foidolites 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.
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.
