Lianbinite is a new mineral, approved in 2023 and to date (September 2025) reported only from the type locality.

Localities

At the type locality, the Western end, Pusch Ridge, Pima County, Arizona, USA, lianbinite occurs as colourless bladed or prismatic crystals, associated with baryte, fluorite, glecklerite, jarosite, jimkrieghite, quartz and rasmussenite. Lianbinite is colourless, transparent with a white streak and vitreous lustre. It is brittle and has a Mohs hardness of 1–1½ (AM 110.9.1481–1487).
Lianbinite is a secondary mineral believed to have formed through the evaporation process of fluids containing glycolic acid, C₂H₄O₃ and (NH₄)⁺ derived from plants or bacterial activities (Mindat).
