"A rare massive yellowish-green serpentinized dunite, covering a minimum area up to ~50 m2 (...). It contains primary olivine and secondary serpentine (antigorite) and brucite. Other primary minerals like orthopyroxene, clinopyroxene, and aluminum-rich phase (such as garnet, spinel, and plagioclase), frequently appearing in ultramafic rocks, have not been identified. The olivine is essentially pure forsterite, with an Mg# (100 × Mg/(Mg + Fe)) of ~99.6–99.7. (...) The petrogenesis of the jianite is presently unclear." (Wang et al., 2020).
