Apatite Chlorine Concentration Measurements by LA-ICP-MS
Kamber, Balz; Chew, David; Stock, Michael (2014)Apatite incorporates variable and significant amounts of halogens (mainly F and Cl) in its crystal structure, which can be used to determine the initial F and Cl concentrations of magmas. The amount of chlorine in the ... -
Combined zinc-lead isotope and trace-metal assessment of recent atmospheric pollution sources recorded in Irish peatlands
Tomlinson, Emma; Kamber, Balz; Rosca, Carolina; Schoenberg, Ronny (2019)Atmospherically-fed Earth surface archives such as ombrotrophic peatlands, lake sediments, and ice consistently show an upward increase in Zn concentrations of hitherto unclear origin. Here, we present a combined stable ... -
An exsolution origin for Archean mantle garnet
Tomlinson, Emma; Kamber, Balz (2017)It is well established that the cratonic subcontinental lithospheric mantle (C-SCLM) represents a residue of extensively melted peridotite. The widespread occurrence of garnet in C-SCLM remains a paradox because experiments ... -
From ocean to mantle: new evidence for U-cycling with implications for the HIMU source and the secular Pb isotope evolution of Earth's mantle
Kamber, Balz; Pettke, Thomas; Kodolányi, János (2018)Of the isotopically distinctive mantle domains, the so-called HIMU (“high-μ”; μ = 238U/204Pb) source is the most extreme, and its genesis continues to be debated. We report very strong U enrichment at unchanged Th ... -
Petrological, mineralogical and geochemical peculiarities of Archaean cratons
Tomlinson, Emma; Kamber, Balz (2019)The most outstanding features of Archaean cratons are their extraordinary thickness and enduring longevity. Seismically, Archaean cratonic fragments are sharply-bounded deep roots of mechanically strong, cold lithospheric ... -
Quantitative data extraction from orthopyroxene trace element maps and its potential to examine the formation of the UG2 unit, bushveld complex
Kamber, Balz (2019)We present a mineral chemical stratigraphy across the UG2 Unit, situated in the Upper Critical Zone of the Bushveld Complex. The magmatic evolution of the rocks hosting this world-class ore deposit for chromium and platinum ... -
Rare Earth Element Determination in Olivine by Laser Ablation-Quadrupole-ICP-MS: An Analytical Strategy and Applications
Kamber, Balz; Tomlinson, Emma (2017)Olivine offers huge, largely untapped, potential for improving our understanding of magmatic and metasomatic processes. In particular, a wealth of information is contained in rare earth element (REE) mass fractions, which ... -
U-Pb LA-ICPMS dating using accessory mineral standards with variable common Pb
Kamber, Balz; Chew, David (2014)Precise and accurate U?Pb LA-ICPMS dating of many U-bearing accessory minerals (e.g. apatite, allanite, titanite and rutile) is often compromised by common Pb. LA-ICPMS dating of these U-bearing accessory phases typically ...
