文摘
- •
Ultrafine spherical quartz (USQ) was discovered in the principal slip zone (PSZ).
- •
Rock friction experiments on siltstone generate USQ in pseudotachylyte matrix.
- •
USQ in the PSZ was the result of large fast slip on siltstone at shallow depths.
- •
Presence of USQ could be an indicator to determine the latest slip zone.
