- The South China Craton or South China Block is one of the Precambrian continental blocks in China. It is traditionally divided into the Yangtze Block in the NW and the Cathaysia Block in the SE. The Jiangshan–Shaoxing Fault represents the suture boundary between the two sub-blocks. Recent study suggests that the South China Block possibly has one more sub-block which is named the Tolo Terrane. The oldest rocks in the South China Block occur within the Kongling Complex, which yields zircon U–Pb ages of 3.3–2.9 Ga.

Charles Wilkes (April 3, 1798 – February 8, 1877) was an American naval officer, ship’s captain, and explorer. He led the first United States Exploring Expedition (1838–1842). During the American Civil War (1861-1865), he commanded USS San Jacinto during the Trent Affair incident in which he stopped a British Royal Mail ship and forcibly removed two Confederate diplomats, almost leading to war between the United States and United Kingdom.
