Nuclear particle track data in three cores (14211/14210, 15010, and 76001) are presented to illustrate the importance of different modes of accretion at different sites. Track densities of individual grains and quartile track densities as a function of depth are presented for the Apollo 14 core; and although they are characteristic of typical mature soils, they show striking variations with depth. A gradual accumulation of the Apollo 15 core is favored, and the Apollo 17 core is found to be heavily irradiated. With the exception of a sample taken at 27 cm depth, and in contrast with the other sections studied, the whole core 76001 consists of material in which the quartile track density is in excess of 10 to the 8th per sq cm.
