... ). Tungsten deposits, however, are usually associated with reduced and F-rich granitic magmas, according to the low bulk-rock Fe 2 O 3 /FeO ratios and high F contents measured in ore-forming granites ( Ishihara 1981 , 2015 ; Harlaux et al. 2018 ; Azadbakht et al. 2020 ). Experimental studies have shown...

... anomalies. The hafnium-tungsten systematics offer a clear example: 182 Hf has a half-life of 8.9 My, so that after 50 My no more daughter isotope 182 W could be produced. Today the observed µ 182 W ( i.e. ppm deviation relative terrestrial standard) in MORBs and most OIBs is close to zero, but hotspots...
