  • Clay mineral

    Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces . Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.

  • Clays: Mineral information, data and localities.

    A group of minerals, common in soils (see also the rock clay ). Many doubtful clays are probably impure kaolinite. [Clark, 1993

    However, mining activities on large scale are confined mainly to a few minerals

    The name bementite, sometimes used for the former mineral, has priority for a Mn-rich mineral that belongs to the friedelite group of minerals and is not a layer silicate (Kato, 1963). The name rectorite has priority over allevardite for a regular 1: 1 interstratification of paragonite-smectite (Brown and Weir, 1963).

    The clay minerals in GT are part of a sequence of remotely detected hydrous and hydroxylated minerals exposed on Aeolis Mons. These clays are overlain by rocks enriched in sulfates and iron oxides ( 19 , 20 ), a sequence that is widely observed on Mars and is thought to have formed during exhaustion of the planet’s near-surface liquid water ( 3 , 21 ).
