- •
We report detrital zircons from the Pt3 and S-D strata in western Yangtze Block.
- •
The Pt3 sample (717–799 Ma) suggests local detritus supply and an arc setting.
- •
The S-D samples suggest typical Gondwana affinities of the source areas.
- •
Yangtze Block could have been adjacent to Himalaya region, north India in Paleozoic.
