New Zealand has more than 15 billion tons of known coal reserves in the ground, and says that more than half of those resources are probably recoverable. In , New Zealand extracted . Uncertainty of gas saturation estimates in a subbituminous coal seam These two measures, together with reservoir pressure, give an estimate of the gas saturation of the reservoir. Typically gas saturation has been assessed by collecting one adsorption isotherm sample and assuming it is representative of the whole seam reservoir conditions. About.

Waikato Coal Measures are dominated by fine-grained lithologies, principally mudstone, with lesser proportions of sandstone and coal; conglomerate is rare. Most sediments were derived from the thick regolith, rich in pedogenic kaolinite, formed on basement rocks. Additional Physical Format: Online version: Edbrooke, S.W.

Abstract: The Waikatogeological map covers ab km 2 of the Waikato, King Country and north Taranaki, in the west of the North Island, New Zealand.
Otago coal deposits occur in two different geological settings. Coal deposits near the east Otago coast north and south of Dunedin are within coal measures of Late Cretaceous to Paleocene age. Kaitangata coalfield is the largest, covering a large unworked lignite deposit in the west and a multi-seam deposit in the east.
The Waikato Coal Region is New Zealand's largest coal producing area (Edbrooke et al., ). The slope stability research described in this paper was conducted in the Waikato Coal Measures, concentrating on three coal mines. The Waikato Coal Measures form the basal unit of the transgressive Te Kuiti by: Timing of normal faulting in the Waikato Coal Measures, New Zealand, and its implications for coal‐seam geometry Article (PDF Available) in New Zealand Journal of Geology.
The degree of thermal alteration that is produced by burning of the coal is variable and very much localized. This study focuses on a single outcrop that is situated 2 km southeast of Rotowaro, Waikato coal region, on the North Island of New Zealand (Fig.
The pyrometamorphosed coal measures include baked, partially melted, and entirely. New Zealand main geological resources are Coal, Gold, Oil and natural gas.
Coal has been mined in Northland, the Waikato, Taranaki, Nelson and Westland, Canterbury, Otago, and Southland. The West Coast contains some of New Zealand's best bituminous coal. The largest coal deposits occur in Southland.
Gold has been mined in the Coromandel and. Ferm classified lithological units have been identified and described in the Waikato Coal Measures in open pits in the Waikato coal region.
These lithological units have been classified geotechnically by mechanical tests and discontinuity by: The Waikato contributes between 20 and 25 per cent of New Zealand's mineral production.
Aggregate from Mesozoic rocks ranges from good (greywacke) to poor (argillite), with detailed differences being related to the position of the deposit within the New Zealand by: 6. The University of Waikato is uniquely placed to offer a thorough grounding in all aspects of the Earth Sciences.
We are situated close to both North Island coasts, a short drive from the active Taupo Volcanic Zone, at the heart of the richest New Zealand farming region, and have New Zealand. Coal measures. Coal measures is a name for coal-bearing sedimentary rocks, which include sandstone, mudstone and conglomerates as well as coal seams.
Coal measures mined in New Zealand are generally a few tens to several hundreds of metres. Coal mining produced almost 4 million tonnes of coal inof which 44% was exported. In it was down to 2, tonnes. New Zealand coal reserves are in excess of 15 billion tonnes, mainly in Waikato, Taranaki, West Coast, Otago and Southland.
Over 80% of the reserves are in Southland lignite deposits worth $ billion. Coal is produced from four underground and 21 opencast mines. PDF | Ferm classified lithological units have been identified and described in the Waikato Coal Measures in open pits in the Waikato coal region.

The Waikato region can be divided into four distinct topographical areas, characterised by our different landscapes: The map shows a simple picture of the main geology of the region.
Some are as old as million years. In places coal was formed, for example at Huntly. Find out more about the land and soil resources in the Waikato region.
Zealand Steel’s Glenbrook steel mill. Geology The Waikato Coal Region consists of coalfields developed 30 - 35 million years ago (the Eocene-Oligocene period).
The region extends from Drury (near Auckland) in the north to Mangapehi, south of Te Kuiti. The Waikato Coal Measures were deposited on an eroded ‘basement’ of Mesozoic greywackes.

Waikato coal region The Waikato Coal Region includes 13 coalfields and is New Zealand's major coal producing region (Edbrooke et al., ).
The Waikato Coal Measures, of Late Eocene age (Schofield, ), overlie Mesozoic basement rocks unconformably and are typically 30 to m by: 9. Inthe West Coast region produced 49 percent of New Zealand’s coal, while 41 percent was mined in the Waikato region.
The Southland, central Otago, and Canterbury regions of the South Island produced 9 percent, 1 percent, and a very small quantity, respectively. Eclipsed for years by its high-performing cousin natural gas, coal is making a comeback.
In Southland, Otago, Waikato and the West Coast—including at Spring Creek underground mine, north of Greymouth seen here—rivers of coal are flowing out of the ground to meet a burgeoning demand for New Zealand’s most abundant fossil fuel. When and why the Waikato changed course has been investigated by Vern Manville and Colin Wilson, two scientists working for the Institute of Geological and Nuclear Sciences.
They believe it was one of the consequences of the catastrophic Oruanui eruption of the Taupo volcano aro years ago. In a rail bridge was built across the Waikato River, which opened up coal mining in the western hills.
Mines grew at Pukemiro, Rotowaro, Glen Afton, Waikokowai, Renown and Glen Massey. Coal was shipped across the river by barge in the days before the bridge. In this ceremony marked the.

$ Add to Cart. An excavator loads overburden (soil and rock) onto a truck at the Rotowaro opencast mine west of Huntly. Overburden above the coal seam has to be removed before the coal itself can be mined. Opencast mining began in Waikato during the Second World War.
This group of miners worked together in the mids at the Huntly West mine in the Waikato region. They were known as the ‘Rotowaro shift’ because they all lived at the settlement of Rotowaro before it was abandoned to allow for opencast mining.

Huntly is the site of a massive coal-fired power station. It was once a major source of coal – the open cast coal mine produced aro tonnes a day when it was fully operational. Coal was first discovered here in by a local reverend.
In the s, one of the seams was opened up to provide coal for the river boats using the Waikato.

The geology of Glen Massey accounts for its rise and fall as a former coal mining centre.

New Zealand coals are mainly 25 to 70 million years old – relatively young compared to many overseas coal deposits. This is due to the highly active geology of New Zealand.
