This study used stable hydrogen and oxygen isotopes as natural tracers to investigate their isotopic composition in precipitation, and in shallow and deep groundwater in the Penghu Islands in the Taiwan Strait. We aimed to understand the differences and r... see more

In this study, the effects of surface waters on groundwater aquifers were examinedvia physico-chemical analyses and environmental isotopes. The study was carried outin the Uluova region located 10 km northeast of the city of Elazig (Turkey). Watersamples ... see more

There are at least 30 high temperature systems; eleven active volcanoes, five degassing volcanoes and one caldera volcano controlled by Sumatra Fault Zone over a length of 1700 km. To understand this geothermal field system, some information about geochem... see more

This study combines isotopic (87Sr/86Sr, d18O and d13C) with paleontological data to derive a paleosalinity proxy in order to determine the impact of the Aswan High Dam on Manzala lagoon in Egypt's Nile delta. Analyses were made on 17 invertebrate taxa (m... see more

Al Wusta is a desert area in the Sultanate of Oman which is famous due to the discovery of a number of Martian and Lunar meteorites since the start of the present millennium. According to the Meteoritical Bulletin database, 137 approved Martian meteorites... see more

The past atmospheric CO2 concentrations were reconstructed based on the results of measurements of stable oxygen and carbon isotopic ratios of fossil foraminifer and total organic carbon contained in marine sediment taken from the Okinawa Trough, East Chi... see more

We report the equilibration temperatures derived from the oxygen isotope thermometry of pyroxene-olivine pair from the Dar al Ghani (DaG) 476 (1200 +105/-90 °C) and Sayh al Uhaymir (SaU) 008 (1430 +220/-155 °C) meteorites showing a difference of over 200 ... see more

We examined the oxygen and hydrogen isotopic ratios of surface waters and groundwaters in the catchment of Laguna Lake, Republic of the Philippines, to identify the types of water that combine and control these ratios in the lake water. The oxygen and hyd... see more

Aridity and seasonality of precipitation are characteristics of the highland region in Bolivia. Groundwater becomes an important and safe source of water when surficial bodies are intermittent and affected by natural and anthropogenic contamination. Decad... see more
