Fluid and metal sources in the Fäboliden hypozonal orogenic gold deposit, Sweden [PDF]
, 2021 To model the formation of orogenic gold deposits, in a global perspective, it is important to understand the ore-forming conditions not only for deposits hosted in greenschist facies rocks but also in amphibolite facies.

Geofluids, Volume 2017, Issue 1, 2017., 2017 The Liyuan gold deposit is hosted within Archean basement metamorphic rocks and controlled by the NNE‐trending faults in the central North China Craton. The ore‐forming processes can be divided into three stages (early, middle, and late). Three types of primary fluid inclusions (FIs) are identified in the Liyuan, including pure carbonic, carbonic ...

Synthesis of Graphene on Gold [PDF]
, 2011 Here we report chemical vapor deposition of graphene on gold surface at ambient pressure. We studied effects of the growth temperature, pressure and cooling process on the grown graphene layers. The Raman spectroscopy of the samples reveals the essential properties of the graphene grown on gold surface.

Journal of Geological Research, Volume 2014, Issue 1, 2014., 2014 The Qatruyeh iron deposits, located on the eastern border of the NW‐SE trending Sanandaj‐Sirjan metamorphic zone, southwest of Iran, are hosted by a late Proterozoic to early Paleozoic sequence dominated by metamorphosed carbonate rocks. The magnetite ores occurred as layered to massive bodies, with lesser amounts of disseminated magnetite and hematite‐

Известия Томского политехнического университета: Инжиниринг георесурсов, 2017 The relevance of the research is caused by the necessity to correct and elaborate on geological (metallogenical) component of the hydrothermal gold deposits formation theory within the framework of which the conflicting ideas about ore-formation ...

Interaction of Gold Nanoparticles in Barium Titanate Thin Films [PDF]
ACS Nano VOL.3 NO.10 3045-3050 2009, 2010 A novel approach to control the grain size of oxide thin film materials has been investigated. Perovskite BaTiO3 shows interesting grain structures when deposited on gold predeposited, (111)-oriented, singlecrystal SrTiO3 substrates. Solid oxide films grow epitaxially on patterned seed layers and show variations in grain size relative to the films ...

Sulphur isotope geochemistry of black shale-hosted antimony mineralization, Arnsberg, northern Rhenish Massif, Germany [PDF]
, 2003 Vein-type and bedding-concordant mesothermal (180–410 °C) stibnite–sulphosalt mineralization at Arnsberg, NE Rhenish Massif, Germany, is hosted by Carboniferous pyrite-rich black shales and siliceous limestones.

Quantum-continuum simulation of underpotential deposition at electrified metal-solution interfaces [PDF]
, 2017 The underpotential deposition of transition metal ions is a critical step in many electrosynthetic approaches. While underpotential deposition has been intensively studied at the atomic level, first-principles calculations in vacuum can strongly underestimate the stability of underpotentially deposited metals.
