Comparative study on humic substances isolated in thermal groundwaters from deep aquifers below 700 m
Pannonian Basin thermal water geothermal energy deep aquifer aquatic humic substances
2012/4/11
Main objectives of this study were to investigate whether humic substances (HS) exist in hot groundwater from deep
basinal aquifers waters and to provide basic knowledge on humic (HA) and fulvic acid...
Hydrochemistry of the groundwaters in the Izu collision zone and its adjacent eastern area, central Japan
Izu collision zone groundwater hydrochemistry formation mechanism
2011/4/12
Chemical and stable isotopic (δD, δ18O, δ34S) compositions of rivers and groundwaters, mineral constituents of rock
samples from wells, and δ34S values of anhydrite in the Izu collision zone and its ...
Stable and noble gas isotopic study of thermal and groundwaters in northwestern Hokkaido, Japan and the occurrence of geopressured fluids
geopressured fluid hydrogen isotope oxygen isotope helium isotope Hokkaido
2010/8/9
Thermal and groundwaters are distributed along the west coast and in the inland region of Northwestern Hokkaido, Japan. The waters in the latter group have relatively high temperatures. Stable (D, O) ...
Groundwaters of Mt. Vulture volcano, southern Italy: Chemistry and sulfur isotope composition of dissolved sulfate
Mt. Vulture volcano water-rock interaction silicate weathering hydrogeochemistry sulfur isotope composition
2010/8/9
We report the chemical composition of groundwaters—including the first data on the sulfur isotopic composition of dissolved sulfate—from the volcanic aquifers of Mt. Vulture, one of the most important...
Acidification of Shallow Groundwaters During the Spring Melt Period
Acidification Shallow Groundwaters Spring Melt Period
2009/10/27
During the spring of 1985 shallow recharge area groundwaters at depths less
than one metre in the Turkey Lakes watershed were observed to undergo short
term (1 to 10 days) pH and alkalinity depressi...
VARIATION OF FLUORIDE IN GROUNDWATERS OF CRYSTALLINE TERRAIN
VARIATION OF FLUORIDE CRYSTALLINE TERRAIN GROUNDWATERS
2009/10/19
Groundwater in shallow aquifers that supply water to dugwells in crystalline terrain of the Visakhapatnam region, Andhra Pradesh, have higher concentrations of flouride (F) than those of borewells fro...
Hydrochemical heterogeneity in an upland catchment：further characterisation of the spatial, temporal and depth variations in soils, streams and groundwaters of the Plynlimon forested catchment, Wales
upland catchment Hydrochemical heterogeneity Wales
2009/5/18
The heterogeneous nature of upland hard-rock catchments in terms of geology, geomorphology, superficial deposits, soil type and land use gives rise to a range of hydrochemical characteristics in strea...
Chemical condition for the appearance of a negative Ce anomaly in stream waters and groundwaters
Ce anomaly iron manganese Rare Earth Element Redox processes dissolved organic carbon
2008/8/10
Nine publications showing REE data in groundwaters and river water were examined to understand the general condition of terrestrial water where a negative Ce anomaly develops. It was found that the ne...
Searching and detecting earthquake geochemical precursors in CO2-rich groundwaters from Galicia, Spain
geochemical earthquakes precursors Galicia Spain
2008/8/10
The northwestern region of the Iberian Peninsula was traditionally considered a seismically stable area. However, the 1995 and 1997 Galicia earthquakes of magnitude 4.6 and 5.3 produced significant da...
