Stone-building materials, despite their natural origin, must be tested for the concentration of trace elements necessary to assess impact on environment and humans. In addition basic research determining mineral composition structural textural features, it is important analyze geochemical interactions between material matrix that have a negative surrounding our health. presented study, mineralo...

During Phase 1 of the Weyburn Project (2000-2004), 4D reflection seismic data were used to map CO2 migration within the Midale reservoir, while an extensive fluid sampling program documented the geochemical evolution triggered by CO2-brine-oilmineral interactions. The aim of this task (3b.11) is to exploit these existing seismic and geochemical data sets, augmented by CO2/H2O injection and HC/H...

Effective long-term monitoring of commercial carbon dioxide (CO2) geosequestration sites must involve multiple and integrated measurement, monitoring, and sampling techniques in order to identify and quantify CO2 leakage. Measuring changes in CO2 soil gas concentrations in the shallow sub-surface can be problematic due to naturally variable background levels, water table elevation changes, and ...

Numerical modeling is a critical tool to the U.S. Department of Energy for evaluating the environmental impact of remediation strategies for subsurface legacy waste sites. Unfortunately, the physical and chemical complexity of many sites overwhelms the capabilities of even most state of the art groundwater models. Of particular concern is the representation of highly-heterogeneous stratified ro...

This set of notes will try to set down in one coherent place, a general set of equations for calculating changes of major element, reactive trace element and U-series nuclides in an open system. Given the continuous form of the equations we will also deal with scaling and discrete forms using Semi-Lagrangian advection schemes. The key to these derivations will be using general conservation of m...

Kashmar granitoids of Taknar zone, in north part of Lut block, intruded into volcanic rocks and consist of granites, granodiorites, monzodiorite and gabbrodiorites. They are composed of mainly plagioclase, alkali-feldspar, quartz, amphibole, biotite and pyroxene minerals. Harker diagram variation, including negative correlations CaO, MgO, FeO, TiO2 and V and positive correlations K2O, Rb, Ba, a...
