Finally, the stable isotope ratios of lunar and terrestrial rock are identical, implying a common origin.
When rain falls on terrestrial rock (mountains, etc.) it contains some dissolved carbon dioxide from the surrounding air.
Heazlewoodite is known from few ultramafic intrusions within terrestrial rocks.
Such globules, or chondrules, are not found in terrestrial rocks.

These structures are quite unlike features found on the surface of terrestrial rocks and soil.
It looks like a terrestrial volcanic rock, perhaps a gabbro, but it seems to have been formed by multiple lava flows, over time.
However, its tensile strength is probably considerably lower than terrestrial rock and the asteroid also very porous.
If it were a terrestrial rock it would be classified as a basalt breccia.
The rocks are similar to ancient terrestrial rocks called basaltic komatiites.
