Table 1

Sub-surface structure for different materials and irradiation sources.

	npFe⁰	Vesicles	Amorphization	t (nm)
OL – H⁺	No	Yes	Partial	200
OL – laser	Yes	No	Full	300
OPX – H⁺	No	Yes	Partial	150
OPX – laser	No	Yes	Full	400–2500

Notes. OL stands for olivine, OPX for pyroxene, npFe⁰ for nanophase Fe particles, and t for thickness of the altered layer. The individual columns state whether we identified the object in our samples or not.
