Comments: | Hafnon was found in zonated ziron-hafnon crystals from Muiane. Bulk xrf data gave a Hf/(Hf+Zr) ratio of 53-78 in average. When the same samples were microprobed the results gave a Hf/(Hf+Zr) ratio in the range 92-97 on the "spot with the highest hafnon content". (Correia Neves et al. 1974).
