Tectonic controls on the hydrocarbon habitats of the Barito, Kutei, and Tarakan Basins, Eastern Kalimantan, Indonesia: major dissimilarities in adjoining basins


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).

Doubly Vergent Accretionary Wedge Active Tectonics in The Sumatra Subduction Zone

Mukti_2012_neotec ipa

This is an abstract of a talk presented at American Geophysical Union, Fall Meeting 2011. Active deformation along the western margin of the present day Mentawai forearc basin appeared as anticlinal ridges. Beneath the anticlinal ridges, the deformation zone exhibits (1) main backthrust, as the upward continuation of the Mentawai Backthrust in forearc basin, (2) seaward verging imbricated thrusts developed in the accretionary wedge and (3) the landward verging thrust developed in the forearc basin. The landward verging Mentawai Backthrust zone and together with the Frontal Thrusts, formed the doubly vergent active tectonics in the Sumatra subduction system.
