An obsolete term for lepidolite.

Lithiophorite, LiAl₂(Mn⁴⁺₂Mn³⁺)O₆(OH)₆, has a structure that contains alternating sheets of (Al,Li)(OH)₆ octahedra and sheets of (Mn³⁺,Mn⁴⁺)O₆ octahedra. The Al,Li sheet chemistry has an ideal ratio of Al:Li of 1:2, but may vary with charge balance being maintained by the Mn oxidation state. Sheets are held together by hydrogen bonding. Lithiophorite occurs in oxidized zones of Mn ore deposits, acidic soils, and low-temperature hydrothermal environments. Lithiophorite has been identified in nodules from Hawaiian soils.

An obsolete term for trilithionite, lithian muscovite.

An obsolete varietal term for lithian muscovite.

A sectile and compact kaolin clay when wetted, often white to red/pink in color and mottled. When dry, lithomarges are friable.

An obsolete term for a massive, compact, often impure kaolin.

A platy trioctahedral member of the serpentine group. The ideal, end-member formula is: Mg₃Si₂O₅(OH)₄. Typical site substitutions include Al and Fe³⁺ for Si and Mg. The most common form of lizardite is the 1T polytype (space group P31m), followed by the 2H₁ polytype (space group P6₃cm). Lizardite is the most abundant serpentine and forms from the weathering (hydration) of ultramafic rocks, primarily composed of olivine and pyroxene.

A yellow-brownish or brown soil mainly composed of sand (>63 μm size, <52% content), silt (2 - 63 μm size, 28 - 50% content), and clay (<2 μm size, 7 - 27% content). Loam commonly exhibits low carbonate contents, but a high nutrient and water content and hence, loam is an excellent plant substrate. Additionally, loam can be used in the building industry to form bricks.
