithosphere, breaking it into a series of internally brittle plates. If extension occurs within continental crustal material, terrestrial or maritime rift basins are produced.

WebSuch stresses can be induced by cooling of rock (volume decreases as temperature decreases) or by relief of pressure as rock is eroded above thus removing weight. Joints provide pathways for water and thus pathways for chemical weathering attack on rocks. If new minerals are precipitated from water flowing in the joints, this will form a vein.
