- •
We ask – does AMS of deformed quartzite give information of SPO or CPO of quartz?
- •
AMS and EBSD data are integrated to evaluate relation between AMS, SPO, and CPO.
- •
Magnetic foliation is parallel to the SPO of quartz grains.
- •
Quartz c-axis is parallel to magnetic lineation only if prism <c>slip dominated.
- •
AMS gives information of SPO and not CPO of quartz.
