Welcome to our page, Tektonesiana. We, Indonesian geologists who share similar interests, use this page to post articles, which represent our works on the geology of Indonesia. Our interests are in the field of regional geology, sedimentary geology, stratigraphy, structural geology, geochemistry, and petroleum geology. We analyze outcrop and subsurface data to understand geologic problems related to tectonics of Indonesian region. These articles have been presented in scientific meetings, whereas some of them have also been published in scientific journals. We have many questions about tectonics of Indonesia and we want to share them with you.
