摘要
吴川-四会断裂带是广东省境内的一条主要构造带,走向北东,长约350km,宽约10至15km。许多证据表明这断裂带的早期阶段是一条韧性剪切带。本文讨论了这带的宏观和微观构造并在研究区内进行初步的应变分析。
Wuchuan-Sihui fracture zone is a major structural zone in Guangdong Province. It strikes north-east, and is about 366 km in length, and 10～50 km in width. Some evidence shows that in anearly stage the fracture zone was a ductile shear zone. The macrostructures and microstructuresdeveloped in the ductile shear zone are discussed, and a preliminary study of strain in this area isalso presented.
