CHONDRITE GROUPS<br />

Weisberg et al. (2006)<br />

• Different <strong>degree</strong>s <strong>of</strong> <strong>aqueous</strong> <strong>alteration</strong><br />

and metamorphism are found<br />

• The CCs can be classified according <strong>the</strong><br />

estimated T required to produce <strong>the</strong><br />

petrographic types (Dotto et al., 2005)<br />

• The highest hydrated groups<br />

correspond to <strong>the</strong> carbonaceous<br />

chondrites, particularly: CMs, CRs,<br />

and CIs<br />

• At <strong>the</strong> Institute <strong>of</strong> Space Sciences<br />

(CSIC-IEEC) we work in <strong>the</strong> lab<br />

focusing on <strong>the</strong> role <strong>of</strong> <strong>aqueous</strong><br />

<strong>alteration</strong> on primitive chondrites and<br />

performing remote studies <strong>of</strong> comets<br />

• Particularly, <strong>the</strong> reflectance spectra are<br />

taken in <strong>the</strong> UPC Center for Research in<br />

NanoEngineering<br />
