Sažetak
This study offers new findings about how trace elements, and rare earth elements (REE) in particular, are distributed in various types of chlorite found abundantly in hydrothermally altered non-ophiolite effusive and tuffaceous rocks placed within the volcano-sedimentary Triassic record of Adria Microplate in the Dinaride region. By studying the geochemical signatures of chlorite formed under low-medium grade metamorphic conditions, including zeolite, prehnite–pumpellyite, and greenschist facies assemblages, this study has identified a diverse set of chlorite that exhibits unique REE signatures that can be categorized and defined by specific geochemical and textural parameters. The research shows that Fe-rich chlorite may have significant enrichments in REE, particularly in the LREE, compared to Mg-rich members. In addition, different textural varieties of chlorite, such as amygdales and pseudomorphic chlorite, have their own distinct trace element signatures. The study uses stable isotope geothermometric methods to determine the formation conditions of various chlorite samples, estimate the redox state using the enrichment/depletion of Ce and Eu, and make inferences about the sources of REE that provide the initial rare earth element budget of the fluids, all of which having brought further evidence on the dependence of REE chlorite abundances on the characteristics of hydrothermal fluids and chlorite geochemistry and mineralogy.
