This map shows the main deposits of clay found in New Zealand. The Matauri Bay deposit of a kaolin clay known as halloysite has a worldwide reputation for its purity and its whiteness.
Mineral Map of New Zealand Infographic. Aotearoa New Zealand has a wide variety of minerals found both onshore and offshore, including coal, gold, silver, ironsand, aggregate, limestone, clay, dolomite, pumice, salt, serpentinite, zeolite and bentonite.
Clay minerals may be classified into eight main groups on the basis of variations in structure and composition: (1) kaolinite, (2) smectite, (3) vermiculite, (4) illite, (5) pyrophyllite, (6) chlorite, (7) palygorskite, and (8) allophane (Table 1). Some clay minerals are intermediate between the clay mineral groups, formed by mixtures of the ...
Rock (crushed into aggregate), limestone and clay are the bulk products that dominate New Zealand's industrial mineral output. Millions of tonnes are dug, blasted and gouged from the earth each year.
