New Zealand
New Zealand is part of a continent call Zealandia, most of which lies under the ocean. It straddles the Pacific and Australian tectonic plates with its plate movements causing volcanic activity in the North Island and earthquakes throughout the country. Most of the South Island consists of rock known as greywacke that under heat and pressure was transformed into schist in the west and south. The North Island consists mostly of greywacke that has been covered by layers of volcanic rock. New Zealand has a well-documented ongoing history of geological activity, tsunamis, hydrothermal eruption, and landslides.
Hot Water Beach
Hot water beach gets its name from its underground hot water that with a little digging can become a natural hot tub or spa. Within two hours either side of low tide, it is possible to dig into the sand allowing hot water to escape to the surface forming hot water pools.
Hot Water Beach sand is a mixture of biogenic and geological sand grains with larger pink and tan off white grains of mollusk shells. There is one shell fragment on the left with parallel brown bands, a green sea urchin spine with parallel lines near the bottom center, and a generalized distribution of small sharped edged clear quartz grains along with tan, brown and black fragments of volcanic origin.

Wellington beaches have dark pebbly black sand that is typically high in iron content.
Large sand grains with variegated light and dark textures are metamorphic rock fragments with contours worn smooth by wave action. The glistening red grains are jasper. One small white sand grain near the center is a mollusk shell fragment that is partly covered by a large, mottled tan, gray and black metamorphic sand grain.
