A Review of the Achievements in the Survey and Study of Ion-absorption Type REE Deposits in China
摘要
Abstract
Ion-adsorption REE deposits, which are widely distributed in southern China, are important because they supply valuable heavy REEs for global consumption. Like most other minerals, China's rare earth industry has experienced its ups and downs since 2011. However, a remarkable progress has been achieved in the survey and study of ion-adsorption REE deposits. Firstly, in the aspect of metallogenic theories, Chinese researchers have recognized that the deposits have multi-subtypes (e.g., ion-adsorption La deposit, ion-adsorption Eu deposit, ion-adsorption Dy deposit), metallogenic parent rocks (e.g., granitic rocks, pyroclastic rocks, and metamorphic rock), geological age of metallogenic parent rocks, stratigraphic horizon, metallogenic model, prospecting marks (e.g.,chemical index of alteration, loss on ignition), mineralization mechanism (e.g., magmatic crystallization, hydrothermal alteration), intrusive body, geological occurrence (intrusive or extrusive rocks). The deposits can also be discovered in high latitude or high altitude areas. Secondly, the exploration depths of weathering crust have greatly increased by using the Gannan drill, and REEs potential resources will be doubled. Remote sensing technique has been used for quick, accurate, dynamic investigation and prospecting of ion-absorbed REE deposits. The environmental effects of REEs mining have been comprehensively evaluated based on the continuous hydrochemical survey, and a new technology of controlling environmental pollution is provided. Finally, a number of prospecting targets and prospecting areas were delineated, and a number of medium and large-sized mineral areas were verified, and a breakthrough of prospecting in the Zhejiang, Fujian, Yunnan and Jiangxi provinces was achieved.关键词
