The Insoluble Carbonaceous Material of Cm Chondrites as Possible Source of Discrete Organics during the Asteroidal Aqueous Phase

چکیده
The larger portion of the organic carbon in carbonaceous chondrites (CC) is present as a complex and heterogeneous macromolecular material that is insoluble in acids and most solvents (IOM). So far, it has been analyzed only as a whole by microcopy (TEM) and spectroscopy (IR, NMR, EPR), which have offered and overview of its chemical nature, bonding, and functional group composition (e. g., [1] and Fig 2). Chemical or pyrolytic decomposition has also been used in combination with GC-MS to identify individual compounds released by these processes [2 and ref.s therein]. Their value in the recognition of the original IOM structure resides in the ability to properly interpret the decomposition pathways for any given process.

Soluble Organic Species Released from the Insoluble Carbonaceous Material of a Pristine Cr2 Meteorite
Introduction: Soluble organic compounds are known to be abundant in CM carbonaceous chondrites (CC), where they comprise a complex and diverse suite of both water-, and solventextractable molecular species [1]. The soluble organic composition of the Renazzo-type meteorites, known only recently through the studies of a few CR2 finds from Antarctica, was shown to differ from that of CMs in the ov...
متن کاملThe Role of Microchemical Environments in the Alteration of Cm Carbonaceous Chondrites
Introduction: Aqueous fluids have left their fingerprint on almost all the known chondrite groups and attest to the fact that water was a widespread agent of change in the early solar system [1,2]. The interaction of liquid or gaseous water with the primary products of nebular processes caused significant textural, mineralogical, compositional and isotopic changes that are often very complex to...
متن کاملOrganic Constituents in Carbonaceous Chondrites; Evidence for Preservation of Pristine Particles of Mixed Origins
Introduction: Carbonaceous chondrites are primitive meteorites that have sampled the oldest conden-sates of the solar system. They have accreted components of various origins: CAIs (also known as refrac-tory inclusions), chondrules, ice, noble gases and or-ganics. Radioactive decay of short lived radionucleides quickly heated these parent bodies and drove thermal metamorphism and aqueous altera...

Introduction: Hydrated minerals and organic matter (OM) found in chondrites are the remnants of primordial reservoirs of volatile elements present in the protoplanetary disk 4.6 billion years ago. Among primitive chondrites, CM-type carbonaceous chondrites constitute a well-identified chemical group that presents a wide range of hydrothermal alteration degrees on their asteroidal parent body an...
