Abstract

In natural apatites, perinaphthenyl radical with spectral parameters g = 2.0018±0.0002, A1 (1H) = 0.62±0.01 mT, A2 (1H) = 0.2±0.01 mT is identified by EPR. The radical forms during annealing of samples in the air in a range T = 300–500°C and is stable over time for several months after the formation. It is detected in the only genetic type of this polygenic mineral, namely, in supergene insular apatites from guano phosphate ores.
