- •
LPO strength and grain size increase with quartz content, most rapidly above ∼70%.
- •
Where interphase boundaries are few, GBM strengthens quartz LPOs and weakens the rock.
- •
Where interphase boundaries are many, pinning occurs, quartz LPOs are weak, and GSS creep dominates.
- •
GBM may lead to dynamic growth of large, well-oriented quartz grains.
