Unusual neon isotopic composition in Neoproterozoic sedimentary rocks: Fluorine bearing mineral contribution or trace of an impact event?
2019, Chemical GeologyCitation Excerpt :As such, it preferentially is found in the outer 100 nm of objects and thus recovered in objects with a high surface to volume ratio such as IDP. Bigger objects such as meteorites can also include the Ne-B component if they derive from a regolith, however, they can additionally contain the Ne-A component (e.g. Black, 1972; Pepin, 1967), which has been recorded in pre-solar nano-diamonds (Huss and Lewis, 1994) and is particularly found in carbonaceous chondrites (see review in Moreira, 2013). Those two extraterrestrial signatures are distinct from the one that characterizes the material at the surface of the Earth.
Planetary and pre-solar noble gases in meteorites
2014, Chemie der ErdeCitation Excerpt :The similarity in isotopic composition between Q and ureilite neon strengthens the case for a close relationship between the two components as already evident in the elemental abundance pattern (Fig. 2; Section 2.2). Neon in presolar diamonds (P3, HL, P6) dominates the neon inventory of primitive meteorites (Fig. 6; see Section 3), and formerly identified components Ne-A (Pepin, 1967), or Ne-A1 and Ne-A2 (e.g., Alaerts et al., 1980; Swindle, 1988) can be related to these newly identified primary components: A1 corresponds to P3, A2 to HL+P6, and A is probably a mixture of all three plus, in addition, contributions from Ne-G and/or Ne-R. Since the P6 contribution is difficult to resolve, the value listed for HL in Table 3 and shown in Fig. 3 probably contains some P6 contribution.
