| Popis: | In the northern district of Hesse sandstones which have very high lithium contents (400–1000 ppm) occur in the basement of the Kupferschiefer. The lithium values are related to cookeite but not to quartz as it was stated in the literature. The cookeite contains up to 1,6% Li, while quartz has only 80 ppm Li and less. Geochemical criteria lead to the conclusion that the lithium enrichment must have taken place primaryly during the sedimentation. Most likely lithium biotites were deposited along with quartz and feldspar. The cookeite was formed later by diagnetic alteration of these biotites. |
