Amino acid compositions in heated carbonaceous chondrites and their compound-specific nitrogen isotopic ratios
A novel method has been developed for compound-specific nitrogen isotope compositions with an achiral column which was previously shown to offer high precision for nitrogen isotopic analysis. We applied the method to determine the amino acid contents and stable nitrogen isotopic compositions of individual amino acids from the thermally metamorphosed (above 500 °C) Antarctic carbonaceous chondri...
متن کاملPristine Pre-accretionary Signatures in Cm Chondrite Silicates: a Common Parent-body with the Co Chondrites?
Introduction: The Mighei-like carbonaceous (CM) chondrites are one of the most abundant and aqueously altered group of carbonaceous chondrites [1–4]. The organic molecules present and the effects of aqueous alteration have been extensively studied in the CM chondrites [e.g., 1,3,5]. As many CM chondrites are extensively aqueously altered, the compositions and formation histories of their anhydr...
متن کاملOne-pot synthesis of amino acid precursors with insoluble organic matter in planetesimals with aqueous activity
The exogenous delivery of organic molecules could have played an important role in the emergence of life on the early Earth. Carbonaceous chondrites are known to contain indigenous amino acids as well as various organic compounds and complex macromolecular materials, such as the so-called insoluble organic matter (IOM), but the origins of the organic matter are still subject to debate. We repor...
متن کاملCharacterising the CI and CI-like carbonaceous chondrites using thermogravimetric analysis and infrared spectroscopy
The CI and CI-like chondrites provide a record of aqueous alteration in the early solar system. However, the CI-like chondrites differ in having also experienced a late stage period of thermal metamorphism. In order to constrain the nature and extent of the aqueous and thermal alteration, we have investigated the bulk mineralogy and abundance of H2O in the CI and CI-like chondrites using thermo...
متن کاملMetastable equilibria among dicarboxylic acids and the oxidation state during aqueous alteration on the CM2 chondrite parent body
Linear saturated dicarboxylic acids are present in carbonaceous chondrite samples at concentrations that suggest aqueous alteration under conditions of metastable equilibrium. In this study, previously published values of dicarboxylic acid concentrations measured in Murchison, Yamato-791198, and Tagish Lake carbonaceous chondrites are converted to aqueous activities during aqueous alteration as...
