Sedimentary rocks provide key information on source-to-sink systems and the regional expression of plate tectonics. The abruptly changing provenance signature of sedimentary rocks is commonly ascribed to changes in the source regions, such as continental collision events, the rise of mountain chains, reorganization of river systems and climatic change. However, moving the positions of the sinks (depocenters) geographically can also change the provenance record, but this is rarely considered. Typically, large-scale strike-slip faults can transport depocenters for long distances, thus altering the provenance information. In this study, we present a systematic investigation of the provenance changes in the Sikhote-Alin orogenic belt in the Russian Far East to evaluate this process. The Central Sikhote-Alin Fault is a margin-parallel strike-slip fault that developed along the NE Asian continental margin from the late Mesozoic. Our new detrital zircon U-Pb data, together with a compilation of geochronological data, indicate two different types of provenance signatures available: the sediments to the west of the fault were mainly derived from the adjacent Central Asian Orogenic Belt, but to the east of the fault, they were mainly supplied from the Korean Peninsula, which is several hundred kilometers away. It is proposed that these different sedimentary rocks were juxtaposed by syn- and post-subduction sinistral displacements along the fault, and were not related to local variations in the source regions. Thus, understanding the shifting positions of depocenters is important when decoding provenance change because lateral displacement is critical for reconstructing regional paleogeography along oblique convergent plate margins.

同俯冲走滑断层形成增生造山带及其来源特征：从晚侏罗世到早白垩世东北亚锡霍特-阿林的见解

沉积岩提供了关于源汇系统和板块构造区域表达的关键信息。沉积岩物源特征的突然变化通常归因于源区的变化，例如大陆碰撞事件、山脉的上升、河流系统的重组和气候变化。然而，在地理上移动汇（沉积中心）的位置也可以改变来源记录，但这很少被考虑。通常，大规模走滑断层可以长距离运输沉积中心，从而改变物源信息。在这项研究中，我们对俄罗斯远东锡霍特-阿林造山带的物源变化进行了系统调查，以评估这一过程。锡霍特-阿林中部断裂是中生代晚期沿东北亚大陆边缘发育的一条边缘平行走滑断裂带。我们新的碎屑锆石 U-Pb 数据以及地质年代学数据的汇编表明可用的两种不同类型的物源特征：断层以西的沉积物主要来自相邻的中亚造山带，但位于断层，它们主要来自几百公里外的朝鲜半岛。提出这些不同的沉积岩是由沿断层的同俯冲和俯冲后左旋位移并列的，与源区的局部变化无关。因此，
