Abstract/Notes | A brown gadolinite crystal from granite pegmatite at Lindvikskollen appears to consist of more and less calcium-rich members of a series RE2(Ca, Fe)Be2Si2O10· lts properties agree well with those of ordinary gadolinite, with the following notable exceptions: The spacings are on the average slightly larger, the birefringence is lower than 0.01, and the mean refractive index is 1.665 ± 0.005. |
