The early Paleozoic and Devonian sedimentary rocks in the western part of the Yangtze Block were suggested to be derived from an exotic source that was once connected to South China. This conclusion was mainly based on that detrital zircons from these rocks give U-Pb age populations of 2400-2600 Ma,...
