International audience Introduction: Secondary phases in hydrated Antarctic micrometeorites (AMMs) will show an oxygen isotopic signature from their likely formation by aque-ous processes, in either a comet or asteroid parent body. Asteroidal water may be distinguishable from cometary water in its o...
