This work presents finalized results of our paleomagnetic study of Paleozoic rocks of Henrietta, Jeannette and Bennett islands and their implications for tectonic reconstructions. We discuss possible relationships of the Cambrian section of the De Long sedimentary basin with the Verkhoyansk margin of Siberia, the terranes of the Kolyma-Omolon group, the Chukotka-Alaska microcontinent, as well as with the structures of the submerged Mendeleev Ridge. We propose a new tectonic model, in which the De Long structures feature as the frontalmost part of a large transform system that existed on the periphery of the Siberian paleocontinent.

德朗群岛及上楚科奇褶皱带相邻构造的古生代构造和地球动力学

这项工作展示了我们对 Henrietta、Jeannette 和 Bennett 岛古生代岩石的古地磁研究的最终结果及其对构造重建的影响。我们讨论了德隆沉积盆地寒武纪剖面与西伯利亚维尔霍扬斯克边缘、科雷马-奥莫隆群地体、楚科奇-阿拉斯加微大陆以及淹没的门捷列夫海脊结构之间可能存在的关系。我们提出了一种新的构造模型，其中德隆构造是存在于西伯利亚古大陆外围的大型变换系统的最前沿部分。
