Theory of Decoupling in the Mixed Phase of Extremely Type-II Layered Superconductors

open access: yes, 2001
The mixed phase of extremely type-II layered superconductors in perpendicular magnetic field is studied theoretically via the layered XY model with uniform frustration. A partial duality analysis is carried out in the weak-coupling limit. It consistently

Komatiite genesis in the Archaean mantle, with implications for the tectonics of Archaean greenstone belts [PDF]

open access: yes
The presence of ultramafic lavas (komatiites) associated with Archean greenstone belts has been suggested to indicate very high increments (50-80%) of partial melting of the Archean mantle.

Petrology of Oligocene Lalehzar igneous rocks in the southeast of Saveh-Naein-Jiroft magmatic belt

open access: yesJournal of Economic Geology
Lalehzar igneous rocks are located in the southeast of Iran, the SE of Saveh-Naein-Jiroft magmatic belt. In this study, zircon U-Pb dating, and whole-rock geochemistry and Sr-Nd isotopic analyzes were performed on granitoid rocks (granite and ...

Shoshonitic enclaves in the high Sr/Y Nyemo pluton, southern Tibet: Implications for Oligocene magma mixing and the onset of extension of the southern Lhasa terrane [PDF]

open access: yes, 2020
Post-collisional potassic and high Sr/Y magmatism in the Lhasa terrane provides critical constraints on the timing and mechanism of subduction of Indian lithosphere and its role in the uplift of the Tibetan Plateau.

Partial Melting of Lower Oceanic Crust Gabbro: Constraints From Poikilitic Clinopyroxene Primocrysts

open access: yesFrontiers in Earth Science, 2018
Successive magma batches underplate, ascend, stall and erupt along spreading ridges, building the oceanic crust. It is therefore important to understand the processes and conditions under which magma differentiates at mid ocean ridges.

Non-equilibrium melting of partially differentiated asteroids: insights from partial melting experiments on L6 chondrite DAV01001

open access: yes, 2022
<p>Planetary differentiation in small bodies is believed to be ruled by several partial end-states that were dominated by low degrees of partial melting and melt segregation, before arriving at the formation of rocky planets. Having a better understanding of non-equilibrium melting processes in undifferentiated chondritic materials is ...

Radiogenic Heating as the Thermal Driver of Himalayan Crustal Heating During Prolonged Thickening

open access: yesGeochemistry, Geophysics, Geosystems
The thermal evolution of the crust during continental collision evolves from cold to hot with time, which impacts crustal reworking and differentiation.

Processing of bulk Bi-2223 high-temperature superconductor

open access: yesMaterials Research, 2005
The Bi2Sr2Ca2Cu3 O10+x (Bi-2223) is one of the main high temperature superconductors for applications. One of these applications is the Superconductor Fault Current Limiter (SCFCL), which is a very promising high temperature superconducting device. SCFCL'

Partial melting of amphibolite to trondhjemite near Ykutat, Alaska [PDF]

open access: yes
At Nunatak Fiord, 55 km NE of Yakutat, Alaska, a uniform layer of Cretaceous metabasalt approximately 3 km thick was metamorphosed to amphibolite facies and locally partially melted to trondhjemite pegmatite.
