...) dehydrogenated structures such as for curite and spriggite. The outlying value of the synthetic PbUOH phase (Li and Burns 2000b) is due to the density of the bond-valence acceptors within the framework as compared to the relatively simple complex occupying the channels. The high charge density of the REE III...
