Quartz is one of the most abundant minerals. Used in a variety materials, it preserves geological history and reflects alteration conditions. Data were collected (>2400 data points) from more than 40 ore deposits to understand its internal texture geochemistry. Cathodoluminescence imaging technique for examining quartz that may reveal information about crystal’s origin evolution. The dominan...

Human activity has become a significant geomorphic force in modern times, resulting in unprecedented movements of material around Earth. An essential constituent of this material movement, the major industrial metals aluminium, copper, iron, and zinc in the human-built environment are mapped globally at 1-km nominal resolution for the year 2000 and compared with the locations of present-day in-...

Diamond-reinforced metal matrix composites (DMMC) prepared by cold spray are emerging materials simultaneously featuring outstanding thermal conductivity and wear resistance. In our paper, their mechanical fatigue properties relevant to perspective engineering applications were investigated using miniature bending specimens. Two different diamond mass concentrations (20 50%) embedded in two mat...

The results of the study content, spatial distribution and transformation Fe, Mn, Pb, Zn Cu in system benthal deposits Belaya River are presented. obtained were compared with background concentrations metals, which allow us to estimate anthropogenic component. It has been established that discharges from industries cause increased metals certain areas basin.

Trace element (TE) analysis of pyrite via LA-ICP-MS can be used to reconstruct the conditions formation in complex mineral systems. The Carpentaria province northern Australia is host some world’s highest value Zn-Pb (+Ag, Cu) deposits. genesis many these deposits controversial, with competing models single-vs. multi-stage ore formation. In this study, data paragenetically constrained from Geor...

Abstract There is increasing demand for critical metals (e.g., W-Sn, Li-Be-Nb-Ta, and rare earth elements [REEs]) to sustain the transition green energy, yet it unclear what controls formation of such metal ore systems. Here, we focus on South China, which well endowed with metals, imaged its crustal architecture by zircon Hf isotopic mapping using 1096 isotope data sets 1457 samples Mesozoic g...

neyshabour turquoise mine is located in northwest of neyshabour, southern quchan volcanic belt. eocene andesite and dacite forming as lava and pyroclastic rocks cover most of the area. subvolcanic diorite to syenite porphyry (granitoids of magnetite series) intruded the volcanic rocks. both volcanic and subvolcanic rocks are highly altered. four types of alteration are recognized including: sil...

Geochemistry of surface hyporheic stream sediments, multivariate statistics and GIS database proved successful tools for assessing toxic element contamination in East Attica region. The objectives of this study were to assess the degree of contamination and to describe the surface hyporheic stream sediment geochemical variations in relation to geology, lithology and anthropogenic activities of ...
