Data are presented from stepwise heating experiments and total extractions on five meteorites: Kapoeta, Fayetteville, Holman Island, Cee Vee and Pultusk. These data reveal the presence of four isotopically distinct trapped neon components. A comparison of trapped neon with trapped helium and argon in bulk analyses indicates the existence of correlated helium, neon and argon isotopic structures. The major trapped components in gas-rich meteorites and the LFB (lunar fines and breccia) are found to have the following isotopic compositions Component B 3.9 ± 0.3 12.52 ± 0.18 0.0335 ± 0.0015 5.37 ± 0.12 Component C 4.1 ± 1.0 10.6 ± 0.3 0.042 ± 0.003 4.1 ± 0.8 Component D 1.5 ± 1.0 14.5 ± 1.0 - 6 ± 1 Component B is attributed primarily to direct implantation of rare gas ions by the present day solar wind. Component C is identified with directly implanted low energy (1-10 Mev/n) solar flare rare gases. Component D is associated with rare gas ions implanted in meteoritic material by the primitive, pre-main sequence, solar wind. A fourth component, observed only in Kapoeta and the LFB, is tentatively attributed to parent body `atmospheric' ions implanted in surface material by a solar wind induced electric field.
