来自Kema和Silasa组（Albian，Sikhote-Alin造山带）的碎屑锆石定年的新结果允许确定沉积物的物源和地球动力学背景。Silasa组沉积在岛弧外环境中，被弧前盆地与内岛弧分开，其中Kema组沉积物堆积。弧前盆地的显著深度和宽度阻碍了大陆碎屑向Silasa组沉积区的输入。
New results of dating of detrital zircons from the Kema and Silasa Formations (Albian, Sikhote–Alin Orogenic Belt) permit determination of the provenance sources and geodynamic settings of sediment deposition. The Silasa Formation was deposited in outer island arc settings, separated by a forearc basin from the inner island arc, where the Kema Formation sediments were accumulated. The significant depth and width of the forearc basin hindered input of continent-derived debris to the area of sedimentation of the Silasa Formation.
