Hanza region is located in the southern part of Urumieh–Dokhtar Metallogenic belt in southeastern Iran. This region includes six known porphyry copper deposits and it is considered as an ore- bearing region from geochemical point of view. The aim of this research is to examine effective processing techniques in the analysis of stream sediment geochemical datasets and ASTER satellite images. The...

maharlu saline lake is located in the sw of iran. to assess the environmental pollution of thelake, the total concentrations of as, cr, co, cu, cd, pb, zn, ni, fe, and mn were determined in the surfacesediments and water of the lake. as and cr were not detected in the water samples, however, the meanconcentrations of other dissolved metals in maharlu lake water were 0.28 mg/l for cu, 0.28 μg/l ...

in an attempt to reconstruct the paleoenvironments of deposition for the middle jurassic baghamshah formation, samples collected from six outcrop sections along the shotori swell were subjected to detailed geochemical analyses. bulk geochemical and biological marker data indicate a logical trend of the variation of organic input, salinity, and oxicity within baghamshah paleoenvironments across ...

Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...

[1] Although most Central American magmas have a typical arc geochemical signature, magmas in southern Central America (central Costa Rica and Panama) have isotopic and trace element compositions with an ocean island basalt (OIB) affinity, similar to the Galapagos-OIB lavas (e.g., Ba/La < 40, La/Yb > 10, Pb/Pb > 18.8). Our new data for Costa Rica suggest that this signature, unusual for a conve...

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...

Introduction: The current knowledge of the geological history of Venus can be interpreted in terms of the history of the geochemical environments on this planet. One can distinguish two parts of the geologic history of Venus: the later part, for which we have morphological records supplemented by geochemical measurements on the surface and in the atmosphere, and the earlier part, for which ther...

This thesis evaluates the utility of a geochemical technique for the investigation of paiaeoenvironmental change in south west England. The method, EDMA (Energy Dispersive X-ray Micro Analysis), is a rapid, non-destructive analysis tool, capable of detecting a large range of geochemical elements. This research examines the most appropriate method of sample preparation for organic soils and peat...
