Magnetic properties of REE fluorcarbonate minerals and their implications for minerals processing

open access: yesMinerals Engineering, 2019
Abstract Rare earth elements (REE) are considered as critical metals for electronics and green technology. The REE fluorcarbonates are one of the main REE ore minerals, common in many different types of REE deposit and yet some of their fundamental properties have still not been determined.

Origin of heavy rare earth mineralization in South China

open access: yesNature Communications, 2017
Heavy rare earth elements (HREE) are an important global resource for many industries. Here, Xuet al. have discovered new REE minerals, which represent oxidized REE-rich fluids that metasomatized granites resulting in an enrichment of HREE, therefore ...

Two discrete stages of fenitization in the Lizhuang REE deposit, SW China: Implications for REE mineralization

open access: yesOre Geology Reviews, 2021
Abstract Fenitization is an alkali metasomatism that widely occurs in and around the alkaline-carbonatite complex, and is closely associated with rare earth elements (REE) mineralization. However, the origin and nature of the fenitizing fluids and its role in REE mineralization are poor understood.

Trends in Ocean S‐Isotopes May Be Influenced by Major LIP Events

open access: yesGeophysical Monograph Series, Page 341-376., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
