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