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 ... -
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 ... -
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 ...
