| Species: | Hafnon | |
| Formula: | Hf(SiO4) | |
| Comments: | Two samples of zonated zircon-hafnon crystal from Conco (Morro Conco) were analyzed by XRF analysis among 7 other samples from localities in the Alto Ligonha pegmatites, Mozambique. The data for the sample (bulk analysis) gave a Hf/(Hf+Zr) ratio of 38 and 47, thus a hafnian Zircon. The samples were not microprobed. The zircon/hafnon crystal was zoned. The xrf data gave only an average, and didn't give a minimum-maximum range within a crystal. So it's possible that hafnon could exist as a zonated area in the samples or in other zircon-hafnon crystals at Morro Conco, but this was not proved by Correia Neves et al. 1974.
