The Grytalline Structure of Herderite, Datolite and Gadolinite
of isostructure-gadolinite. Its formula is obtained from the dato-
linite-formula. GaBSiO OH by replacement of the 5-charge-pair CaB
by YBe and introductign into the inversion-centers of the cell
(cf. figure 3 in reference 5) of 2 additional Fe** with a simul-
taneous replacement of 4 OH by 4 0. This leads to the formula FeY,-
-Be Si 0 in the case of 2 such"molecules" in the cell. An ana--
a m?lar to the above-mentioned ones was carried out for
