摘要白垩纪鹤岗盆地位于中国东北佳木斯地块，与松辽盆地被小兴安岭（LXR）隔开。地震解释表明，鹤岗盆地城子河组、穆棱组和东山组向东倾斜，向西上超，表明该时期LXR是一个古隆起，而后石沟组厚度变化不大，表明该时期LXR可能处于水下。鹤岗盆地城子河组碎屑锆石年龄约为180 Ma，只有LXR能提供，而后石沟组没有早侏罗世的锆石年龄记录。这一观点与前人对松辽盆地登娄库组与泉头组物源转换的研究是一致的。我们认为，在城子河组、穆棱组和东山组的沉积时期，LXR是一个高地，而在猴石沟组的沉积时期，LXR则处于水下。这标志着松辽-鹤岗盆地系的沉积中心和伸展中心向东迁移。这种向东的迁移意味着岩石圈的伸展是由古太平洋回滚驱动的。
Abstract The Cretaceous Hegang Basin is located on the Jiamusi Block, NE China, and separated from the Songliao Basin by the Lesser Xing'an Range (LXR). Seismic interpretation shows that the Chengzihe, Muling and Dongshan formations of the Hegang Basin thicken eastwards with westwards onlap, indicating that the LXR existed as a palaeo-uplift during that period, whereas the Houshigou Formation shows no thickness change, indicating that the LXR was possibly under water at this time. This is supported by results of detrital zircon analysis from the Hegang Basin in which the Chengzihe Formation is dominated by approximately 180 Ma zircons, which can only be provided by the LXR, whereas the Houshigou Formation records no Early Jurassic ages. This view is consistent with previous studies of the Songliao Basin for a provenance change between the Denglouku and Quantou formations. We conclude that the LXR was a highland during deposition of the Chengzihe, Muling and Dongshan formations but that it was under water when the Houshigou Formation was deposited. There was thus a connection between the Hegang and Songliao basins, which marks an eastwards migration of the depositional and extensional centre of the Songliao–Hegang basin system. This eastwards migration implies lithospheric extension driven by palaeo-Pacific roll-back.
