Sažetak
This study provides new insights into the distribution of rare earth elements (REE) in a range of chlorite from hydrothermally altered mafic rocks from the Dinarides. Low-medium grade metamorphic conditions to include zeolite, prehnite-pumpellyite, and greenschist facies assemblages reveal unique geochemical signatures of chlorite, thus reflecting the interaction between hydrothermal fluids and host rock lithologies. A diverse set of chlorite have been identified and may comply with characteristic rare earth element signatures that can be categorized and defined by specific geochemical and textural parameters. Fe-rich chlorite may contain significant enrichments in REE in contrast to Mg- rich members, particularly with the LREE. Additionally, numerous textural varieties such as amygdales and pseudomorphic chlorite have been identified and may also reflect their own distinct trace element signatures. This research will (a) use stable isotope geothermometric methods to constrain the formation conditions of a variety of chlorite, (b) make estimates on redox state using the enrichment/depletion of Ce and Eu, and (c) make inferences concerning the sources of REE which provide the initial rare earth element budget of the fluids, all to provide further support for the rare earth elemental codependency on the conditions in which they themselves and the fluid have been subjected to.
