Spectroscopic studies have shown, however, evidence of hydrated minerals and silicates, which indicate rather a stony surface composition.

Thus previous reports of hydrated minerals and organic compounds on the surface of Lutetia has been disproven.

Scientists are excited about finding hydrated minerals such as sulfates and clays on Mars because they are usually formed in the presence of water.

Any ice on the surface would have gradually sublimated, leaving behind various hydrated minerals like clays and carbonates.

However, torbernite, like other hydrated minerals, can easily suffer from loss of water molecules.

Light-toned rocks on Mars have been associated with hydrated minerals like sulfates.

Places that contain clays and/or other hydrated minerals would be good places to look for evidence of life.

This concentration could indicate water present as remnant ice or in hydrated minerals.

Wave patterns would be analyzed for deposits of hydrated minerals.

Hydrogen is present as water (HO) ice and in hydrated minerals.
