Ko te kohatu taiao e tohu ana ki nga toka parataiao, toka waro kawa ranei penei i te mapere, te dolomite, te papake, kirikiri, toka me te toka. Ko nga kohatu taiao hou kei te kena mai i te toka taiao, a i muri i te raupapa o te tukatuka, I te korero mo nga mea e whakamahia ana i roto i te whakapaipai o te whare, te whare whanui whakapaipai kohatu taiao te nuinga o te granite me te mapere e rua nga momo.
Ko te Granite he toka ngiha, ka kiia hoki he toka plutonic crystalline acid. Koia te toka ngiha e tino tohatohahia ana, na te feldspar, te kiripaka me te titonga mica, toka maro kiato. Ko te nuinga o te Granite ko te hauhā hauhā, tata ki te 65%-75% o te toka e kiia nei ko te toka ngiha ko te magma i raro i te whenua, ko te hūnga puia ranei o te whakatioatanga rangitoto o te toka.
Marble is a metamorphic rock formed by high temperature and pressure in the crust of the Central Plain. The internal force of the Earth’s crust causes the qualitative changes of the original rocks, i. e. the structure, structure and mineral composition of the original rocks are changed. New Rocks formed by metamorphism are called metamorphic rocks.
