Rare Earth, Major, and Trace Element Geochemistry of Surface and Geothermal Waters from the Taupo Vsurface water, and sediments/ precipitates, indicate that temperature has a strong effect on REE fractionation in the sampled fluids. Eu- and Ce-anomalies (Eu/Eu*, Ce/Ce*) are visible in several samples and are related both to the inheritance of Eu and Ce abundances from geologic host materials and

,Geochemistry of Rare Earth Elements in Groundwaters from a Rhyolite Aquifer, Central México,itic volcanic rocks similar to those of the Cuatralba Ignimbrite aquifer. Shale-normalized Yb/Nd ratios of La Muralla groundwaters range from 1.85 to 6.55, with a mean (± standard deviation) of 4.2 ± 1.2. Rare earth element concentrations for La Muralla groundwaters are normalized to the average REE

Rare earth element concentrations generally decrease along the groundwater flow path in the Carrizo sand aquifer, whereas in the Upper Floridan aquifer, the Nd concentrations increase first and then slightly decrease, Gd concentrations are erratic, and E
