Continental Growth and Recycling in Convergent Orogens with Large Turbidite Fans on Oceanic Crust
Geosciences, 2013 Convergent plate margins where large turbidite fans with slivers of oceanic basement are accreted to continents represent important sites of continental crustal growth and recycling.

Burying Earth's Primitive Mantle in the Slab Graveyard
Geochemistry, Geophysics, Geosystems, 2021 The evolution of mantle composition can be viewed as a process of destruction whereby the initial chemical state is overprinted and reworked with time.

IODP Expeditions 304 & 305 Characterize the Lithology, Structure, and Alteration of an Oceanic Core Complex [PDF]
Scientific Drilling, 2006 More than forty years after the Mohole Project (Bascom, 1961), the goal of drilling a complete section through in situ oceanic crust remains unachieved.

Experimental Observation of a Calcium Silicon Double Carbonate
Angewandte Chemie, EarlyView.High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Communications Earth & Environment, 2023 Metamorphic soles found under allochthonous oceanic lithosphere, or ophiolites, are interpreted as derived from lower plate oceanic crust material accreted to upper plate mantle during intraoceanic subduction initiation.

Body wave dispersion characteristics of regional deep earthquake at Southern Ryukyus subduction zone [PDF]
E3S Web of Conferences, 2022 The convergent plate boundaries known as the subduction zone is the location where the cold, hydrate, and old oceanic plate subduct under the hot, dry, and young continental plate. The top of the oceanic plate, i.e. the oceanic crust usually is less than

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Frontiers in Earth Science, 2021 In this paper we present and analyze spreading-parallel seismic transects that image the oceanic crust in the eastern Gulf of Aden, from the Oman to the Socotra margins, across the active Sheba mid-oceanic ridge and between the Socotra-Hadbeen and ...

The hydrothermal power of oceanic lithosphere [PDF]
Solid Earth, 2015 We have estimated the power of ventilated hydrothermal heat transport, and its spatial distribution, using a set of recently developed plate models which highlight the effects of axial hydrothermal circulation and thermal insulation by oceanic crust ...

Synchronous oceanic spreading and continental rifting in West Antarctica
Geophysical Research Letters, 2016 Magnetic anomalies associated with new ocean crust formation in the Adare Basin off north‐western Ross Sea (43–26 Ma) can be traced directly into the Northern Basin that underlies the adjacent morphological continental shelf, implying a continuity in the
