| 中文摘要 | Nanograins are commonly observed in slip faults and ductile shear zones, and it is more and more widely accepted that nanograins can lubricate the fault, but the role of nanograins in the ductile shear zone is unclear. In order to study this problem, samples taken from the Xiaomei ductile shear zone, Hainan Island, were carefully observed with SEM and TEM. Our observations show that nanograins found in our samples can be divided into three types based on their morphologies: spherical nanograins (S-grain), rod-like nanograins (R-grain) and nanoclays. We find that nanograins are localized in the boundaries of the large minerals, and are likely to localize strain and decrease shear strength in the ductile shear zone. We think S-grains are mainly originated from milling process, and they can also come from solidification of melts and devitrification of amorphous materials. The mirror surfaces can decrease the friction coefficient, and the formation of layered materials is likely to represent the steady state creep. |
