Drip tectonics
WebOct 1, 2024 · The secular evolution of the Earth's crust is marked by a profound change in average crustal chemistry between 3.2 and 2.5 Ga. A key marker for this change is the transition from Archaean sodic granitoid intrusions of the tonalite-trondhjemite-granodiorite (TTG) series to potassic (K) granitic suites, akin (but not identical) to I-type granites that … WebDec 12, 2024 · Scientists have proposed strange theories like drip tectonics, where plates sag into the mantle like dripping fat, and plume tectonics, where superheated jets of solid mantle rise up, to explain Earth’s early history. Two new studies bring us closer to understanding what might have happened in those first billion or so years.

WebMar 15, 2016 · Plate Tectonics explains that there are three types of plate boundaries: divergent, where new plate is created; convergent, where plate is destroyed; and transform, where two plates slide past each other without plate being created or destroyed. There are clear rules for plate motion, specified by poles of rotation and angular plate velocities. WebTectonic plates move quite slowly: about as fast as your fingernails grow (up to ~10 cm per year). The Theory of Plate Tectonics explains the causes and nature of plate motions and interactions.

WebTectonic evolution of the dripping lithosphere. EXP-1 shows instability developing by 3.8My and associated surface sub- sidence of ~600m as the crust is pulled down (negative dynamic topography) by the dripping lithosphere (Fig. 2a). The crust thickens by 5km above the drip and this corresponds to a con- fined zone of shortening.
