The origin of the Banda Sea region is critical to the tectonic development of eastern Indonesia. The purpose of this study is to synthesize the existing geological and geophysical data into a tectonic model of the Banda Sea Region, as an example of a marginal basin developed within and active arc-continent collision.
This thesis presents the results of a details trace element and isotope geochemistry study int the magma-genesis of volcanoes in the Adonara-Pantar Section (APS) of the East Sunda Arc in Indonesia, a setting where an oceanic island arc is colling with a passive continental margin.
Citra penginderaan jauh sangat penting dalam bidang vulkanologi, karena dapat memberikan data dengan cepat, mudan dan murah, sehingga sangat membantu sebagai pengumpul data geologi mauun vulkanologi. Dengan citra penginderaan jauh, dapat dengan mudah menentukan bentuk kawah, penyebaran litologi, penentuan daerah ahaya sementara dan daerah aman. Hasil interpretasi sangat tergantung dari pada ti…
