Thermal Metamorphism in the CM Parent Body — Evidence from Weakly Altered CM Chondrites LaPaz (LAP) 04565 and 02333

Abreu N. M. * Crispin K. L.

80th Annual Meeting of the Meteoritical Society 2017 [#6365]


“LAP 04514, LAP 04527, LAP 04565 and LAP 02333 are weakly altered CMs. These meteorites resemble Paris and Y 791198 in terms of presence of Fe-Mg amorphous silicates and nano Fe-sulfides and mild thermal metamorphism comparable to petrologic type <3.1."
