tatanan
trachyandesite punika, hard rock nggoleki-grained kang jinis metasomatite, ateges ngrubah basalt. iku formulir karo utawa tanpa crystallization, salah siji ngisor permukaan minangka rocks intrusive utawa ing lumahing minangka rocks extrusive.
nalika Feldspar alkali sing dijupuk saka granit, iku diganti kanggo granitoid lan mengko, dadi trondhjemite karo quartz minangka mineral utama.
