Accessory opaque oxides from hybrid granitoid rocks of the southern Snake Range, Nevada
Analytical data are presented for 12 magnetite and 6 ilmenite samples recovered from hybrid granitoid rocks of the southern Snake Range, Nevada. The magnetites are unusual for their very low contents of TiO 2 and for their similarity of composition over a range of petrologic types. The ilmenites are somewhat unusual for their high contents of MnO. Most of the titanium in these hybrid granitoid rocks is contained in biotite and sphene.
