Summary:Analytical TEM shows that authigenic clay minerals have compositions which conform closely to ideal phyllosilicate structures; chemical variation is less than the classical literature might suggest. Analytical TEM, by virtue of its spatial resolution, can routinely avoid contamination by other phases and hence yield sound compositional data for clay minerals from various types of sedimentary rocks. Clay alteration mechanisms probably proceed via dissolution and replacement rather than by structural modification. [R.A.H.]
