Quantitative Analysis of Geological Samples- X-Calibur
Abstract Quantitative and qualitative analysis of geological samples (rocks and river sediments) was performed on Xenemetrix EDXRF Benchtop Spectrometer System, model X-Calibur Objective: Perform XRF measurements on certified geological reference materials to build calibration curves for the major oxides (Na2O, MgO, SiO2, Al2O3, SiO2, P2O5, SO3, K2O, CaO, TiO2, MnO and Fe2O3) and for trace ...

Optimal solute transport in heterogeneous aquifer: coupled inverse modelling
Characterisation of transmissivity heterogeneity is critical for groundwater flow and solute transport. The heterogeneity of transmissivity is studied through variogram-based techniques. Conventionally, the parameters in variogram are obtained by fitting measurements to a theoretical variogram. However, conditioning to the sampled geological variables neglects the effects of observed ...

Map of the Month - May
Welcome to Edinburgh Instruments monthly blog celebrating our work in Raman Microscopy, Photoluminescence, and Fluorescence Lifetime Imaging. Every month we will highlight our pick for Map of the Month to show how our spectrometers can be used to reveal all the hidden secrets in your samples. May Gemstones are pieces of mineral crystal cut and polished for use in the gem and jewellery industry. ...

Combining Raman microscopy with scanning electron microscopy (SEM) to study inorganic and mineral samples at the Geological Institute of Romania, Bucharest
The Geological Institute of Romania, located in Bucharest, was founded in 1906. It is famous for its museum which hosts a collection of more than 80,000 samples of rocks, fossils and minerals from all over Romania. Oana-Claudia Barbu and Daniel Bîrgăoanu are both PhD students and research assistants in the electron microscopy laboratory, known as MICROCOSMOS, where they study ...

Using a Ternary Diagram or Ternary Plot in Geochemistry?
A ternary diagram, also known as a ternary plot or triangle plot, is a three-variable graph used to represent the composition of a mixture or system composed of three components. These ternary diagrams are typically displayed as equilateral triangles, with each apex representing one of the three components. The interior of the triangle represents all possible combinations of these components, and ...

Integration of Subsurface Data Management and GIS to Facilitate Model Calibration
Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...

History of Metrohm IC - Part 6
Even though combustion ion chromatography (CIC) is regarded as an up-and-coming sample preparation and analysis technique, the basic process behind CIC has already existed for many years. This blog post introduces the history of this technique, the working principle, and some applications for CIC.\r\n"}}">Even though combustion ion chromatography (CIC) is regarded as an up-and-coming sample ...

Measurement of a Doubly Substituted Methane Isotopologue, 13CH3D
ABSTRACT: Methane is an important energy resource and significant long-lived greenhouse gas. Carbon and hydrogen isotope ratios have been used to better constrain the sources of methane but interpretations based on these two parameters alone can often be inconclusive. The precise measurement of a doubly substituted methane isotopologue, 13CH3D, is expected to add a critical new dimension to ...

Fold geometry model of Coyote hills segment of Puente hills blind-thrust system applied to interpretation of long-term water level data
Recent work by others along the Coyote Hills segment of the Puente Hills blind-thrust system has imaged the near-surface structural features generated by activity of that intrabasin fault. Published shallow seismic profiles near the south flank of the Coyote Hills indicate the blindthrust system is expressed by south-facing folding of Quaternary terrestrial sediments underlying the hills. ...

The impact of an open waste disposal site on soil and groundwater pollution
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...
