Late Ordovician to early Devonian adakites and Nb-enriched basalts in the Liuyuan area, Beishan, NW China: Implications for early Paleozoic slab-melting and crustal growth in the southern Altaids

, 2012
We report newly-defined Nb-enriched basalts, adakites and dacites from the Beishan, NW China of the southern Altaids based on field, geochemical, isotopic and geochronology studies.

Late Cretaceous (ca. 90 Ma) adakitic intrusive rocks in the Kelu area, Gangdese Belt (southern Tibet): Slab melting and implications for Cu–Au mineralization

, 2012
The Gangdese Belt in southern Tibet (GBST) is a major Cu-Au-Mo mineralization zone that mostly formed after the India-Asia collision in association with the small-volume, though widespread, Miocene (18-10 Ma) adakitic porphyries. Cu-Au mineralization has

Transition of subduction-related magmatism from slab melting to dehydration at 2.5 Ga

, 2020
The Archean plate tectonics and subduction-related magmatism have been concerned for several decades. Here we investigate the Archean plate subduction from a new perspective, using the secular records of global-scale non-TTG (tonalite-trondhjemite ...

Partial melting of slab window margins: genesis of adakitic and non-adakitic magmas

Lithos, 2005
When a mid-ocean spreading ridge subducts, it typically splits apart at depth to form two tapered slab edges separated by asthenospheric mantle within a slab window.

Computer simulation of consumable melted slabs

Metallurgical Transactions, 1970
A mathematical model has been developed to simulate two-dimensional heat flow for a slab ingot produced as a remelted product. Various heat flow parameters have been studied to determine the influence of changes in them on local solidification time. The parameters which show the greatest influence are the heat transfer coefficient and the thickness of ...

Post-collisional adakitic volcanism in the eastern part of the Sakarya Zone, Turkey: evidence for slab and crustal melting

Contributions To Mineralogy and Petrology, 2013
New geochemical and isotopic data for post-collisional Early Eocene and Late Miocene adakitic rocks from the eastern part of the Sakarya Zone, Turkey, indicate that slab and lower crustal melting, respectively, played key roles in the petrogenesis of ...

Melt circulation in thin solidifying steel slab

Steel in Translation, 2010
Melt fluxes in the liquid core of thin solidifying steel slabs are analyzed, for two different nozzle configurations. The reliability of the analysis is ensured by taking account of turbulence on the basis of a two-parameter Launder-Spalding model and also by the universal numerical finite-element method.
