WebBiotite is an easily weathered sheet silicate that can undergo a number of transformations from unweathered biotite to altered biotite to 2:1 clays (e.g., vermiculite and smectite) to 1:1 clays (e.g., kaolinite and halloysite), depending on the intensity of the weathering environment (Ahn & Peacor, 1987; Buss et al., 2008; Dong et al., 1998 ... WebJul 1, 2024 · Weathering of biotite in subtropical Tongcheng synchronously produced randomly interstratified B/V and halloysite in the mid-lower portions of the weathering regolith, and the mixed-layer B/V partially transformed to discrete vermiculite in the topsoil due to advanced weathering. B/V clays persist throughout the weathering profile with a ...
