“…Globally, Precambrian organic-rich sediments are known to generate hydrocarbons. Source rock potential has been studied in the Potwar Plateau, Pakistan (Ahmad and Alam 2007), Australia (Rasmussen 2005), Russia (Vassoyevich et al 1971), and the USA (Palacas 1997) among other places. Precambrian coals are rarer still, because the land surface was yet to be colonized by plants capable of generating significant amounts of peat-forming biomass.…”
