Geochronology Isotope Geosciences Gas hydrate Geochemical Reference Samples Geochemical Atlas (1:200,000) North Kanto area Geochemistry of the Earth's Crust The Geochemistry Department does basic geochemical research on the behavior and distribution of major and trace elements and isotopes in rocks and minerals including extraterrestrial material, and organic and gaseous components in sedimentary rocks and groundwater. The studies of radiometric dating and geochemical reference samples conducted in this department are indispensable for many geological researches. Useful data for environmental and exploration work are provided through the applied geochemical research on the abundance and behavior of elements, isotopes and organic compounds in soils, rocks and minerals. Analytical Methods GSJ develops analytical methods of determining the chemical and isotopic composition of rocks, minerals and other natural materials. They include Atomic Absorption Spectrometry (AAS), X-ray Fluorescence Spectrometry (XRF), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), ICP-Mass Spectrometry (ICP-MS), Instrumental Neutron Activation Analysis (INAA), Thermal Ionization Mass Spectrometry (TIMS) and Secondary Ion Mass Spectrometry (SIMS).

53. Geochemistry UU geochemistry Main page of the geochemistry group in Utrecht University Geochemie. http://www.geo.uu.nl/Research/Geochemistry/

Geochemical research at Utrecht University emphasizes the study of processes taking place in environments near the Earth's surface, in particular, soils, sediments, aquifers, estuaries, and the ocean. These environments are characterized by the presence of water and are linked to one another via the hydrological cycle. In addition to being a transport agent, solvent and chemical reactant, water is indispensable for life. The biogeochemical functioning of Earth surface environments is increasingly affected by human activity. The environmental changes due to mankind occur at the local, regional and global scale. An important task of geochemical research is to characterize these changes and to predict the responses of natural systems to anthropogenic perturbations. The study of past environmental changes provides important constraints on these predictions. Hence, geochemists at Utrecht investigate both modern and ancient environments. Most current research activities at the Department are interdisciplinary and rely on active collaborations with, among others, oceanographers, microbiologists, environmental chemists, and hydrologists.

54. Acid Mine Drainage University of Waterloo research into groundwater geochemistry and remediation of acid mine wastes. http://www.science.uwaterloo.ca/research/ggr/MineWasteGeochemistry/AcidMineDrain

Remediation Department of Earth Sciences University of Waterloo Acid Mine Drainage Introduction The oxidation of sulfide minerals and consequent release of acid in tailings impoundments can last for decades to centuries. The interaction of the low-pH, metals and sulfate contaminated water with tailings and aquifer minerals initiates a sequence of pH-buffering reactions. This increase in pH is often accompanied by the precipitation of metal-bearing hydroxide and hydroxysulfate minerals that remove dissolved metals from the moving water. Research in our group has focused on the mechanisms and consequences of aqueous geochemical and mineralogical changes that occur within and below sulfide tailings impoundments. The research typically involves field and laboratory investigation, enhanced by groundwater flow, geochemical, transport and reactive transport modelling. The research has been collaborative with major companies in the Canadian mining industry, including Agnico Eagle, Falconbridge, INCO, Noranda and Placer Dome. Research assistance has also been provided from NSERC (Natural Sciences and Engineering Research Council of Canada)

Geochemistry From Wikipedia, the free encyclopedia. The field of geochemistry involves study of the chemical composition of the Earth and other planets , chemical processes and reactions that govern the composition of rocks and soils , and the cycles of matter and energy that transport the Earth's chemical components in time and space, and their interaction with the hydrosphere and the atmosphere. The most important fields of geochemistry are: Isotope geochemistry : Determination of the relative and absolute concentrations of the elements and their isotopes in the earth and on earth´s surface. Examination of the distribution and movements of elements in different parts of the earth (crust, mantle, hydrosphere etc.) and in minerals with the goal to determine the underlying legalities of distribution and movement. Cosmochemistry : Analysis of the distribution of elements and their isotopes in the cosmos Organic geochemistry : A study of the role of processes and compounds that are derived from living or once-living organisms. Applications to Environmental and Hydrological studies.
