Generation of Geochemical Exploration Targets from Regional Stream Sediment Data Using Principal Component and Factor Ana

نویسندگان

چکیده

A regional-scale stream sediment geochemical sampling was carried out with an averagesampling density of one sample per nine square-kilometre in Kiteto District, Manyara Region.A total 358 samples were collected and analysed for major traceelements by X-ray fluorescence (XRF) fire assay atomic absorption spectrometry(AAS) finish methods. In this study, Factor Principal Component Multivariate (FPCM)analyses have been used to the data delineate potential mineralizationzones plotting correlated factors as anomaly maps. Four that accountfor 73.7% variance established.Factor 1: Ni–Ba–Co–Cu–Sr which possibly defines underlying metamorphosed graniticunits some contribution from mafic ultramafic rocks. 2: Cr–Zn–Mn whichdefines crustal forming elements reflecting 3 entails Rb Pbprobably attributed granitic lithology. 4 is arsenic, a chalcophileelement affinity sulfide phases. The FPCM analyses successfully indelineating target areas gold, nickel copper exploration study area.
 Keywords: Stream sediment; principal component; factor analysis; targets;Kibaya-Kiteto, Manyara.

Application of continuous restricted Boltzmann machine to detect multivariate anomalies from stream sediment geochemical data, Korit, East of Iran

Anomaly separation using stream sediment geochemical data has an essential role in regional exploration. Many different techniques have been proposed to distinguish anomalous from study area. In this research, a continuous restricted Boltzmann machine (CRBM), which is a generative stochastic artificial neural network, was used to recognize the mineral potential area in Korit 1:100000 sheet, loc...

Using stream sediment data to determine geochemical anomalies by statistical analysis and fractal modeling in Tafrash Region, Central Iran

Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...

Factor analysis applied to regional geochemical data: problems and possibilities

A large regional geochemical data set of C-horizon podzol samples from a 188,000 km area in the European Arctic, analysed for more than 50 elements, was used to test the influence of different variants of factor analysis on the results extracted. Due to the nature of regional geochemical data (neither normal nor log-normal, strongly skewed, often multimodal data distributions), the simplest met...
