| Summary: | <p align="justify">Timor Island was developed within interesting geological framework. The island was formerly a subduction zone which was later changed into Collision zone until presently. There has been some different development models of Timor Island which are still subjects to ongoing debate, namely overthrust model (Barber, 1981), imbrication model (Hamilton, 1979), and rebound model (Chamalaun and Grady, 1987). Research area consists of six units (from older to younger), which are: <br />
black, red, and green Claystone Unit with intercalated Sandstone, Claystone-Siltstone Unit, and Melange Complex comprises of Oolitic Limestone Block and Sandstone-red Limestone Block found inside claystone matrix. Provenance <br />
analysis using Dickinson diagram (1985) was performed in sandstone thin section of every unit to describe the provenance of every unit. Geological structures were developed in research area as responses to deformation (collision) that has been taking place until presently. Reverse fault and fold axis trend NW-SE, while transform fault trends W-E. Balanced crosssection and kinematic analysis are methods used to analyze those geological <br />
structures. According to two balanced cross-section reconstruction, there is difference in contraction value which is possibly due to tear fault. Based on balanced cross-section reconstruction, the formation of fold is related to reverse fault which tends to develop leading-type imbrication.<p align="justify"> |
