Fig. 2From: Original composition and formation process of slab-derived deep brine from Kashio mineral spring in central JapanRelationships between pH and Cl concentration and between water temperature and Cl in water samples from the two wells of the Kashio mineral spring. The pH was constant over the measurement period whereas the Cl concentration varied. Water temperature showed a weak negative correlation with Cl variation, aside from two anomalous values obtained from Kashio B samples (KNK-16-M006 and -M008)Back to article page
