文摘
- •
Lignites were analyzed using geochemical, micropetrographical and isotope analysis.
- •
A modified groundwater index is introduced based on ash content and micropetrography.
- •
Strong pore water exchange influenced peat/lignite composition.
- •
Temperatures based on GDGTs reveal a cooling trend initiated in the Upper Miocene.
- •
Isotopic trends support angiosperm-dominated flora and changing climate.
