Evolutionary characteristics of the sags to the east of Tan–Lu Fault Zone, Bohai Bay Basin (China): Implications for hydrocarbon exploration and regional tectonic evolution

Some Cenozoic half-grabens (sags) have been found to the east of the Tan–Lu Fault Zone in the Bohai Bay Basin, east China. The evolutionary history of these sags is consistent with the entire Bohai Bay Basin; besides, some remarkable characteristics which had not been mentioned in previous studies of the Bohai Bay Basin are presented, and they are the keys to understand the regional tectonic evolution. Among them, two characteristics are...
