Quantifying the nature of ore-forming fluids in the ...

2021-10-13  Carbonatite-related rare earth element (REE) deposits are major hosts of REE resources. REE mineralization in these deposits is generally associated with hydrothermal systems at late stages of carbonatite evolution, but the nature of ore-forming fluids and their role in concentrating REEs are not well understood. In this study, we quantified the nature of ore-forming fluids by conducting a ...

2010-10-1  1. Introduction. Carbonatites are defined in the IUGS system of classification as igneous rocks composed of more than 50 modal per cent primary (magmatic) carbonate and containing less than 20 wt.% SiO 2 (Le Maitre, 2002).Varieties of carbonatite are named on the basis of the dominant carbonate mineral, e.g. calciocarbonatite, magnesiocarbonatite, and ferrocarbonatite (Woolley and
