- •
Composition and pore characteristics of Ediacaran Lantian shales were investigated.
- •
Lantian shales are highly over-mature with high TOC content up to 12%.
- •
They are dominated by quartz, notable for abundant pyrite, highly varied carbonates.
- •
Bulk porosity and micro-mesopore volume show good, positive correlation with TOC.
- •
Relationships between minerals and porosity may also be related to the OM content.
