TLDR
Primordial trapped planetary noble gases and solar isotopic ratios in separated meteoritic minerals from Orgueil carbonaceous chondrite were obtained in this article, where they were extracted from meteoritic materials.About:

Abundances of the elements: Meteoritic and solar
Edward Anders,Nicolas Grevesse +1 more
TL;DR: In this article, new abundance tables have been compiled for C1 chondrites and the solar photosphere and corona, based on a critical review of the literature to mid-1988.

Solar-system abundances of the elements
Edward Anders,Mitsuru Ebihara +1 more
TL;DR: In this paper, the Ogueil Cl meteorite and all previous Cl chondrite analyses were employed to develop a new solar system abundance table, including the standard deviation and number of analyses for each element.
Journal ArticleDOI
Early chemical history of the solar system
TL;DR: In this article, the sequence of condensation of mineral phases from a cooling nebula of solar composition has been calculated by using equilibrium thermodynamics, and theoretical models suggest that the chemistry and mineralogy of Ca-Al-rich inclusions in C2 and C3 chondrites were established during condensation at temperatures above 1300 K.

C3He in volatile fluxes from the solid Earth: implications for carbon geodynamics
Bernard Marty,Albert Jambon +1 more
TL;DR: In this paper, the C3He ratios of the relevant reservoirs are considered and it is shown that this ratio is unfractionated during magma outgassing, a best estimate being 2 × 109.

Rare gas systematics: formation of the atmosphere, evolution and structure of the Earth's mantle
TL;DR: In this paper, an Earth model based on four reservoirs: atmosphere, continental crust, upper mantle and lower mantle was explored, where mass balance equations, the concept of mean age of outgassing and the systematic use of all of the rare gases involving both absolute amount and isotopic composition were employed.

Origin, age, and composition of meteorites.
Edward Anders,Edward Anders +1 more
TL;DR: Signer and Suess as discussed by the authors brought together and evaluated all significant evidence on the origin of meteorites, and showed that the absence of a Widmanstatten pattern in meteorites with > 16% Ni cannot be attributed to high pressures, but to supercooling or an unusually fast cooling rate for these meteorites.

Chemical fractionations in meteorites—II. Abundance patterns and their interpretation
John W Larimer,Edward Anders +1 more
TL;DR: In this article, the abundance of thirty-one volatile elements in meteorites is reviewed, and it is shown that carbonaceous chondrites are a mixture of two types of material: a low-temperature fraction (matrix) that retained most of its volatiles and a high temperature fraction (chondrules, metal grains) that lost them.
Journal ArticleDOI
Noble gases in carbonaceous chondrites
TL;DR: Carbonaceous chondrites noble gases measurement by mass spectroscopy, discussing compositional trends and origins as mentioned in this paper, discussed compositional trend and origins of chondrite noble gases.

On the chemical evolution of the carbonaceous chondrites
E. R. Dufresne,Edward Anders +1 more
TL;DR: In this article, it was shown that an internal atmosphere, sealed by an ice layer from a low pressure exterior, could have persisted for at least several million years if the parent body were at an asteroidal distance from the sun.
