IDENTIFICATION OF A GEOCHEMICAL SIGNATURE OF GOLD DEPOSITS IN STREAM SEDIMENT DATA: A MULTIVARIATE STATISTICAL APPROACH
In surficial geochemical exploration, scholars have often depend on simple statistical means or single-element concentration to investigate the relationship between elements in surface media and buried orebodies. In this study, a multivariate data analysis technique was used to explore the geochemistry of surfacestream sediments filling the main course of Wadi Haimur and its creeks. In this study, PCA analysiscombined with ... إقراء المزيد

MULTIDISCIPLINARY STREAM SEDIMENT GEOCHEMICAL EXPLORATION
The data gathering in systematic way, led to the construction of the first stream sediment geochemical maps of Wadi Haimur region, which is part of Wadi Allaqi protected area. In these maps, it is possible to find for each element a set of statistics (descriptive parameters, boxplots, cumulative frequency curves, etc.), maps of spatial distribution, among other information of geochemical ... إقراء المزيد

Application of EDXRF handheld to optimize exploration strategies
Stream sediment chemistry and heavy mineral concentrates (HMC) are basic tools for exploring ore deposits. Fast analytical results are needed to optimize exploration strategies. Using an energy dispersive X-ray fluorescence (EDXRF) handheld fixed on a stage, the analysis could be done in the field providing informative results to optimize the exploration strategy. We investigated in the laboratory the effect of ... إقراء المزيد
