Vendian Hydrogeochemistry of the Siberian Platform

Russian Geology and Geophysics, 2021
Abstract —The Vendian deposits of the Siberian Platform are represented by four regional horizons (from bottom to top): Nepa, Vilyuchan, Tira, and Danilovka. The TDS of brines in the Nepa and Vilyuchan horizons varies from 170.3 to 470.1 g/L, and the TDS in the overlying Tira and Danilovka horizons, from 84.6 to 583.1 g/L.

Hydrogeochemistry of the Catskill Mountains of New York

Annals of the New York Academy of Sciences, 2013
Major ion chemistry of Catskill region groundwater is characterized on the basis of 207 analyses compiled from three sources, including a web‐based U.S. Geological Survey database, state agency regulatory compliance data, and sampling of trailside springs performed by the authors.

Hydrogeochemistry and Water Quality

2020
The waters associated with carbonate aquifers are of calcium and/or calcium–magnesium carbonate types, with the ratio r Mg/r Ca increasing with the dolomite content of the rock, possibly exceeding that of the unit. Classic texts to consult on the matter are: Hem [1], Catalan [2], Custodio [3, 4, 5], Appelo and Postma in Chap. 2 [1] and Fagundo (in Chap.

Hydrogeochemistry in the Yilgarn Craton

Geochemistry: Exploration, Environment, Analysis, 2001
The hydrogeochemistry of the Yilgarn Craton and its margins has been extensively investigated, with particular emphasis on the chemistry of Au. Four groundwater regions have been delineated based on variations in salinity, acidity and oxidation potential: (1) Northern (N Yilgarn and margins) – Fresh and neutral ...

Hydrogeochemistry of Uranium in the Groundwaters of Serbia

2014
For the present study, 172 groundwater samples (collected from wells and natural springs in Serbia) were analyzed for different chemical parameters including uranium. For each groundwater sample, information was compiled about the basic parameters of its chemical composition. Most of the samples were found to be of the Na – HCO3 and Ca, Mg − HCO3 water

Hydrogeochemistry of the Curnamona and Mundi region

Output Type: Exploring for the Future Extended AbstractShort Abstract: Groundwater geochemistry is an important and often under-appreciated medium to understand geology below surface and is a valuable tool as part of a regional mineral exploration program. This study presents an assessment of hydrogeochemical results from the Curnamona and Mundi region

Hydrogeochemistry of the Chiang Mai Basin, northern Thailand

Journal of Asian Earth Sciences, 1997
Abstract Chemical composition of groundwater samples collected from 247 boreholes throughout the Chiang Mai Basin was determined in order to describe the background ion concentrations and to identify the major hydrogeochemical processes that control the observed water chemistry.
