Abstract

The Raohe accretionary complex (RHC) is located at the eastern of northeast China and adjacent to Russian Far East. As a part of the Circum-Pacific Orogenic Belt, it is the unique region of the accretionary orogenic belt, which is associated with the subduction process of the Panthalassic-Pacific Plate (PPP). We synthesize the detrital zircon ages of terrigenous clastic rocks of the RHC and tectonic units along the East Asian Continental Margin (EACM) to clarify its provenance. Then we place the docking position of the RHC adjacent to the South China Block, and determine that the final accretion of the RHC occur during the later Late Jurassic (~150 Ma) according to combination for ages of stitching plutons and terrigenous clastic rock. Integrating with the published global-scale plate kinematic frame, we restored the pre-docking motion path of the RHC using the Gplates software. The reconstructed scenario shows that it is a long distance of at least 1000 km between the proto-RHC and continent margin when the basaltic volcanism occurred subaqueously within the abyssal basin of the PPP. This model also provides a probability that the proto-RHC and the proto-Yuejingshan accretionary complexes have the same drift history, before their simultaneous emplacement into the continental margin.

东北饶河增生杂岩的运动学重建:陆地地质证据与全球板块模型的整合
饶河增生杂岩位于中国东北东部,毗邻俄罗斯远东地区。作为环太平洋造山带的一部分,它是独特的增生造山带区域,与泛太平洋板块(PPP)的俯冲过程有关。通过对东亚大陆边缘陆源碎屑岩与大陆边缘构造单元碎屑锆石年龄的综合分析,明确了其物源。根据拼接岩体与陆源碎屑岩年龄的结合,确定了华北陆块与华南陆块的对接位置,确定了晚侏罗世晚期(~150 Ma)是华北陆块的最终增生期。结合已发布的全球尺度板运动框架,利用Gplates软件恢复了RHC的对接前运动轨迹。重建情景表明,当玄武岩火山活动发生在PPP深海盆地的水下时,原rhc与大陆边缘之间的距离至少为1000 km。该模型还提供了原rhc和原岳景山增生复合体在同时侵位到大陆边缘之前具有相同漂移历史的可能性。
