ABSTRACT The study of sediment microfabric is fundamental to the understanding of various sediment properties including shear strength, compressibility, and permeability, evaluating depositional environments and investigating clay diagenesis. A technique is presented which preserves the particle integrity of fine-grained sediments while permitting examination of the same sample using light and electron microscopy techniques. The technique involves drying the sediment sample using a critical point drying apparatus and then impregnating it using low viscosity SPURR epoxy. Standard thin sectioning techniques are used for light microscopy, whereas ultrathin sections are made using a microtome for transmission electron microscopy work. Scanning electron microscopy investigations are performed on samples prior to impregnating.
