\begin{abstract}
New shipborne surveys provide a closely spaced magnetic anomaly dataset
covering the East Subbasin (ESB) of the South China Sea (SCS). Magnetic
anomalies of seafloor spreading are identified using the dataset
supplemented with previous data and age constraints from recent
International Ocean Discovery Program Expeditions 349 and 367/368 holes.
We present a high-resolution oceanic crustal age model and associated
magnetic lineations of the ESB based on identified magnetic anomaly
picks. Seafloor spreading in the ESB initiated at \textasciitilde{}30 Ma
(C11n) and terminated at \textasciitilde{}16 Ma (C5Br). The spreading
direction has experienced a gradual counterclockwise rotation between
C6Cr and C5Er and a significant counterclockwise rotation at C5Dr. The
spreading rotations reorganized the orientation and segmentation of the
spreading ridge, resulting in the formation of a series of S-shaped
fracture zones. The interpretation of the magnetic lineations reveals
that three southward ridge jumps occurred at C9r, C8n, and C7n and a
synchronous jump occurred at C5Dr. Three southward ridge jumps
contributed to a total difference of \textasciitilde{}184 km in the
distance between the two flanks and left the paired magnetic lineations
C10r--C7r on the present-day north flank. The synchronous jump caused
the spreading ridge to rotate rapidly counterclockwise and obliquely
intersect the existing seafloor. We postulate that these ridge jumps and
rotations are common processes during seafloor spreading reorientation
and are dynamic responses to the plate or microplate tectonics around
the SCS.%
