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.
websterite bisa kawangun minangka cumulates ing intrusions ultramafic dening klempakan saka kristal pyroxene ing dasar ing kamar lahar.
