Most zeolite became formed during diagenetic processes in sedimentary rocks (including volcaniclastic deposits) which can be grouped into several geological environments or hydrological systems (Hay and Sheppard, 2001), such as hydrologically open systems (Hay and Sheppard, 2001), hydrologically closed systems (Langella et al.
