Tatanan
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.
itacolumite punika rock sedimentary kang formulir saka clasts wedhi-ukuran cemented lan jinis sandstone.
