And the low percent of smectite in both mixed-layer phases reflects a high degree of burial metamorphism since the time of their origin.
Such clays would be expected to show a transition to more highly ordered forms during increased burial metamorphism (Altaner & Bethke 1989), particularly in shales and mudrocks undergoing basinal subsidence.

These conditions imply relatively high geothermal gradients (at least 50[degrees]C/km), consistent with burial metamorphism in a volcanic-arc setting.
These conditions indicate a metamorphic gradient between 25 [degrees]C/km and 50 [degrees]C/km, conditions best labelled burial metamorphism (Smulikowski et al.
