Extended Data Fig. 10: Mineral phases observed by SEM-EDX in precipitates of typical abiotic morphology and ‘biomorphs’.
From: Hyperdiverse archaea near life limits at the polyextreme geothermal Dallol area

Biomorphs correspond to rounded-shaped crystalline morphs resembling cell structures (cocci, rods) and compatible with cellular sizes. Observed dominant phases are highlighted in bold.
