Rare earth elements of the Arima-type spring waters in Kii Peninsula: implications for upwelling process

Abstract

The Kii peninsula is one of the place where the specific brine is upwelling, in addition to Arima hot spring which is the type locality of Arima-type brine. In this study, we have investigated spring waters in the Kii peninsula in order to constrain the origin and upwelling process, and discuss the relationship between Arima-type brine and geological setting, based on the comparison with volcanic rocks.
