Analytical electron microscopy of a hydrated interplanetary dust particleProperties of a hydrated interplanetary dust particle (IDP), Ames-Dec86-11, were investigated using TEM and analytical electron microscopy. The particle was found to have mineralogy and chondritic composition indicating an absence of direct kinship with known carbonaceous chondrites. The available data on the Ames-Dec86-11 suggest that at least one aqueous alteration event took place in this hydrated IDP, during which fine-grained material, possibly glass, was transformed to smectite. This event appears to be unique to hydrated IDPs.
