The Mars rover Spirit encountered outcrops and regolith composed of opaline silica (amorphous SiO[subscript 2]·nH[subscript 2]O) in an ancient volcanic hydrothermal setting in Gusev crater. An origin via either fumarole-related

The Mars rover Spirit encountered outcrops and regolith composed of opaline silica (amorphous SiO[subscript 2]·nH[subscript 2]O) in an ancient volcanic hydrothermal setting in Gusev crater. An origin via either fumarole-related acid-sulfate leaching or precipitation from hot spring fluids was suggested previously. However, the potential significance of the characteristic nodular and mm-scale digitate opaline silica structures was not recognized.
