The major, minor and trace element chemistry of chlorite were evaluated as a tool for mineral exploration in the propylitic environment porphyry ore deposits. Chlorite from eighty propylitically altered samples, located up to 5 km Batu Hijau Cu–Au deposit Indonesia, was analyzed using electron microprobe laser ablation inductively-coupled plasma mass spectrometry. results show that variety elements, including K, Li, Mg, Ca, Sr, Ba, Ti, V, Mn, Co, Ni, Zn Pb, are probably incorporated lattice...
Faced with ongoing depletion of near-surface ore deposits, geologists are increasingly required to explore for deep deposits or those lying beneath surface cover. The result is increased drilling costs and a need maximize the value drill hole samples collected. Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis pyrite one tool that showing promise in exploration. Since trace element content approximates composition fluid from which it precipitated...
Abstract The giant, high-grade Resolution porphyry Cu-Mo deposit in the Superior district of Arizona is hosted Proterozoic and Paleozoic basement an overlying Cretaceous volcaniclastic breccia sandstone package. has a central domain potassic alteration that extends more than 1 km outboard ore zone, overlapping with propylitic halo characterized by epidote, chlorite, pyrite particularly well developed Laramide rocks dolerite sills. assemblages were overprinted upper parts intense phyllic...
Hydraulic actuation is the most widely used alternative to electric motors for legged robots and manipulators. It often selected its high power density, robustness high-bandwidth control performance that allows implementation of force/impedance control. Force crucial are in contact with environment, since it enables active impedance whole body can lead a better known unknown environments. This paper presents hydraulic Integrated Smart Actuator (ISA) developed by Moog collaboration IIT, as...
Abstract The mineral chemistry of epidote and chlorite from the propylitic halo at El Teniente, in samples collected distances up to 6.6 km deposit center, was determined by microprobe laser ablation-inductively coupled plasma-mass spectrometry. Results show that both minerals systematically incorporated a range trace elements define much larger footprint system than is easily recognized using conventional means such as whole-rock geochemistry. Apart Fe Mg chlorite, there no significant...

In the past decade, significant research efforts have been devoted to mineral chemistry studies assist porphyry exploration. These activities can be divided into two major fields of research: (1) indicator minerals (PIMs), which are used identify presence of, or potential for, porphyry-style mineralization based on magmatic such as zircon, plagioclase and apatite, resistate hydrothermal magnetite; (2) vectoring fertility tools (PVFTs), use chemical compositions epidote, chlorite alunite...
Abstract Tourmaline is a structurally and chemically complex hydrous borosilicate mineral that displays significant compositional variability in both major trace elements. Its occurrence wide variety of ore-forming systems makes tourmaline powerful provenance indicator because it can record the temporal spatial evolution hydrothermal fluid compositions provide key information regarding metal fertility exploration vectoring within system. In this study, tourmaline-bearing rocks were sampled...
The decomposition of H2S by a short-lived radio-frequency pulse has been investigated. main primary dissociation is → 2H + S and the most important subsequent reactions are: H SH H2(4); HS H2+ (6); 2SH (8); 2S M S2+ (10); 2S2+ S4+ (11). Computer simulation gives as best rate constant values: k4= 5.0 × 108 mol–1 dm3 s–1; k6= 1.3 1010 k8= 1.9 k10= 4.3 1012 mol–2 dm6 k11= 8 s–1. CH3SH (CH3)2S was also studied with particular reference to processes.
The Mesozoic deposits in the Central Andes, especially represented by dominant iron oxide copper-gold (IOCG) mineralization southern Peru and northern Chile coastal IOCG belt, has emerged as one of major exploration targets Andes last two decades. These mainly formed during Middle-Late Jurassic Early Cretaceous. Cu-rich are located Cretaceous which is also main Phanerozoic example this type ore deposit. Andean lie a linear array interconnected continental margin rift basins that record phase...
The newly discovered Jiyuan Cu–Ag–(Pb–Zn–Au) deposit is located in the southern section of eastern Tianshan orogenic belt, Xinjiang, northwestern China. It first documented large Aqikekuduke Ag–Cu–Au belt orogen. Detailed field observations, parageneses, and fluid inclusion studies suggest an epithermal ore genesis for main Cu–Ag mineralization, accompanied by a complicated hydrothermal alteration history most likely associated with multi-stage tectonic evolution Tianshan. bodies are along...
Abstract The Collahuasi district of northern Chile hosts several late Eocene-early Oligocene world-class porphyry Cu-Mo deposits, including Rosario, Ujina, and Quebrada Blanca associated high-sulfidation epithermal mineralization at La Grande. Mineralization is hosted by intermediate to felsic intrusive volcanic rocks the upper Paleozoic Lower Triassic Group, which experienced lower greenschist facies regional metamorphism prior mineralization. Extensive hydrothermal alteration zones...
Mining and exploration companies routinely use four-acid digestion (4AD), inductively coupled plasma, atomic emission spectra/mass spectrometry methods from commercial assay laboratories for analysing drill rock samples lithogeochemical assessment resource reporting. This method is also known to exhibit lower recovery of elements hosted by resistate minerals. To assess the impact recoveries on interpretation, a suite commonly used analysis (high-field-strength Zr, Hf, Nb, Ta, Ti Eu...
We recently presented a new mechanism for primordial black hole formation during first-order phase transition in the early Universe, which relies on build-up of particles are predominantly reflected from advancing bubble wall. In this companion paper we provide details supporting numerical calculations. After describing general mechanism, discuss criteria that need to be satisfied form. then set out Boltzmann equation describes evolution relevant space distribution function, carefully our...
The Mount Read Volcanics (MRV) of western Tasmania is a belt Middle to Late Cambrian submarine volcanics and volcaniclastics one the major base precious metal provinces within Australia. Exploration success in MRV has been decline recent years due variety challenges including intensely altered rocks with complex stratigraphy lithofacies variation, lack accessible outcrop. As result, local regional mapping often restricted Group-level stratigraphy, rendering geological ineffective for...
The Nellie Tonalite forms a discontinuous 20 km elongate northwest-trending felsic intrusion at the far-western end of Western Zone Lamboo Province, in Wunaamin Miliwundi Orogen, Australia. This is poorly understood with previous interpretations assigning it to ca 1860 Ma Paperbark Supersuite. We present first geochronological results for Tonalite, which have weighted mean laser ablation, inductively coupled plasma, mass spectrometry (LA-ICP-MS) U–Pb zircon age 1794 ± 4 Ma. date coincident...
