tatanan
porphyry wis kawangun rong: magma cools alon jero ing lemah ndhuwur utawa magma punika ndingin kanthi cepet minangka erupts saka gunung mbledhos, nggawe butiran alit sing biasane bisa dideleng nganggo mripat wuda.
mylonites sing ductilely rocks deformed kawangun dening klempakan saka galur nyukur gedhe, ing zona fault ductile.
