Abstract: Reconstructive transformations in layered silicates need a high temperature in order to be observed. However, very recently, some systems have been found where transformation can occur at temperatures 600 C below the ones predicted. We explore the possible relation with the existence of intrinsic localized modes, known as discrete breathers. It is shown that they can provide locally enough energy to produce the observed reaction rate.
