... layers, probably of H 2 O, can be seen in STM images of I/S particles that previously were cleaned for organic compounds and iron and aluminum oxides. On I/S particles, STM and AFM give data that hitherto have not been obtained by other methods and that provide insight into clay mineral diagenetic...

Abstract The shoreface translation model (STM) incorporates advances in the theory for coastal responses to changes in relative sea level, exposing some well-entrenched misconceptions about the formation of transgressive and regressive strata at chronosomal scales. The STM is a mass-conserving...
