tatanan
basalt formulir nalika lahar tekan lumahing bumi near vulkanik. suhu lava iku antarane 1100 1250 ° c nalika nemu menyang permukaan.
rocks adakite sing kawangun nalika cairan hydrous sing dirilis saka mineral sing break mudhun ing basalt metamorfosis, lan munggah menyang lapisan, banjur padha salat leleh sebagean.
