摘要

英国阿伯丁郡的下泥盆世植物岩Rhynie Chert由温泉系统沉积的烧结矿组成。像许多现代温泉一样，Rhynie地热系统富含锂，其二氧化硅矿床比其他当前或化石烧结矿更富含锂。二十个Rhynie烧结矿样品的平均锂含量为255ppm。高值意味着泉水中锂含量异常。该燧石岩与同一地区的伟晶岩、花岗岩共同与晚加里东期富锂岩浆岩套有关，为该岩浆岩套的地表表现。这些测量结果表明，古温泉矿床可以为锂的勘探提供有价值的数据。补充资料:https://doi.org/10.6084/m9.figshare.c.6756506

Surface expression of Late Caledonian magmatic lithium concentration, in the Rhynie Chert, UK

The Lower Devonian plant-bearing Rhynie Chert, Aberdeenshire, UK, consists of sinters deposited by a hot spring system. Like many modern hot springs, the Rhynie geothermal system was lithium-rich, and its silica deposits are richer in lithium than other current or fossil sinters. Twenty samples of Rhynie sinter have a mean content of 255 ppm lithium. The high values imply exceptional lithium contents in the spring waters. Together with pegmatites and granites in the same region, the chert is related to a lithium-rich Late Caledonian magmatic suite, of which it is a surface expression. The measurements suggest that ancient hot spring deposits could provide valuable data during the exploration for lithium. Supplementary material: https://doi.org/10.6084/m9.figshare.c.6756506

期刊介绍： Geochemistry: Exploration, Environment, Analysis (GEEA) is a co-owned journal of the Geological Society of London and the Association of Applied Geochemists (AAG). GEEA focuses on mineral exploration using geochemistry; related fields also covered include geoanalysis, the development of methods and techniques used to analyse geochemical materials such as rocks, soils, sediments, waters and vegetation, and environmental issues associated with mining and source apportionment. GEEA is well-known for its thematic sets on hot topics and regularly publishes papers from the biennial International Applied Geochemistry Symposium (IAGS). Papers that seek to integrate geological, geochemical and geophysical methods of exploration are particularly welcome, as are those that concern geochemical mapping and those that comprise case histories. Given the many links between exploration and environmental geochemistry, the journal encourages the exchange of concepts and data; in particular, to differentiate various sources of elements. GEEA publishes research articles; discussion papers; book reviews; editorial content and thematic sets.
