Geochemistry and oxygen isotope composition of main-group pallasites and olivine-rich clasts in mesosiderites: Implications for the “Great Dunite Shortage” and HED-mesosiderite connection
Evidence from iron meteorites indicates that a large number of differentiated planetesimals formed early in Solar System history. These bodies should have had well-developed olivine-rich mantles and consequentially such materials ought to be abundant both as asteroids and meteorites, which they are not. To investigate this “Great Dunite Shortage” we have undertaken a geochemical and oxygen isot...
متن کاملThe oldest zircons in the solar system
Here we report the occurrence, chemistry, and U-Th-Pb isotopic systematics of three meteoritic zircon assemblages, two from the Vaca Muerta mesosiderite and one from the Simmern H5 chondrite. One of the Vaca Muerta zircons occurs in the mesosiderite proper, the other in a eucritic clast associated with chromite, ilmenite, and tridymite, whereas the Simmern zircon occurs in a chondrule composed ...
متن کاملKr-Kr AGE OF THE VACA MUERTA MESOSIDERITE: ON THEIR PARENT BODY
Introduction: Vaca Muerta is classified as a mesosiderite, a breccia of approximately equal mixture of silicate and metal [1]. The mesosiderite includes several types of igneous pebbles [2], of which various textures suggest collision event(s) between differentiated asteroidal bodies for its formation. The unique textures have been attracting interests to investigate formation mechanisms and hi...
متن کاملNiobium-zirconium chronometry and early solar system development.
Niobium-92 (92Nb) decays to zirconium-92 (92Zr) with a half-life of 36 million years and can be used to place constraints on the site of p-process nucleosynthesis and the timing of early solar system processes. Recent results have suggested that the initial 92Nb/93Nb of the solar system was high (>10(-3)). We report Nb-Zr internal isochrons for the ordinary chondrite Estacado (H6) and a clast o...
متن کاملHf-W chronometry and the accretion and early evolution of asteroids and terrestrial planets
We review the chronology for the accretion and earliest evolution of asteroids and terrestrial planets as obtained by applying Hf-W chronometry to meteoritic and planetary samples. Internal Hf-W isochrons for CAIs and angrites yield an absolute age for CAIs of 4568.6±0.7 Ma, which is ~1.5 Ma older than previously determined from PbPb ages for CAIs. Hafnium-tungsten isochrons for H chondrites co...
