| Abstract: | Electron probe analysis of a group of HF-soluble zircons from porphyroids of the Thuringian Forest, Germany, established yttrium, phosphorus, and iron to be the significant minor constituents. It is believed that these elements render the zircon structure HF-soluble. The Y content varies from about 6500–48000 ppm=0.83–6.10% Y2O3; the P concentrations range from a low of about 790 to a maximum of 4000 ppm=0.18–0.92% P2O5; the Fe content varies from about 400–15000 ppm=0.06–2.10% Fe2O3. Although both Y and P are distributed throughout each given grain, they are sometimes mutually enriched in growth zones. These zones are also resolved in reflected light micrographs and the electron images. |
