This mantle appears to have been an important source component involved in the formation of the primitive crust during most of the Hadean and Eoarchean eons.doi:10.1016/j.epsl.2016.02.055Elsevier B.V.Earth & Planetary Science LettersO'Neil, J., Rizo, H., Boyet, M., Carlson, R. W., ...
Dispersion curves of Rayleigh and Love waves with periods ranging from 20 to 70 seconds are calculated for various spherical earth models with superficial sea water. The model 6E and the model 8099 are adopted as standard continental and oceanic structures and the crustal thickness is parametrically...

NE, India, is a result of magmatic activity related to the Kerguelen mantle plume spanning from 101 to 115 Ma. In the present study, an integrated crystal size distribution (CSD), mineral chemistry, and melt inclusion analysis are carried out on the ijolites present within this UACC. The C...

Limestone has long fascinated earth scientists because of its richfossilcontent. Much knowledge of theEarth’schronology and development has been derived from the study of fossils embedded in limestone and other carbonate rocks. Limestone also has considerable commercial importance. Limestones enriched in...
Marine ecosystem, complex of living organisms in the ocean environment. Marine waters cover two-thirds of the surface of the Earth. In some places the ocean is deeper than Mount Everest is high; for example, the Mariana Trench and the Tonga Trench in the
As part of the Mediterranean-Himalayan geothermal belt, Tibet, Yunnan, and western Sichuan in China host the most high-temperature geothermal systems [10,11,12,13]. The Yunnan Rehai volcanic geothermal system has a mantle-derived magmatic heat source. There are non-volcanic high-temperature ...

The lower crustal high-velocity zone (HVZ) in the southern Okinawa Trough, with Vp of 6.8-7.3 km/s, is a remarkable manifestation of the mantle material upwelling and accretion to the lower crust. This confirms that the lower crustal high-velocity mantle accretion is developed in the southern...
