A Metasomatized Lithospheric Mantle Control on the Metallogenic Signature of Post-Subduction Magmatism Nature Communications (2019)
Ore deposits are loci on Earth where energy and mass flux are greatly enhanced and focussed, acting as magnifying lenses into metal transport, fractionation and concentration mechanisms through the lithosphere. Here we show that the ...
Geochronology and Geochemistry of the Intrusive Suite associated with the Khatsavch Porphyry Cu-Au (Mo) Deposit, South Mongolia Ore Geology Reviews (2019)
The Khatsavch porphyry Cu-Au (Mo) deposit is located in the Gurvansayhan island arc terrane of South Mongolia, approximately 45 km southwest of the Oyu Tolgoi Cu-Au district, one of the largest porphyry-type Cu-Au deposits in ...
Transition Metals in Komatiitic Olivine: Proxies for Mantle Composition, Redox Conditions, and Sulfide Mineralization Potential American Mineralogist (2019)
We present the results of a comprehensive study on the concentrations of first-row transition elements (FRTE: Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn), as well as Ga and Ge, in liquidus ...
The Role of the Polochic Fault as Part of the North American and Caribbean Plate Boundary: Insights from the Infill of the Lake Izabal Basin Basin Research (2019)
The Lake Izabal Basin in Guatemala is a major pull-apart basin along the sinistral Polochic Fault, which is part of the North American and Caribbean plate boundary. The basin infill contains information about the tectonic ...
Ruthenium in Chromite as Indicator for Magmatic Sulfide Liquid Equilibration in Mafic-Ultramafic Systems Ore Geology Reviews (2018)
The platinum-group element ruthenium (Ru) is an important petrogenetic tracer of Earth's accretion history, core-mantle interaction, mantle evolution and the exploration for magmatic sulfide deposits. However, its geochemical behavior in mafic-ultramafic systems is still not ...
Post-Collisional Alkaline Magmatism as Gateway for Metal and Sulfur Enrichment of the Continental Lower Crust Geochimica et Cosmochimica Acta (2018)
Mafic and ultramafic magmas that intrude into the lower crust can preserve evidence for metal and sulfur transfer from the lithospheric mantle into the lower continental crust. Here we focus on a series of ultramafic, ...
Improved Precision and Accuracy of Quantification of Rare Earth Element Abundances via Medium-Resolution LA-ICP-MS Journal of the American Society for Mass Spectrometry (2017)
Laser ablation ICP-MS enables streamlined, high-sensitivity measurements of rare earth element (REE) abundances in geological materials. However, many REE isotope mass stations are plagued by isobaric interferences, particularly from diatomic oxides and argides. In this ...
The Variability of Ruthenium in Chromite from Chassignite and Olivine-Phyric Shergottite Meteorites: New Insights into the Behavior of PGE and Sulfur in Martian Magmatic Systems Meteoritics and Planetary Science (2017)
The Martian meteorites comprise mantle-derived mafic to ultramafic rocks that formed in shallow intrusions and/or lava flows. This study reports the first in situ platinum-group element data on chromite and ulvöspinel from a series of ...
Sulfur and Metal Fertilization of the Lower Continental Crust Lithos (2016)
Mantle-derived melts and metasomatic fluids are considered to be important in the transport and distribution of trace elements in the subcontinental lithospheric mantle. However, the mechanisms that facilitate sulfur and metal transfer from the upper ...
Genesis and Tectonic Implications of Podiform Chromitites in the Metamorphosed Ultramafic Massif of Dobromirtsi (Bulgaria) Gondwana Research (2015)
Podiform chromitites occur in the meta-dunite horizon of the Dobromirtsi ultramafic massif, in the Central Rhodope metamorphic core complex (southern Bulgaria). Although these were deformed and metamorphosed together with their host rocks several chromite cores ...
The Capacity of Hydrous Fluids to Transport and Fractionate Incompatible Elements and Metals within the Earth's Mantle Geochemistry, Geophysics, Geosystems (2014)
Both silicate melts and aqueous fluids are thought to play critical roles in the chemical differentiation of the Earth's crust and mantle. Yet their relative effects are poorly constrained. We have addressed this issue by ...
Ruthenium Variation in Chromite from Komatiites and Komatiitic Basalts -- A Potential Mineralogical Indicator for Nickel Sulfide Mineralization Economic Geology (2013)
More than 390 chromite grains from komatiites and komatiitic basalts from the Yilgarn craton of Western Australia and the Finnish part of the Fennoscandian Shield were analyzed using in situ laser ablation inductively coupled plasma ...
The Oxidized Ores of the Main Sulphide Zone, Great Dyke, Zimbabwe: Turning Resources into Minable Reserves-Mineralogy Is the Key Journal of the Southern African Institute of Mining and Metallurgy (2013)
The Great Dyke of Zimbabwe constitutes the world's second largest reserve of platinum group elements (PGE) after the Bushveld Complex in neighbouring South Africa. Within the Great Dyke, economic concentrations of PGE are restricted to ...
