Seismic evidence for partial melt below tectonic plates [PDF]
Nature, 2020 The seismic low-velocity zone (LVZ) of the upper mantle is generally associated with a low-viscosity asthenosphere that has a key role in decoupling tectonic plates from the mantle. However, the origin of the LVZ remains unclear. Some studies attribute its low seismic velocities to a small amount of partial melt of minerals in the mantle, whereas ...

Phase transition of melt-vapor in the magnesium–tin system and its technological application [PDF]
Scientific ReportsAs a result of research using the boiling point method, the partial pressure of magnesium above Mg–Sn alloys was determined, represented by the temperature-concentration dependence.

Frontiers in Earth Science, 2023 In magma-rich continental rifts extension by magma intrusion is thought to accommodate much of the extension. We aim to constrain major melt reservoirs in the crust during magma-rich rifting by applying P-to-S receiver functions (RFs) using legacy ...

A Review of Subsurface Electrical Conductivity Anomalies in Magnetotelluric Imaging
Sensors, 2023 After 70 years of development, magnetotelluric (MT), a remote sensing technique for subsurface electrical resistivity imaging, has been widely applied in resource exploration and the deep tectonic evolution of the Earth.

Modelling S-Wave Velocity Structure Beneath the Central Main Ethiopian Rift Using Receiver Functions
Frontiers in Earth Science, 2022 We applied the receiver function (RF) technique on high-quality teleseismic earthquake data recorded by the RiftVolc broadband network from February 2016 to October 2017.

Melting and Crystallization of Ice in Partially Filled Nanopores [PDF]
The Journal of Physical Chemistry B, 2011 We investigate the melting and formation of ice in partially filled hydrophilic and hydrophobic nanopores of 3 nm diameter using molecular dynamics simulations with the mW water model. Above the melting temperature, the partially filled nanopores contain two water phases in coexistence: a condensed liquid plug and a surface-adsorbed phase.

X-ray diffraction study of structure of CaO-Al2O3-SiO2 ternary compounds in molten and crystalline states [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2020 Anorthite and gehlenite crystalline structure and short-range order of anorthite melt have been studied by X-ray diffraction in the temperature range from room temperature up to ~ 1923 K.
