Magma generation in arc systems is the most complex phenomenon and history compared to that in other tectonic settings. The magma source/or sources and process/or processes caused the wide geochemical variation of the rocks produced are widely discussed, but still no agreement among the petrologists and geochemists.

Negara Indonesia memiliki gunungapi yang terbanyak di dunia yaitu 129 gunung api aktif, atau sekitar 15 % dari seluruh gunungapi yang ada di bumi. Walaupun demikian, sangat sedikit sekali orang Indonesia yang ingin mendalami ilmu volkanologi. Lingkup studi mengenai gunung api meliputi petrologi, mitigasi dan evaluasi bencana, surve…
Central Indonesia consists of an assortment of micro continents amidst micro- oceanic plates. The map in Fig. 2.0-1 is based mainly on interpretation of various authors, checked for accuracy by bathymetric, Bouger gravity, and surface geology maps as well .. Deep sea basins are generally underlain by an oceanic crust. This is supported by …
