Geochemistry of mineralization with exchangeable REY in .

Mineralization with exchangeable rare earth element (REE) and yttrium (MEX-REY) has been recognized in the weathering profiles in South China since the early 1970's. This type of REY mineralization occurs in weathering profiles of parent rocks ranging in composition from granite to acidic volcanic rocks and lamprophyre.

Mesozoic Large-scale Mineralization and Multiple Lithospheric Extensions in South Chi

Abstract South China is the most important polymetallic (tungsten, tin, bismuth, copper, silver, antimony, mercury, rare metals, heavy rare earth elements, gold and lead‐zinc) province in China. This paper describes the basic characteristics of Mesozoic large‐scale mineralization in South China.

The Rare Earth Elements: Demand, Global Resources, and .

The rare earth elements (REE) have attracted much attention in recent years, being viewed as critical metals because of China’s domination of their supply chain. This is despite the fact that REE enrichments are known to exist in a wide range of settings, and have been the subject of much recent exploration.

Rare-earth element - Wikiped

A rare-earth element (REE) or rare-earth metal (REM), as defined by the International Union of Pure and Applied Chemistry, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium.[2] Scandium and yttrium are considered rare-earth elements because they tend to ...
