Te Anga is a rural community in the Waitomo District and Waikato Region of New Zealand's North Island. [1]
Waitomo District is a territorial authority, located in the Waikato region, at the north of the King Country area in the North Island of New Zealand. A small part of the district, the town of Tiroa, however, lies in the Manawatu-Wanganui region.
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by Cook Strait. The island's area is 113,729 square kilometres (43,911 sq mi), making it the world's 14th-largest island. It has a population of 3,749,200.
Marokopa River runs through the area. The river is not safe to swim in due to high rates of E. coli, [2] but farmers have put in plans to reduce water pollution. [3]
The Marokopa River is a river of the Waikato Region of New Zealand. It flows west for approximately 26 kilometres (16 mi) to join the Tasman Sea at Marokopa. The main part of the river is 40.5 km (25.2 mi) long, with about 533 km (331 mi) of tributaries. The catchment is some 364 km2 (141 sq mi).
The area transitioned from sheep farming to more intensive dairy farming at the turn of the century. [3]
The local landscape consists of limestones, calcareous mudstones and sandstones, with small areas of basal conglomerates and coal measures. [4]
Conglomerate is a coarse-grained clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts, e.g., granules, pebbles, cobbles, and boulders, larger than 2 mm (0.079 in) in diameter. Conglomerates form by the consolidation and lithification of gravel. Conglomerates typically contain finer grained sediment, e.g., either sand, silt, clay or combination of them, called matrix by geologists, filling their interstices and are often cemented by calcium carbonate, iron oxide, silica, or hardened clay.
The coal measures is a lithostratigraphical term for the coal-bearing part of the Upper Carboniferous System. The Coal Measures Group consists of the Upper Coal Measures Formation, the Middle Coal Measures Formation and the Lower Coal Measures Formation. The group records the deposition of fluvio-deltaic sediments which consists mainly of clastic rocks interstratified with the beds of coal. In most places, the coal measures are underlain by coarser clastic sequences known as Millstone Grit, of Namurian age. The top of the coal measures may be marked by an unconformity, the overlying rocks being Permian or later in age. In some parts of Britain, however, the Coal Measures grade up into mainly coal-barren red beds of late Westphalian and possibly Stephanian age. Within the Pennine Basin these barren measures are now referred to as the Warwickshire Group, from the district where they achieve their thickest development.
