A scanning electron microscope study of a fine‐grained, pink Ca‐rich inclusion from the Allende meteorite has revealed strong evidence for direct condensation of its constituent minerals from a vapor. This observation extends to the alkali‐bearing phases in addition to the Ca‐, Al‐ silicates and suggests that the feldspathoids as well as the refractory silicates are solar nebular condensates.
