Adakite vs Blueschist
Definition
definisi
adakite iku sawijining penengah kanggo felsic rock vulkanik sing nduweni ciri geochemical saka magma kang wis ngandika bakal kawangun dening leleh sebagean saka basalt ngrubah sing subducted ngisor busur vulkanik
blueschist punika rock metamorphic kang umume biru ing werna lan kabentuk ing kahanan tekanan lan suhu kurang

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.
Wangun blueschist amarga metamorphism saka basalt lan rocks liyane karo komposisi padha ing tekanan dhuwur lan kurang Suhu lan kira-kira cocog kanggo ambane saka 15 kanggo 30 kilometer lan 200 kanggo 500 ° c.
