data mining enables generalization of data of soil to remote areas and which is able to up/down scale of data in wide ranges of level that facilitate the decision-making process of executives. cation exchange capacity (cec) is one of the most important parameters in soil database and shows the ability of a soil to retention of minerals and pollutants. due to low organic matter and specific mine...

This paper describes a repeatability test, comparing conventional X-ray diffraction (XRD) analyses with the technique of quantitative X-ray diffraction (QXRD) as a determinant of mineral abundance. The conjunctive use of both methods allows specific mineral abundances to be matched between scene of crime (SOC) and suspects where soil or substrate mineralogy is similar. In our test, samples from...

Earth scientists are often asked to establish or constrain the likely provenance of very small quantities of earth-related material as part of a forensic investigation. We tested the independent and collective interpretations of four experts with differing analytical skills in the prediction of sample provenance for three samples from different environmental settings. The methods used were X-ra...

Quantum mechanical electronic structure calculations are playing an increasingly useful role in many areas of mineralogy and geochemistry. This review introduces the density functional method for such calculations, gives an overview of the density functionals developed at the University of Minnesota, and summarizes selected applications using these density functionals that are relevant to miner...

Soil specific surface area (SA) reflects the quantity and quality of soil mineral organic fractions. For samples that have similar clay types, content or carbon (OC) contents are good predictors SA. However, magnitude OC contribution to SA for different types is unclear, particularly since varies depending on which method probe molecule used measure it. Consequently, we set out (i) quantify tot...

A preliminary investigation of four soil series of the Pin Gin family of krasnozem soils has confirmed the results of field observation on their history and has pointed to the diverse nature of their origins and weathering processes. The weathering pattern and origin can account for differences in their fertility in

Anomalous soil mineralogy can indicate buried geologic structures and zones of permeability. Hyperspectral data can be used to map these anomalies in geothermal exploration efforts. This paper describes work done at Dixie Valley, Nevada, in this regard. Dixie Valley, which lies in the Great Basin, west-central Nevada, is host to a structurally controlled deep-circulation geothermal system. Cait...

The effects of various organic manure [farm yield manure (FYM), sewage sludge and poultry manure] application on adsorption-desorption of three carbamate pesticides [oxamyl(I);S-Ethyl-Nmethylcarbamoyl)oxy]thioacetimidate (II) and N-Phenyl (ethyl carbamoyl) propyl carbamate (III) on six soil samples of Aligarh district was studied. Addition of organic manure increased soil organic carbon content...
