晚中生代伊扎那吉板块在东欧亚板块下的西北俯冲引起了燕山褶皱冲断带（YFTB）的一系列挤压变形事件，但山间盆地的构造变形时间、构造性质以及构造隆升与沉积的关系仍存在争议。为此，对北京北部地区千家店盆地晚侏罗世-早白垩世沉积学、物源及盆地结构进行了详细研究。结果表明，秦岭坳陷西缘发育断裂传播褶皱型生长构造和生长地层，土城子组二段和三段顶部为受翼缘旋转机制控制的生长地层。在QJB的两条小逆冲断裂中，中元古代下马岭组逆冲于土城子组之上，这些断裂可能控制了断弯褶皱型生长地层的发育。“源-汇”过程分析表明，上一—平泉断裂（SPF）上盘序列是秦岭坳陷晚侏罗世—早白垩世早期地层的主要源区。FPFT生长地层底部火山岩锆石206pb /238U年龄为140.8±2.4 Ma，代表了FPFT生长构造发育的起始时间。FPFT生长构造和生长地层的发现表明，早白垩世早期，QJB是一个受褶皱和冲断构造控制的山间弯曲盆地。在东西向的前家店逆冲断裂（QJTF）附近，北东西向的前家店逆冲断裂（QJTF）和两个小的基底内逆冲断裂可能构成了一个统一的右旋走滑系统，该系统是在侏罗纪-早白垩世东亚大陆下伊扎那吉板块向西北平俯冲过程中形成的。
The northwestward subduction of the Izanagi Plate beneath the eastern Eurasian Plate during the Late Mesozoic caused a series of compressional deformation events in the Yanshan fold and thrust belt (YFTB), but the tectonic deformation timing, tectonic properties and relationship between tectonic uplift and sediment accumulation in the intermontane basins continue to be debated. For this reason, the sedimentology, sediment provenance, and basin structure of the Qianjiadian Basin (QJB) in the northern Beijing region during the Late Jurassic and Early Cretaceous were studied in detail. The results suggest that a fault-propagation fold-type (FPFT) growth structure and growth strata developed on the western edge of the QJB and that the top part of Member 2 and Member 3 of the Tuchengzi Formation are growth strata controlled by the limb rotation mechanism. In two small thrust faults in the QJB, the Mesoproterozoic Xiamaling Formation is thrust over the Tuchengzi Formation, and these faults may have controlled the development of the fault-bend fold-type growth strata. An analysis of the “source-to-sink” process suggests that the hanging wall succession of the Shangyi-Pingquan fault (SPF) was the main source area of the Late Jurassic to early Early Cretaceous strata in the QJB. A zircon206Pb/238U age of 140.8±2.4 Ma for the volcanic rocks at the bottom of the FPFT growth strata represents the timing of the initiation of FPFT growth structure development. The discovery of the FPFT growth structure and growth strata in the QJB indicate that the QJB was an intermontane flexural basin controlled by fold and thrust structures during the early Early Cretaceous. Near the E-W-trending SPF, the NE-SW-trending Qianjiadian thrust fault (QJTF) and two small intrabasinal thrust faults may constitute a unified right-lateral strike-slip system that formed in response to the northwestward flat subduction of the Izanagi Plate beneath the East Asian continent during the Jurassic-Early Cretaceous.
