definisi
banget nggoleki rock fault grained kang dumadi saka matrik glassy sing asring ngandhut inclusions pecahan wall-rock.
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

tatanan
amarga kanggo ngganti ing kondisi lingkungan, rocks sing digawe panas lan pressurized jero nang permukaan bumi. pseudotachylite kawangun saka panas nemen disebabake magma utawa dening tabrakan kuat lan gesekan lempeng tektonik.
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.
