“…Hydrocarbon (oil and gas) production and shows sourced from or reservoired in Proterozoic to Cambrian successions occur worldwide, and are an important economic resource (Bhat et al, 2012;Craig et al, 2009;Ghori et al, 2009). For example, the Lena-Tunguska Proterozoic-Early Cambrian (microfossils and K-Ar dates on glauconites show the oldest date is 590 -680 Ma) petroleum province, which includes the Lena Trough, the Kansk Basin, the Tunguska Basin, and the Sukhana Basin, located on the Siberian Craton, northern Russia, has a total estimated resource of 2 Bbbl (billion barrels) of oil and 83 Tcf (trillion cubic feet) of gas (Ghori et al, 2009;Meyerhoff, 1982). In addition, three potentially economically viable Proterozoic oil and gas systems have been found in Australia (McArthur, Urapungan and Centralian), which have a combined estimated resource of over 2 Bbbl of oil and 10 Tcf of gas (Bradshaw et al, 1994;Jackson et al, 1986;Munson, 2014).…”
