阿根廷Tres Quebradas盐湖锂矿地质特征及资源评价
Geological characteristics and resource evaluation of Tres Quebradas brine lithium mine,Argentina
摘要
Abstract
The lithium triangle countries of South America have become a global hotspot for lithium resource invest-ment in recent years.Among these,the Tres Quebradas Salar lithium project,located in the Catamarca Province of northwestern Argentina,is a recently completed and currently operating significant lithium brine mine.Howev-er,there is still limited research on its geological characteristics and resource evaluation.Through a comprehen-sive analysis of the geological characteristics of the brine lithium deposit,core logging from exploration drilling,and geophysical data interpretation,six lithium-rich brine aquifer units have been delineated.Based on pumping test results,key hydrogeological parameters,including lithium grade,hydroconductibility coefficient,permeabili-ty coefficient and specific yield(Sy)of each aquifer unit,were systematically analyzed.The results indicate that this deposit represents a high-quality salar-type lithium resource within the South American lithium triangle re-gion.On this basis,the study further proposes that the evaluation of lithium resources in salars should adhere to the guidelines for the geological exploration of salt lakes and saline mineral deposits,with a focus on identifying the controlling factors of lithium mineralization and the geological characteristics of lithium-rich brine aquifer units.Additionally,pumping tests should be utilized to establish the relationships between key hydrogeological parameters such as hydroconductibility coefficient and specific yield,providing a scientific foundation for the de-velopment and utilization of saline lithium resources.关键词
