PETROLEUM IN GLACIALLY‐RELATED SANDSTONES OF GONDWANA: A REVIEW
The supercontinent of Gondwana (Antarctica, Africa, Australia, South America, India, the Arabian Peninsula, Madagascar and Sri Lanka) covered more than six times the combined area of the United States and Brazil. In this paper, the petroleum occurrences and potential of glacially‐related rocks of Ca...

The supercontinent of Gondwana (Antarctica, Africa, Australia, South America, India, the Arabian Peninsula, Madagascar and Sri Lanka) covered more than six times the combined area of the United States and Brazil. In this paper, the petroleum occurrences and potential of glacially‐related rocks of Carboniferous‐Permian age in this vast area are reviewed in terms of basin types, reservoirs, seals, traps and source rocks. Significant amounts of heavy oil, sourced by Precambrian algal‐rich shales, are produced from glacially‐related sandstones in some 20 fields in Oman. Bolivia has 27 oil‐ and gasfields sourced from underlying Devonian shales, and oil production occurs in two fields in nearby Argentina. In Australia, there is production from two basins: the Cooper Basin has 24 productive fields (mostly gas), and the Canning Basin has six small fields. In Brazil, four non‐commercial shows have been found in the Paraná Basin and one in the Amazonas Basin. In Paraguay, southern Africa and India, there is no production from glacially‐related sandstones.
