What is Rare Earth Element Patterns in a Rapidly Changing Karst Environment about?

Samples of surface water, groundwater and rocks were collected along the Louros River karst system in Greece to study the evolution of the chemical composition of groundwater. It was found that the hydrochemistry is closely related to the lithology of the host rocks. Emphasis was placed on the study of REEs due to the presence of phosphate-rich rocks in the area. A distinctive feature that was also taken into account was the high velocities of surface and groundwater in this rapidly changing karst environment. The carbonate formations of the Ionian Zone determine the hydrogeology of the catchment, particularly the Senonian, Vigla and Pantokrator limestones, through which groundwater mainly moves at relatively high velocities, play a key role. From the northernmost areas at the upper part of the catchment to the southernmost areas at the river's mouth, a multitude of springs, along the river, mark the main base level, above which a common aquifer is formed on either riverbed, hydraulically and locally connecting those geological formations. The chemical composition of the water is mainly controlled by the dissolution of calcite, dolomite and gypsum, with Ca–HCO3 being the dominant w
