Abstract:

As an important part of the Rodinia supercontinent in the Neoproterozoic, the position of the Yangtze Plate has always been a hot research topic. In order to discuss the position of the Yangtze Plate in the Late Neoproterozoic (750-540 Ma), the relative positions of the Yangtze, Australian and Indian plates in the Late Neoproterozoic (750-540 Ma) are studied by combining the previously published paleomagnetic data and using the paleomagnetic research method. Based on the stratigraphic correlation, zircon dating and other evidences, the Yangtze Plate is placed in the present-day northern margin of the Indian Plate and the northwestern margin of the Australian Plate. Based on the analysis of the kinematic characteristics of Yangtze, India and Australia, it is considered that the Yangtze Plate moves to the high latitude area during the breakup of the Rodinia supercontinent. During the period of 750-635 Ma, the Yangtze Plate is in the middle-high latitude areas, and it starts to move rapidly toward the low latitude area at 635 Ma. Although Yangtze is placed on the northern rim of India, the two plates are not thought to be connected, until after their collision at around 570 Ma and both join Gondwana.

Key words: Yangtze Plate, Late Neoproterozoic (750-540 Ma), paleomagnetism, Rodinia
