  • USGS OFR01-041: Mixed-layer clays

    Mixed-layer clays can form by weathering involving the removal or uptake of cations (e.g. K), hydrothermal alteration, or removal of hydroxide interlayers, and, in some cases, may represent an intermediate stage in the formation of swelling minerals from non-swelling minerals or visa versa (MacEwan and Ruiz-Amil, 1975; Sawhney, 1989).

    Mixed-layer I/V clays are characterized by basal XRD peaks between 1.0 nm and 1.4 nm for air-dried, Mg-saturated, and glycol-solvated samples, whereas the 001 spacing of the vermiculite layers in mixed-layered I/V would change from 1.4 nm to 1.0 nm on heating, indicating the loss of water and hydroxy-cations from their interlayers.
