Comparative Re-Os systematics of chondrites: Implications regarding early solar system processes
A suite of 47 carbonaceous, enstatite, and ordinary chondrites are examined for Re-Os isotopic systematics. There are significant differences in the Re/Os and Os/Os ratios of carbonaceous chondrites compared with ordinary and enstatite chondrites. The average Re/Os for carbonaceous chondrites is 0.392 0.015 (excluding the CK chondrite, Karoonda), compared with 0.422 0.025 and 0.421 0.013 for or...
متن کاملCalcium isotopic compositions of chondrites
We report mass-dependent and mass-independent Ca isotopic variations in nine chondrites from three groups: carbonaceous, ordinary and enstatite chondrites. There is about 0.25‰ per amu, i.e., 1‰ in Ca/Ca, variation in chondrites: carbonaceous chondrites have the lightest Ca isotopes, enstatite chondrites have modeled bulk Earth like Ca isotopes, and ordinary chondrites are in between. The corre...
متن کاملThulium anomalies and rare earth element patterns in meteorites and Earth: Nebular fractionation and the nugget effect
This study reports the bulk rare earth element (REEs, La–Lu) compositions of 41 chondrites, including 32 falls and 9 finds from carbonaceous (CI, CM, CO and CV), enstatite (EH and EL) and ordinary (H, L and LL) groups, as well as 2 enstatite achondrites (aubrite). The measurements were done in dynamic mode using multi-collector inductively coupled plasma mass spectrometers (MC-ICPMS), allowing ...
متن کاملOxygen isotopes in calcium^aluminum-rich inclusions from enstatite chondrites: new evidence for a single CAI source in the solar nebula
Calcium^aluminum-rich inclusions (CAIs) from enstatite chondrites have large 16O excesses, similar to CAIs in carbonaceous and ordinary chondrites, and are also similar in morphology, mineralogy and Al^Mg isotopic systematics. These similarities provide new evidence that most CAIs might have formed in a single, restricted nebular locale and were then distributed unevenly throughout the various ...
متن کاملDifferences in mean densities of the terrestrial planets have long been interpreted as inferring differences in the major elem
Major element fractionation among chondrites has been discussed for decades as ratios relative to Si or Mg. Expressing ratios relative to Fe leads to a new relationship admitting the possibility that ordinary chondrite meteorites are derived from two components: one is a relatively undifferentiated, primitive component, oxidized like the CI or C1 chondrites; the other is a somewhat differentiat...
