Hello Frank,
Yes, solar implanted gases were detected and evaluated. This is
summarized in the main text, p 1585 (see below) and further detailed
in the supplementary text "Materials & Methods" where figures S1 to
S36 can be seen, in particular Fig S27 (20Ne/22Ne versus 21Ne/22Ne
plots).
Here is part of the related § of the main text:
..."SM is a regolith breccia. Like all CM chondrites (26), SM contains
Ne from solar wind implantation in a surface regolith (fig. S27).
Unlike most other CM chondrites, the brecciated nature of that
regolith is evident: SM2, 18, 47, 48, 51, and 54 contain angular to
rounded clasts embedded in a fine-grained comminuted matrix seen
visually (Fig. 2A), by x-ray and backscattered electron mapping (Fig.
2B and fig. S13), and by x-ray and neutron computed tomography (figs.
S28 and S30)"...
Kind regards,
Zelimir

Frank Cressy <fcre...@prodigy.net> a écrit :
The "Science" abstract refers Sutter's Mill meteorite as being a regolith
breccia. I've only read the abstract and several other abstracts,
but I don't
remember any mention of it containing solar implanted gases. I was under the
impression that to be a regolith breccia, there had to be a noble
gas content.
Am I missing something or am I completely wrong. (It hasn't been the first
time)
Thanks,
Frank
