Aliphatic Amines in Antarctic CR2, CM2, and CM1/2 Carbonaceous Chondrites [PDF]

, 2016
Meteoritic water-soluble organic compounds provide a unique record of the processes that occurred during the formation of the solar system and the chemistry preceding the origins of life on Earth. We have investigated the molecular distribution, compound-

Impact-generated Porosity Gradients Controlled Fluid Flow and Aqueous Alteration on the CM Parent Body

The Planetary Science Journal
We investigated the relationship between microporosity, impact deformation, and aqueous alteration in the CM chondrite Murchison using high-resolution (1.86 μ m/voxel) X-ray computed tomography (XCT) combined with a pressurized xenon gas infiltration ...

Evaluating the thermal metamorphism of CM chondrites by using the pyrolytic behavior of carbonaceous macromolecular matter [PDF]

The degrees of thermal metamorphism of 10 CM chondrites and of the Allende CV3 chondrite were evaluated from the viewpoint of “graphitization” of the carbonaceous macromolecular matter by means of flash pyrolysis-gas chromatography (GC).

Forming the Noncarbonaceous Chondrite Parent Bodies in the Presence of the Jupiter Barrier

The Astrophysical Journal
Meteorites can be divided into two groups—noncarbonaceous chondrite like (NC) and carbonaceous chondrite like (CC)—with distinct stable-isotope compositions. Parent bodies of NC and CC meteorites have overlapping formation ages. This suggests they formed
