Insight into zircon REE oxy-barometers: A lattice strain model perspective
Zircon rare earth element (REE) oxy-barometers have been widely used to calculate magma
oxygen fugacity. However, sometimes confusing results are obtained, such as extremely …

Eocene granitoids of northern Turkey: Polybaric magmatism in an evolving arc–slab window system
Abstract The Eastern Pontides Orogenic Belt offers critical clues on the origin of Early
Cenozoic continental arc magmatism in the Alpine-Himalayan system. Systematic …

New magmatic oxybarometer using trace elements in zircon
RR Loucks, ML Fiorentini, GJ Henríquez - Journal of Petrology, 2020 - academic.oup.com
We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon
Evidence of life on Earth is manifestly preserved in the rock record. However, the microfossil
record only extends to∼ 3.5 billion years (Ga), the chemofossil record arguably to∼ 3.8 Ga …

Qinghu zircon: A working reference for microbeam analysis of U-Pb age and Hf and O isotopes
Zircon is the most useful mineral for studies in U-Pb geochronology and Hf and O isotope
geochemistry. Matrix effect is a major problem of the microbeam techniques such as SIMS …

Collision vs. subduction-related magmatism: two contrasting ways of granite formation and implications for crustal growth
Earth's continental crust is dominantly made of buoyant, felsic igneous material (granitoids),
that was ultimately extracted from the mantle as a result of Earth's differentiation. Since felsic …

Continental and oceanic crust recycling-induced melt–peridotite interactions in the Trans-North China Orogen: U–Pb dating, Hf isotopes and trace elements in zircons …
We present the first finding of continental crust-derived Precambrian zircons in garnet/spinel
pyroxenite veins within mantle xenoliths carried by the Neogene Hannuoba basalt in the …

Reappraisement and refinement of zircon U-Pb isotope and trace element analyses by LA-ICP-MS
A protocol was established for simultaneous measurements of zircon U-Pb ages and trace
elements by LA-ICP-MS at spot sizes of 16–32 μm. This was accomplished by introducing …
