Petrogenetic history and melt inclusion characteristics of mantle plume-derived ijolites from NE India: implications for multistage crystallization and occurrence of “nano-calciocarbonatites”

open access: yesProgress in Earth and Planetary Science, 2022
The Sung Valley ultramafic–alkaline–carbonatite complex (UACC) of Meghalaya, 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)

Evaluation of Error Propagation in Lead Isotope Analysis of Ancient Melt Inclusions by LA-MC-ICP-MS

open access: yesYankuang ceshi, 2015
Determination of Pb isotopes in melt inclusions by Laser Ablation -Multiple Collector-Inductively Coupled Plasma-Mass Spectrometry (LA-MC-ICP-MS) is limited to samples formed later than Mesozoic because U and Th signals are not monitored.

Optimization of flow control devices in a ten-strand billet caster tundish [PDF]

open access: yesChina Foundry, 2016
The physical model of a ten-strand billet caster tundish was established to study the effects of various flow control devices on the melt flow. Before and after the optimization of the melt flow, the inclusion removal in the tundish was evaluated by ...

Experimental investigation of hydrodynamics of melt layer during laser cutting of steel [PDF]

open access: yes, 2011
In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front in the case of laser cutting of

Chemical diffusion of fluorine in jadeite melt at high pressure [PDF]

open access: yes, 1984
The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 1400°C using diffusion couples of Jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion

Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]

open access: yes, 1985
The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.
