A Review of Progress in Microbeam Lu-Hf Isotopic Analysis on Minerals
BACKGROUND Mircobeam Lu-Hf isotopic analysis on minerals provides an important means to understand the microscopic process of magmatic activity and metamorphic reaction and to trace provenance of sediment, which greatly promotes the development of ...

Meteorite zircon constraints on the bulk Lu-Hf isotope composition and early differentiation of the Earth. [PDF]
Significance The radioactive decay of lutetium-176 to hafnium-176 has been used to study Earth’s crust−mantle differentiation that is the primary agent of the chemical and thermal evolution of the silicate Earth. Yet the data interpretation requires a well-defined hafnium isotope growth curve of the bulk Earth, which is notoriously difficult ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Recovery of 177Lu from Irradiated HfO2 Targets for Nuclear Medicine Purposes
A new method of production of one of the most widely used isotopes in nuclear medicine, 177Lu, with high chemical purity was developed; this method includes irradiation of the HfO2 target with bremsstrahlung photons.

Research Progress in situ Hf Isotopic Analysis of Oxide-type U-bearing Accessory Minerals
BACKGROUND In recent years, the in situ Hf isotopic determination method of zircon has been widely used in isotopic geochemistry, and has become an important method to explore the genesis of rocks, the source of ore-forming materials and the evolution of

Temporal and Hf isotope geochemical evolution of southern Finnish Lapland from 2.77 Ga to 1.76 Ga [PDF]
The southern Finnish Lapland area in the central part of the Fennoscandian shield is a geologically complex zone comprising several Archean blocks and Paleoproterozoic supracrustal belts all of which are intruded by voluminous Paleoproterozoic granites ...

Constraints on Martian Chronology from Meteorites
Martian meteorites provide the only direct constraints on the timing of Martian accretion, core formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope chronometers have been applied to a wide variety of Martian samples,
