Abstract

Pressure-induced hydration of the clay mineral nacrite, Al₂Si₂O₅(OH)₄ is, in contrast to its polymorph kaolinite, partially irreversible. At ambient conditions after pressure release, a majority phase with composition Al₂Si₂O₅(OH)₄2H₂O with an intense (002) diffraction peak near d ∼8.4 Å has been found. Both in situ X-ray diffraction and simulations based on the density functional theory point to intercalation of molecules in nominally nonswelling clays and specific geophysical and geochemical conditions.
