Pakistan's largest coal reserves are in the Sindh Province. The organic geochemical characteristics and petrographic characteristics of the Tertiary coals in the Thar coalfield, south-eastern Sindh Province, were investigated to their hydrocarbon generative potential and regional rank and to reconstruct the palaeoenvironment conditions during peat accumulation. The Thar coals are lignite to ...
