Concurrent Pb–Hf isotope analysis of zircon by laser ablation multi-collector ICP-MS, with implications for the crustal evolution of Greenland and the Himalayas
The in situ Lu–Hf isotope analysis of zircon by laser ablation has emerged as a high-calibre tool for tackling magmatic and crustal evolution. The strength of the approach lies with the ability toExpand

Humpback whale songs: Do they organize males during the breeding season?
Summary Male humpback whales (Megaptera novaeangliae )e mit an ever-changing series of sounds during the breeding season known as song. The purpose of this study was to describe the behaviour andExpand

Multiple metamorphic stages within an eclogite-facies terrane (Sesia Zone, Western Alps) revealed by Th-U-Pb petrochronology
Convergent plate margins typically experience a transition from subduction to collision dynamics as massive continental blocks enter the subduction channel. Studies of high-pressure rocks indicateExpand

Eoarchean to Neoarchean evolution of the Nuvvuagittuq Supracrustal belt: New insights from U-Pb zircon geochronology
The Nuvvuagittuq Supracrustal belt in northern Québec is a rare ∼9 km2 fragment of the Earth's early crust. The belt contains a metamorphosed volcano-sedimentary sequence that is at least EoarcheanExpand

Impact melt sheet zircons and their implications for the Hadean crust
Impacts may have been important mechanisms of crustal redistribution and differentiation, particularly during intense postaccretionary bombardment between 4.5 Ga and 3.9 Ga ago. Evidence of crustalExpand

Allanite U–Th–Pb geochronology by laser ablation ICPMS
Abstract The rare earth element (REE) rich epidote-group mineral allanite has great potential as a geochronometer for a wide range of geological processes. Its utilization has been hampered byExpand

Permian high-temperature metamorphism in the Western Alps (NW Italy)
During the late Palaeozoic, lithospheric thinning in part of the Alpine realm caused high-temperature low-to-medium pressure metamorphism and partial melting in the lower crust. Permian metamorphismExpand

In-situ Pb isotope analysis of Fe–Ni–Cu sulphides by laser ablation multi-collector ICPMS: New insights into ore formation in the Sudbury impact melt sheet
Abstract Laser-ablation (LA) multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) is ideally suited to in situ determination of isotope ratios in sulphide minerals. Using samplesExpand
