Geochemical Evaluation of Drinking Water in Arak City, Iran
This paper presents results of an assessment of dominant hydro-geochemical processes controlling groundwater chemical composition, using an integrated application of cluster analysis and factor analysis. The area is located in south of saline playa and in Arak city. Cluster analysis classified samples into two main clusters according to their dominant chemical composition: cluster A (dominant c...
متن کاملGeochemical Evaluation of the Lagos Lagoon Sediments and Water
The Lagos lagoon is a depository of last resort for over 70% of the surface runoffs, drainage channels and important rivers flowing from interior Nigeria to the Atlantic Ocean. The surrounding densely populated and industrialized areas often result in the introduction of potential harmful materials into the Lagoon. This work is aimed at providing reference data for the quality assessment of the...
متن کاملExperimental and geochemical studies of terrestrial and lunar magmatic processes
Experimental and geochemical studies were performed to understand the formation of certain terrestrial and lunar igneous rocks. Chapter one is a study of convergent margin magmatism at Medicine Lake Volcano, California. The petrogenesis of a suite of variably porphyritic, high-alumina lavas was inferred from field relations, hydrous melting experiments and geochemical modeling. I conclude that ...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Geochemical Transactions
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...
