Varnish minerals were originally reported to be amorphous (Engel and Sharp, 1958), with goethite (Scheffer et al., 1963) and ferric chamosite (Washburn, 1969) as important components. Seminal research conducted with infrared spectroscopy, X-ray diffraction and electron microscopy at the California Institute of Technology revealed that the bulk of rock varnish... [Pg.257]

Under transmission electron microscopy (TEM) observations, goethite consisted of acicular crystals. Gibbsite was mainly in the form of hexagonal plates, but also showed the presence of noncrystalline materials under TEM observations. Bayerite showed the presence of triangular particles and some short-range-ordered materials. [Pg.162]
