Nā Laʻana o ka Pohaku Metamorphic 24 ʻano

24 ʻano / pahu, pahu nui 39.5x23x4.5cm

Wahi a kā lākou genesis, mahele nui ʻia nā pōhaku i ʻekolu mau ʻano: nā pōhaku igneous (pōhaku magmatic), nā pōhaku sedimentary a me nā pōhaku metamorphic. I ka pōpō holoʻokoʻa, helu nā pōhaku igneous ma kahi o 95%, nā pōhaku sedimentary ma lalo o 5%, a ʻo nā pōhaku metamorphic ka mea liʻiliʻi loa. Eia nō naʻe, i nā ʻāpana like ʻole, ʻokoʻa loa nā lakio hoʻokaʻawale o nā ʻano pōhaku ʻekolu. 75% o nā pōhaku ma ka papa he mau pōhaku sedimentary, a ʻo 25% wale nō o nā pōhaku igneous. ʻO ka hohonu o ka mamao mai ka papa honua, nā pōhaku igneous a me metamorphic hou aku. ʻO ka pahu hohonu a me kaʻaʻahu luna i haku ʻia i nā pōhaku igneous a me nā pōhaku metamorphic. ʻO nā pōhaku Igneous i helu ʻia no 64.7% o ka nui o ka crustal volume, ua helu ʻia nā pōhaku metamorphic no 27.4%, a me 7.9% nā pōhaku sedimentary. Ma waena o lākou, hōʻike ka basalt a me ka gabbro i ka 65.7% o nā pōhaku igneous āpau, a me ka granite a me nā pōhaku mālamalama ʻē aʻe e pili ana i 34%.
ʻAʻole kū ka ʻokoʻa ma waena o kēia mau ʻano pōhaku ʻekolu. Ke loli nei nā minerals constituent, e loli nō hoʻi kā lākou waiwai. Ke loli ka manawa a me ke kaiapuni, e loli lākou i mau pōhaku o kekahi ʻano ʻē aʻe
