I mea e ʻoi aku ka lōʻihi o ke ola o ka ʻike daimana a ʻoi aku ka maikaʻi o ka hana, pono mākou e hoʻemi i ka ʻaʻahu o ka maka daimana e like me ka hiki. Ma hope aʻe, e kūkākūkā mākou me ʻoe pehea e hōʻemi ai i ka ʻaʻahu o ka ʻili daimana.

ʻO ka maikaʻi o ke poʻo ʻike daimana ponoʻī he mea koʻikoʻi e pili ana i ka ʻaʻahu ʻana i ka mea hana. ʻO nā mea e pili ana i ka mea hana ponoʻī, e like me ka pae daimana, ka ʻike, ka nui o nā ʻāpana, ka hoʻohālikelike ʻana i ka mea hoʻopaʻa a me ke daimana, a me ke ʻano o ka mea hana, ʻo ia nā mea nui e pili ana i ka ʻaʻahu ʻana i ka mea hana. E hoʻopili ʻia ka ʻaʻahu ʻana o ka maka o ka lau daimana e nā mea e like me ka mea i ʻoki ʻia, ka helu hānai i koho ʻia a me ka wikiwiki o ka ʻoki ʻana, a me ka geometry o ka mea hana.

Loaʻa nā ʻokoʻa nui o nā mea hana ʻokoʻa i ka paʻakikī haʻihaʻi a me ka paʻakikī, no laila pili pū nā waiwai o nā mea hana i ka lole o nā mea hana daimana. ʻO ke kiʻekiʻe o ka quartz maʻiʻo, ʻoi aku ka paʻakikī o ka ʻaʻahu daimana; inā he kiʻekiʻe ka ʻike o ka orthoclase, paʻakikī ka hana ʻana i ka ʻili; Ma lalo o nā kūlana ʻeli like, ʻoi aku ka paʻakikī o ka cleavage no ka granite coarse-grained i ka haki ʻana ma mua o ka granite fine-grained.
