文摘
- •
Describe gas-related anomalies in echograms from Brazil, Argentina and South Africa.
- •
Discuss gas structure variability amongst diverse settings.
- •
Type of gas features depend on palaeo-environmental scenario and sediment grade.
- •
Gas is associated with the postglacial transgression and infilling of low topography.
