Experiment
NIR reflectance spectrum (i=0°, e=30°) of bulk CM, CR, CI and ungrouped chondrites under vacuum at room temperature before and after a heating cycle
Layer
- Name
- powder of bulk MAC88100 CM chondrite after temperature cycle
- Type of layer

- Thickness
- 1.0 $\pm$ 0.1 $mm$
- Mass
- 40.0 $\pm$ 5.0 $g$
- Texture
- loose granular

- Comments
- sample, initially at 297K, was heated at 373 K, 523K, and again at 297K. For each thermal step, the sample was kept at the desired temperature during 30 minutes for the sample to thermalize, then the reflectance acquisition started for 1 hour
