1. The center portion consists of interbedded sandstones, siltstones and mudstones, with minor carbonaceous shales . 2. The area consists of patchy sedimentary rock composed of pebble bed, sand stone, and carbonaceous shales . 3. At the top are the interbedded coal seams, carbonaceous shales and mudstones of the Taber coal zone. 4. Next is the Menefee Formation, the middle formation whose content features interbedded carbonaceous shales , siltstones, and sandstones. 5. The site consists of black carbonaceous shale formed from anaerobic mud deposited in a marine estuary on the Agulhas Sea. 6. Carbonaceous shales , such as the Marcellus, are a possible target for carbon capture and storage for mitigation of global warming.7. The nonmarine rock is primarily sandstone, with some coal, shale, " black " or carbonaceous shale , and siltstone. 8. Lee described the formation as a coal with carbonaceous shale with brown to buff sandstone and conglomerate ( usually at the base ). 9. Abundant plant fossils like fern leaves can be found on the carbonaceous shale , characterising the Damuda coalfields and indicating a Permian age. 10. It is Late Campanian to Early Maastrichtian in age ( Edmontonian Land Mammal Age ) and is composed of mudstone, sandstone, and carbonaceous shales .
