Sediments were sourced from the Jiangnan Orogen and northern Yangtze Block.
- •
Zircon Hf isotopes record a switch from subduction to collision at 860 Ma.
- •
A regional unconformity was developed along the Jiangnan Orogen at 830–800 Ma.

The Leigongwu diamictite in the Lantian section is a single Marinoan-age glacial unit.
