    Bentabol, Maria; Cruz, Maria Dolores Ruiz; Huertas, Francisco Javier; Linares, Jose (The Clay Minerals SocietyThe Clay Minerals Society, 2006-11)
    Mg-rich kaolinite and Mg+Ni-rich kaolinite have been synthesized in hydrothermal experiments (200 and 400ºC) from poorly crystalline kaolinite and Mg- and Mg+Ni-bearing solutions. Al-rich serpentine and Al-rich chlorite ...
