This is a note about an article that explains about the different tectonic styles of Barito, Kutei, and Tarakan Basins during Tertiary and Pleistocene times. Diverse tectonic styles within the producing basins of Kalimantan compel separate exploration approaches to each basin. To discover new opportunities in exploration, the authors pointed out that it is important to understand the structural evolution of neighbouring basins. This article has been published in Journal of Asian Earth Sciences (1999).
