Sri Lanka provides an ideal opportunity for the study of the effect of geology on human health. The vast majority of the people of Sri Lanka still live in rural areas within areas termed geochemical provinces. Very broadly, one could say that a geochemical province has characteristic chemical composition in soil, water stream sediments and rocks, enabling their delineation from others. The chem...

BACKGROUND Reactive-transport simulation is a tool that is being used to estimate long-term trapping of CO2, and wellbore and cap rock integrity for geologic CO2 storage. We reacted end member components of a heterolithic sandstone and shale unit that forms the upper section of the In Salah Gas Project carbon storage reservoir in Krechba, Algeria with supercritical CO2, brine, and with/without ...

Together with generalized self-similarity and the fractal spectrum, local singularity analysis has been introduced as one part of the new 3S principle and technique for mineral resource assessment based on multifractal modeling, which has been demonstrated to be useful for anomaly delineation. Local singularity is used in this paper to characterize the property of multifractal distribution patt...

In this research work, the frequency domain (FD) of surface geochemical data was analyzed to decompose the complex geochemical patterns related to different depths of the mineral deposit. In order to predict the variation in mineralization in the depth and identify the deep geochemical anomalies and blind mineralization using the surface geochemical data for the Dalli Cu-Au porphyry deposit, a ...

the gold mineralization in kurdistan province of iran was classified as shear zone gold type by some of the researchers. in the current study, the geochemical samples collected from the secondary environment, stream sediments, at the sw of saqquez area were used to investigate the geochemical characteristics of the gold mineralized zones in this environment. the multi-variant statistical analys...

Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...

Biosolids-borne trace elements may be released to the environment when biosolids are used as fertilizers in farm land. Trace element leachate concentrations from biosolids are known to be limited by both organic and inorganic sorbent surfaces; this experimental evidence has not been previously verified with geochemical modeling of sorption reactions. In this study, pH-dependent leaching experim...

Both geophysical and geochemical techniques contribute to our understanding of the complex nature of the Earth’s mantle, but the two sources of information provide very different viewpoints. Most geophysical evidence provides an instantaneous snapshot of current structure, whilst geochemical evidence has much more information on age. Further, geophysical probes are naturally integrative since t...

BACKGROUND Proteins of various compositions are required by organisms inhabiting different environments. The energetic demands for protein formation are a function of the compositions of proteins as well as geochemical variables including temperature, pressure, oxygen fugacity and pH. The purpose of this study was to explore the dependence of metastable equilibrium states of protein systems on ...
