Soluble Organic Compounds in the Tagish Lake Meteorite
Introduction: The Tagish Lake meteorite is an ungrouped carbonaceous chondrite that represents some of the most primitive material available for study. It contains a high amount of organic carbon (~2.6 wt%); however, only 2% of this is soluble in polar solvents [1]. As with other organic-rich meteorites, terrestrial contamination is a concern. Many potential sources of terrestrial contamination...
متن کاملSulfur-rich Carbonaceous Nanoglobules in the Tagish Lake Meteorite
Introduction: Understanding the distribution, chemistry, and structure of C in carbonaceous chondrites (CC) is fundamental to revealing information on early solar chemical evolution. The Tagish Lake CC has generated much interest partly because of its pristine nature and high C content [1,2,3]. Unique to the Tagish Lake CC are hollow carbonaceous nanoglobules [4]. These particles are morphologi...
متن کاملThe organic content of the Tagish Lake meteorite.
The Tagish Lake meteorite fell last year on a frozen lake in Canada and may provide the most pristine material of its kind. Analyses have now shown this carbonaceous chondrite to contain a suite of soluble organic compounds (approximately 100 parts per million) that includes mono- and dicarboxylic acids, dicarboximides, pyridine carboxylic acids, a sulfonic acid, and both aliphatic and aromatic...

متن کاملIn-situ Heating Decrease Kinetics of Aliphatic Hydrocarbons in Tagish Lake Meteorite by Micro-ftir
Introduction: Carbonaceous chondrites are known to contain up to 3wt.% C, the major part of which corresponds to a macromolecular organic fraction [1]. Chondritic organic matter is based on small aromatic units, cross-linked by short aliphatic chains rather than large clusters of polyaromatic structures [2]. Two main characteristic features of those organics measured by FTIR are (1) an equivale...
