Formasi Dacite lan Basalt
Tatanan
tatanan
dacitic magma wis kawangun dening subduksi saka lemah ndhuwur enom laut ing piring Continental felsic nglukis. luwih, ing satunggalipun saperangan wis hydrothermally ngrubah minangka quartz lan sodium sing ditambahake.
basalt formulir nalika lahar tekan lumahing bumi near vulkanik. suhu lava iku antarane 1100 1250 ° c nalika nemu menyang permukaan.
