Kei te piki haere te aro ki te muka pātarati i roto i ngā ahumahi kakahu hangarau me ngā rauemi hiato nā te mea he pai te mahi ā-pūkaha, te pumau wera, te ātete matū me te roa.
He mea hanga mai i te toka pārūrū tūturu, ka taea te tukatuka i te muka pārūrū hei hanga i ngā momo hanganga kakahu hangarau, tae atu ki ngā papanga whatu, ngā papanga kore-kōpiri me ngā papanga whakapakari maha-tuaka. Mā ēnei hanganga ka taea te whakapai ake i te whakatakotoranga muka kia rite ki ngā whakaritenga ā-pūkaha o te hiato whakamutunga.
Nā tōna kaha kume pai, tōna pumau wera me tōna ātete ki te waikura me ngā matū, ka taea e ia te whakarato i te mahi roa i roto i ngā taiao uaua.
Ko tētahi atu painga nui ko tōna ngāwari ki te tukatuka kakahu. Ka taea te hanga i te muka basalt ki roto i ngā hanganga whakapakari me ngā whakatakotoranga muka rerekē, i runga i ngā whakaritenga o te tono whakamutunga.
Hei tauira, ka taea te hanga papanga biaxial me te whakatakotoranga 0°/90°, +45°/-45° rānei. Ka taea e ngā hanganga triaxial me te quadraxial te whakauru i ngā ahunga muka tāpiri hei whakarato i te whakakaha taurite ake, me te āwhina ki te arotau i te mahi ā-pūkaha o ngā rauemi hiato.
Nā ēnei āhuatanga, kei te whakaarohia te muka basalt mō ngā tono hangarau me ngā tono hiato, tae atu ki:
• Ngā mea hanga mō ngā waka me ngā waka kawe
• Ngā tono mō te moana me te hanga kaipuke
• Te whakapakari i te hanga whare me te hangarau ā-iwi
• Ngā taputapu me ngā hanganga ahumahi
• Ngā rauemi ātete ahi me te wera
• Ngā mahi ā-rangi me ētahi atu mahi hiato mahi-teitei
He mea nui te hangarau whatu miro maha-tuaka i roto i te hanga papanga whakapakari mahi-teitei. Mā te whakarite i ngā miro ki ngā ahunga rerekē me te whakauru i aua miro ki roto i tētahi hanganga papanga pumau, ka taea te hoahoa i ngā papanga maha-tuaka kia tutuki ai ngā whakaritenga whakapakari motuhake.
Mō ngā rauemi muka pārāti me ngā rauemi ranu pārāti, ka taea te whirihora i ngā mīhini whatu miro maha-tuaka ki te tukatuka i ngā miro whakakaha me te whakaputa i ngā hanganga rua-tuaka, toru-tuaka, whā-tuaka rānei. Mā te kaha ki te whakahaere i te whakatakotoranga muka me te hanganga papanga ka nui ake te ngāwari i te wā e whakawhanake ana i ngā rauemi whakakaha hiato.
