文摘
- •
Plagioclase & (hemo-)ilmenite in all samples, additional pyroxene & magnetite in some
- •
Syncline with strong magnetic fabric (AMS, AARM, ± ApIRM) reflecting mineral fabric
- •
Minimum principal axes normal to foliation/pyroxene (100), maximum//pyroxene [001]
- •
AMS carrier: large multi-domain magnetite, hemo-ilmenite in pyroxene and pyroxene
- •
Magnetic fabric orientation independent of mineralogy, but higher k′ if magnetite
