| Abstract: | The concentrations of platinum‐group elements (PGE) have been analyzed in primary magmatic magnetite samples from the Zhireken, Shakhtama and Aksug porphyry Cu‐Mo deposits (Siberia, Russia) by laser ablation‐inductively coupled plasma mass spectrometry to determine the range of PGE contents in magnetites and to check whether magnetite from two main rock suites (barren plutonic suite and mineralized porphyry suite) has distinct PGE composition. The results presented here indicate that magnetites are enriched in PGE relative to whole‐rocks. Comparison of ore‐related porphyry and barren plutonic suites shows that magnetite exhibit relatively similar PGE distribution patterns in both suites. Variations in Rh and Ru contents were controlled by the oxygen fugacity during magma crystallization. |
