The Coal-bearing Member is dominated by gray-gray black siltstone, silty mudstone and carbonaceous shale
and is intercalated with coal seams (M1-M5), while coal seam M5 is recoverable throughout the area.
Naresh Ghose, a Bengaluru-based geologist, first discovered the microfossils in a carbonaceous shale
in central India.
Ghose found these in the 2,000-million-year-old black carbonaceous shale
from the Bundelkhand region of the Gwalior basin in Central India.

The studyrevealed that Chichali Formation consists of glauconitic sandstone, ferruginous sandstone and carbonaceous shale
lithofacies and occasional limestone facies.
The Big Vein has a hard parting that typically measures from 4- to 6-inches thick with some carbonaceous shale
2f) and terminates with a claystone/mudstone intercalated with carbonaceous shale
(facies Fm) (Fig.
The Company secured 10 meters of coal and carbonaceous shale
and 6 meters of gassy sandstone that has all been put in sealed containers and forwarded for desorption testing.
He measured this interval as 2539' 1" (774 m) of grey and red mudstone, sandstone, limestone, coal, carbonaceous shale
and minor conglomerate.
Approximately 100 meters below the top of the formation on the Tibu anticline, remains of a few small mollusks were found in a highly carbonaceous shale
about 5 meters above a 2-meter interval of glauconitic very argillaceous siltstone.
Rust-brown to brown-orange stains, coatings and thin fracture fillings occur predominantly in the oxidized rocks above the phosphate-bearing carbonaceous shale
The world has extensive subeconomic resources of vanadium contained in oil sands, carbonaceous shale
, and bauxite.
