Abstract

TANAKA et al.1 have suggested that there must be barium-rich micro-components in the Allende meteorite. We have confirmed this prediction by discovery of barium-rich particulates (see ref. 2). Figure 1 shows diffuse distribution of Ba-rich particles as well as their clusters; each of apparent particles seems to be composed of finer particulates probably of submicron size. Tanaka and Okumura2 showed that the Ba-rich spots are also high in content of titanium. Figure 2 shows the areal overlapping of the distribution of Ba with that of Ti. Relatively sparse dots for Ti are due to shorter scanning time than for Ba.
