Abstract Stable isotope composition of ?2H and ?18O was investigated in the water resources Shwan sub-Basin northeast Iraq. The study objects conceived possible factors that affect stable isotopes’ precipitation additionally to achieve information concerning recharge processes estimate groundwater sources. In this study, four samples were collected at area for 2020–2021 hydrological year. Thirt...

For more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. However, in developing countries like Iran the application of such techniques is in its infancy. The first research inIran was carried out in 1975 to identify the source of saline groundwaters in south Iran, and the first national conference o...

Volcanic (lava tube) caves at Lava Beds National Monument (N. CA, USA) provide a valuable terrestrial analog for volcanic on Mars and the Moon. Terrestrial host diverse microbial life, liquid water, variety of secondary mineral deposits (speleothems) with morphologies chemical compositions. Speleothems may preserve records past present life signatures paleoenvironmental changes in caves. Distin...

Water temperatures of hot springs close to tectonic fault zones often show some variations before earthquakes, and analyses earthquake precursors in have significant referential meaning for monitoring forecasting. This study measured the concentration major ions water from Hongshuilantang Hot Spring 2017 2020. The ion composition was classified by hydrochemistry into HCO 3 ·SO 4 -Na chemical ty...

Stable isotopes (Deuterium and Oxygen-18) have a broad application in many of water related sciences. Precipitation is the most important input to the water cycle which shows considrable spatial and temporal variability in its isotope content. To study the precipitation isotope content, 51 samples from August 2015 to July 2016 have been collected mainly on a monthly basis with few events based ...

Abstract. We present speleothem fluid inclusion ?18Of and ?2Hf values from Larga Cave, Puerto Rico, that cover the interval between 46.2 15.3 ka on millennial scale, including Last Glacial Maximum (LGM) several stadial interstadial cycles. The data set can be divided in two main clusters of stable isotope compositions water with respect to global meteoric line (GMWL), which coincide strong vari...

Moisture conditions are important ecological factors limiting plant growth in karst areas. In areas, because bedrock exposure and permeability significant soils dispersed—without spatial continuity—and shallow, the water storage required for uptake rock fissures as well shallow is very limited, therefore, an factor influencing growth. order to discover sources of used by plants zone ecosystem s...
