Image INDONESIA geology map.jpg thumb 450px Geologic map This is a brief summary of the geology of Indonesia . Tectonics The tectonics of Indonesia are very complex, as it is a meeting point of several tectonic plate s. Indonesia is located between two continental plates the Eurasian Plate Sunda Shelf and Australian Plate Sahul Shelf and between two oceanic plates the Philippine Sea Plate and Pacific Plate . The Indian oceanic plate subduction subducts beneath the Eurasian continental plate formed the volcanic arc in western Indonesia. This chain of active volcanoes formed Sumatra , Java , Bali and Nusa Tenggara islands. The Pacific and Australian plate movements controlled the tectonic of eastern portion of Indonesia. Structural Geology The tectonics processes in Indonesia formed major structures in Indonesia. The most prominent fault in the west of Indonesia is the Semangko Fault , a dextral strike slip fault along Sumatra Island. The formation of this fault zone is related to the subduction zone in the west of Sumatra. Palu Koro fault is another major structural feature formed in the central part of Indonesia. This fault has similar orientation as the Semangko fault, extend from Koro in central part of Sulawesi , to Palu in the west coast of Sulawesi and extend across the Makassar strait to East Kalimantan . Stratigraphy The stratigraphy of the western part of Indonesia is relatively young, ranging in age from Paleogene to Quaternary . Eastern Indonesia has older stratigraphy compared to the western part. The stratigraphy ranges from Triassic to Tertiary .

It has been implicated in numerous large earthquakes . It is one of the 2 major faults created by the Australian and Pacific plate convergence, the other being the Ramu Markham Fault zone. Location The Sorong fault begins around Sulawesi and runs towards New Guinea . It marks the boundary between Halmahera plate and Bird s Head Plate.

Plate Evolution It is widely believed that fragments of the northern Australian continental margin in New Guinea are being detached and translated westward in this shear zone until they collide with the eastern margin of Eurasia Sundaland in the region of Sulawesi Island. However, the details of terrane translation , amalgamation, and docking remain poorly documented at this time. In particular, the timing of events is very poorly constrained, with estimates for the commencement of the SFZ ranging from early Miocene or older to Pleistocene .
