Abstract

Hydrothermal fluids were collected from five hydrothermal fields around the Southern Mariana Trough backarc spreading center for chemical and isotopic analyses. Yamanaka site was interpreted as inactive, so we present results from Snail, Archaean, Pika and Urashima sites. The slightly low pH and negative alkalinity suggests a little bit input of magmatic volatiles, supported by high CO2 concentrations. Consequently low pH would lead to the hydrothermal fluids rich in Fe compared to the MOR hydrothermal fluids.
