147Sm-143Nd and 146Sm-142Nd systems were studied in nineteen 3.32-4.02 Ga zircon grains from Jack Hills metaconglomerate, 12 of which were previously analyzed...

The use of radioactive decay of 176Lu to 176Hf to study the evolution of the Earth requires a precise and accurate value for the 176Lu decay constant. Recent...
We have studied the 147Sm-143Nd and 146Sm-142Nd isotopic systems in phosphate fractions and chondrules from six ordinary chondrites and one carbonaceous...
We present the results of a comparative study of several geochronometer minerals (baddeleyite, zircon, apatite, phlogopite and tetraferriphlogopite) and...
Two different groups of values for the 176Lu decay constant have been determined by recent high-precision experiments. The 176Lu values of 1.86-1.87 × 10-11...
Analytical errors calculated for individual spot 206Pb/238U measurements of zircon analyzed using high mass resolution secondary ion mass spectrometry...
A geochronology study using U-Pb isotope dilution TIMS analyses of zircon has been conducted to determine the ages of volcanic-associated massive sulfide (VMS)...
U-Th-Pb isotopic data are reported for mineral fractions, individual chondrules and fractions of chondrule fragments from the equilibrated ordinary chondrite...
Chondrules, which are the major constituent of chondritic meteorites, are believed to have formed during brief, localized, repetitive melting of dust (probably...
