Increasing accessibility to Myanmar has allowed a resurgence of geological research in the country. Myanmar is geologically rich, with the famous Mogok Mineral Belt in the east and shows evidence for oil and gas in both the Central Basin and the offshore basins to the south and west. Despite numerous plays with proven reserves, very few field-based studies have been conducted on land and the sedimentary systems are still poorly understood.

The Central Myanmar Basin, bounded to the west by the Indo-Myanmar Ranges and to the east by the Sino-Myanmar Ranges, is a north-south elongate basin. It is subdivided into a series of sub-basins, including the centrally located Salin sub-basin.
