In this study two small, but genetically related iron carbonate deposits Mačje Jame and Vranjski Potok, south west of Busovača (MBSM), located in the pre-Devonian metamorphic complex were investigated in detail. Analyses of the main chemical components, trace elements, REE, isotope composition of C, O, S, 87Sr/86Sr ratio of rhyolite, plot of REE normalized to CI chondrites and a microscopic stu...

the gold mineralization in kurdistan province of iran was classified as shear zone gold type by some of the researchers. in the current study, the geochemical samples collected from the secondary environment, stream sediments, at the sw of saqquez area were used to investigate the geochemical characteristics of the gold mineralized zones in this environment. the multi-variant statistical analys...

The potential environmental impact of historical mining and ore processing on stream sediments water was studied in a small siderite iron deposit with diverse sulfide mineral paragenesis. main aim to characterize solid carriers potentially toxic elements (PTEs) mine waste, understand their fate fluvial systems. General mineralogy (X-ray powder diffraction) individual PTE (scanning electron micr...

Abstract The major-element chemical composition of garnet provides valuable petrogenetic information, particularly in metamorphic rocks. When facing detrital garnet, information about the bulk-rock and mineral paragenesis initial garnet-bearing host-rock is absent. This prevents application thermo-barometric techniques calls for quantitative empirical approaches. Here we present a discriminatio...

This study presents rock slab and thin section reflection mapping, element mapping by Micro-XRF (μ-XRF) analysis, in situ cassiterite U-Pb laser ablation-inductively coupled plasma mass spectrometer (LA-ICP-MS) ages of the Xinlu Sn-Zn deposit, Nanling Sn-W belt, South China. The new results provided constraints on age processes Sn mineralization thus further discussed role Paleo-Pacific plate f...

The objective of the study was to characterize clays Lama depression in Benin. Macroscopic examination hand soundings, dynamic penetration test and stratigraphic correlation water borehole logs, as well scanning electron microscopy (SEM) combined with energy-dispersive X-ray microanalysis (EDX) method were made on compact or stratified clays. large grains are embedded a sintered matrix. texture...
