5 Tatanan

5.1 tatanan

gneiss punika bahan dhuwur metamorphic rock IE wis ngalami luwih Suhu lan tekanan saka Schist. iku kawangun dening metamorfosis saka wangun gneiss saka rock vulkanik, krikel utawa granitie.

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