Hi all! Welcome to our blog, Tektonesiana.
The name of Tektonesiana is derived from the word tectonics and Indonesia. Tektonesiana represents our ‘passion’ on tectonics of Indonesia.
We, Indonesian geologists who share the same interest, use this blog to post articles that represent our works. These articles have been presented in scientific meetings. Some of them also have been published in journals. We have many questions about tectonics of Indonesia, and we want to share them with you. Enjoy our blog!

This article, which has been presented AAPG Annual Conference and Exhibition, New Orleans, Louisiana, April 2010 explains about tectonics of a Tertiary deepwater intra‐arc basin that experienced inversion by thrust faults. Oil seeps along this area may indicate distribution of source rock. The expelled and migrated hydrocarbon could reach in to potential traps and accumulated in reservoirs in these basins. The tectonics and paleogeographic reconstructions of this basin are expected to reveal the characteristics of petroleum systems.
This work has been presented at INDONESIAN PETROLEUM ASSOCIATION, Thirty-Sixth Annual Convention & Exhibition, May 2012. The authors of this article explained paleotectonic evaluation of the WMO area, and suggests another potential play other than Kujung Formation. Seismic interpretation with some attributes and also ant-track method are applied to strengthen the exploration concept. Another play that is quite interesting should be added to exploration in this area. Syn-rift play can be found in the western and eastern flank of JS-1 with Ngimbang Formation as the objective, whilst the post Kujung play can be emphasized on the flower structure pattern as an indication of wrench faulting. This wrench fault is responsible for tearing apart the Rancak and O.K. Formations during intra Miocene.
This article is about the first discovery of outcrop-scale, fine-grained sediment waves in the left-side muddy overbank deposits relative to the down-current direction of the adjacent channel deposits in the lower Halang Formation turbidite system in a late Miocene back-arc basin, West Java. The present outcrop-scale examples can fill the gap in dimension and formative processes between laboratory-scale bedforms and modern large-scale, fine-grained sediment waves for elucidating scale-independent processes, which are responsible for the development of fine-grained waveforms in a deep-water environment. This article has been published in Sedimentary Geology.
