1.1 tatanan

nephelinite 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 rock pumice nalika magma cools supaya cepet sing atom ing nyawiji sing ora bisa kanggo ngatur piyambak menyang struktur kristal.
