摘要:
提要:利用最新古生物、磁性地层年代学资料对鸡西群、龙爪沟群进行了年代地层划分,确定了两群形成时间为早白垩世凡兰吟期—阿尔布中期。同时采用层序地层、盆地形成动力学、事件地层学、盆地湖(海)平面升降曲线与全球海平面升降曲线对比等方法,对两群进行了综合对比,证实两群为同一构造—沉降旋回背景下的等时异相关系。笔者认为龙爪沟群自下而上划分为4个组,即裴德组、七虎林河组、下云山组、朝阳组,其在横向上分别对应鸡西群滴道组、城子河组、穆棱组、东山组。这一研究结果将对进一步讨论黑龙江东部中生代海陆变迁机制、地层、构造格架建立及煤矿预测等具有重要的指示意义。

Abstract:
Abstract:Chronostratigraphic division of the Jixi and Longzhaogou Groups has been made using the latest paleontological and magnetostratigraphic data and the ages of these two groups have been determined to be the Early Cretaceous Valaginian-middle Albian. Many methods such as the sequence stratigraphic approach, basin dynamic approach, event stratigraphic approach and correlation of the lake- (sea-) level fluctuation curve of basins and global sea-level fluctuation curves were used to make an integrated correlation of the two groups. It is confirmed that the two groups have an isochronous and heteropic relationship in the background of the same tectonic-subsidence cycle. The Longzhaogou Group may be divided in ascending order into four formations: the Peide Formation, Qihulin River Formation, Xiayunshan Formation and Chaoyang Formation, which laterally correspond with the Didao Formation, Chengzi River Formation, Muling Formation and Dongshan Formation of the Jixi Group respectively. The results of this study have great guiding significance for the further discussion of the Mesozoic land and sea change mechanism, establishment of the stratigraphic and tectonic frameworks and coal deposit prediction in eastern Heilongjiang.
