火山黏土型锂矿成矿作用研究进展与启示
Metallogenesis of volcanic clay-type lithium deposits in the calderas of Southeast Coastal China and its implications
摘要
Abstract
Lithium is a critical strategic mineral and can be primarily categorized into three types:hard rock,brine,and clay.The volcanic clay-type lithium deposits recently discovered in acidic volcanic rock areas repre-sent an important new lithium resource.However,limited research on the mineralization processes of such de-posit has hindered the understanding on their prospecting potential.This paper systematically summarizes four large volcanic clay-type lithium deposits discovered in recent years in Europe and the United States.By tracing the sources of mineral-forming materials,enrichment processes,and geodynamic settings of these deposits,as well as adopting the methodologies including infrared spectroscopy scanning and comparative analysis of alter-ation mineral assemblages,the prospecting potential for volcanic clay-type lithium deposits in the acidic volcanic rock areas of Southeastern China is further analyzed.This study provides new insights for theoretical research and exploration on this type of lithium deposit.关键词
