江山-绍兴断裂带在杭州湾延伸的探讨

江山-绍兴断裂带斜贯浙江境内,是我国东部一条重要的大地构造分区界线。在浙江陆区部分,江山-绍兴断裂带基本上顺浙赣铁路方向,从江山沿金衢盆地南缘,经乌灶至绍兴平水、富盛。过绍兴后,江山-绍兴断裂带是否继续向杭州湾海域延伸以及如何延伸,则认识分歧。

According to the field investigation by the authors in the main islands of Hangzhou Bay and the mountain lands around it, and with reference to some new data of the seismic exploration and the oil-drilling, we obtained some new knowledge, i.e. Jiangshan-Shaoxing fault zone’s strike turns from NE to NEE direction over past Pingshui and Fusheng of Shaoxing City, it continues along Changhe and Yandong in north Cixi county, and finally stretches to East China Sea through Dajushan island of Daishan county.
