Christensen J.N.; Halliday A.N. (1996)Rb-Sr ages of melt inclusions in quartz have the potential to provide a unique and illuminating record of the differentiation and accumulation history of silicic magmas. Here we report the first Sr and Nd isotopic measurements ...
-
Fehr M.A.; Rehkamper M.; Halliday A.N.; Schonbachler M.; Hattendorf B.; Gunther D. (2006)Tellurium isotope data acquired by multiple-collector inductively coupled plasma-mass spectrometry (MC-ICPMS) are presented for sequential acid leachates of the carbonaceous chondrites Orgueil, Murchison, and Allende. ...

Fehr M.A.; Rehkämper M.; Halliday A.N.; Wiechert U.; Hattendorf B.; Günther D.; Ono S.; Eigenbrode J.L.; Rumble III D. (2005)New precise Te isotope data acquired by multiple collector inductively coupled plasma mass spectrometry (MC-ICPMS) are presented for selected extraterrestrial and terrestrial materials. Bulk samples of carbonaceous, ordinary ...
-
Halliday A.N. (2000)The former decay of 182Hf to 182W (T1/2=9 Myr) has resulted in variations in W isotope composition that reflect early solar system time-integrated Hf/W ratios. The bulk silicate Earth (BSE) has non-chondritic Hf/W because ...
-
Porcelli D.; Halliday A.N. (2001)The core has often been suggested as a source for He presently found in the mantle. If the core served as the long-term storage reservoir for He in ocean island basalts with distinctively high 3He/4He ratios, then the ...

Godfrey L.V.; Sangrey W.F.; White W.M.; Lee D.C.; Halliday A.N.; Salters V.J.M.; Hein J.R. (1997)We present Hf and Pb isotopic data, and chemical compositions of the outermost layers of marine ferromanganese deposits of different types (hydrogenous and hydrothermal) with a worldwide distribution. The Hf isotopic ...
-
Leya I.; Wieler R.; Halliday A.N. (2003)Variations in the atomic abundances of 53Cr, 92Zr, 98Ru, 99Ru, and 182W in meteorites and lunar samples relative to terrestrial values may imply the early decay of radioactive 53Mn, 92Nb, 98Tc, 99Tc and 182Hf, respectively. ...

Snyder G.A.; Taylor L.A.; Beard B.L.; Sobolev V.N.; Crozaz G.; Halliday A.N.; Sobolev N.V. (1997)Owing to the association with diamonds, eclogite xenoliths have received disproportionate attention given their low abundance in kimberlites. Several hypotheses have been advanced for the origin of eclogite xenoliths, from ...
-
Rehkamper M.; Halliday A.N. (1999)The precision of Tl isotopic measurements by thermal ionization mass spectrometry (TIMS) is severely limited by the fact that Tl possesses only two naturally occurring isotopes, such that there is no invariant isotope ratio ...
-
Teagle D.A.H.; Alt J.C.; Halliday A.N. (1998)A unique record of the chemical evolution of seawater during hydrothermal recharge into oceanic crust is preserved by anhydrite from the volcanic sequences and sheeted dike complex in ODP Hole 504B. Chemical and isotopic ...
-
Halliday A.N.; Lee D.C. (1999)The rates of accretion and core formation of the Earth and other inner solar system objects can be effectively studied using the newly developed 182Hf-182W chronometer. This approach offers far more leverage than any other ...
-
Schonbachler M.; Lee D.C.; Rehkamper M.; Halliday A.N.; Fehr M.A.; Hattendorf B.; Gunther D. (2003)Isotopic anomalies in Mo and Zr have recently been reported for bulk chondrites and iron meteorites and have been interpreted in terms of a primordial nucleosynthetic heterogeneity in the solar nebula. We report precise ...
