The soil here consists of ice and volcanic ashes
interstratified; and at a little depth beneath the surface it must remain perpetually congealed, for Lieut.
The Vertosol was a fine,
interstratified and smectitic dominant clay, Udic Pellustert (Soil Survey Staff 1999).
The presence of thicker sheets was expected as the vermiculite used as raw material consisted of flakes that correspond to randomly
interstratified vermiculite-biotite layers [30].
Chlorite
interstratified with a 7 A mineral: an example from offshore Norway and possible implications for the interpretation of the composition of diagenetic chlorites.
The Kona formation is mostly dolomite but also has
interstratified layers of shale, greywacke, chert, and quartzite.
In addition, the correlation between the calculated parameters including the full width at half maximum intensity (FWHM) for the 001 reflections and [xi] parameters [42, 50] can supply information about the hydration character of the studied samples (homogenous or
interstratified).

Second, the layers are
interstratified with thin, weak shale parting layers that allow easy separation (Bownocker 1915; Hyde 1953).
Reynolds (1988) characterized corrensite as a trioctahedral, 1:1 regularly
interstratified mineral (R=1), containing chlorite and smectite layers (low-charge corrensite) or chlorite and vermiculite layers (high-charge corrensite).
