In 1998, there were many volcanic earthquakes recorded at Iwate volcano, Japan. Although an eruption was anticipated, it never occurred. Fumarolic gases were sampled at the volcano on six occasions du...
Long time-series of chemical and isotopic compositions of Vesuvius fumaroles were acquired in the framework of the volcanic surveillance in the 1998-2010 period. These allow the identification of proc...
The Terme Sibarite and nearby thermomineral water discharges have Ca–SO4 to Ca–SO4–HCO3 composition, near neutral pH value of 6.9 to 7.6, outlet temperatures of 16° to 25.5°C, variable redox potentia...
A hydrochemical and isotopic study was carried out on spring waters of the Damour River Basin and groundwaters from wells in the coastal Mediterranean plain in Lebanon. The aim of this study was to de...
Rainwater samples were collected from six stations at coastal and highland regions in Lebanon and analyzed for the major species Ca2+, K+, Na+, Mg2+, NO3-, NH4+, pH, Cl-, and SO42-. Absolute concentra...
Abstract: Mineralogical (XRD), morphological (transmission electron microscopy), chemical (major, rare-earth elements, and scanning-transmission electron microscopy), and isotope (Sr, O, H) measuremen...
