The Metamorphic Gold Model - The New Zealand Story

Ғылым және технология

Dr Iain Pitcairn talks about his research into the origin of gold deposits in New Zealand's South Island. Iain analysed hundreds of samples from the Otago Schists to demonstrate that gold deposits were derived from fluids that formed during metamorphism of the parent rocks. This is the essence of the metamorphic gold model that is used to explain the origin of orogenic gold deposits. See more films about gold deposits at GEOLOGY FILMS Channel goo.gl/0mw8Z4

    The trace of the Alpine Fault at 5:23 is wrong. It does NOT pass through the lower North Island. Rather it splays at the top of the South Island into a series of faults. One such fault is the Hope Fault which links up to the Hikurangi Subduction Zone.

    i've enjoy studying gold and silver geology, i've often wondered why carbonates/ocean sedimentary limestone and marbles can sometimes make up huge world class gold deposits/mines from a generally low grade invisible/disseminated gold ore (carlin type), also mid to really high grades that contains visible grains of electrum on up to solid wires, sheets and nuggets of electrum, high grade gold, high gold silver, and at the same time, the exact same formation/s barren of mineralization, all within the same mining districts, this video gives me insight into the processes at work, great video, thanks for posting

    The simple answer is that all gold deposits do not form in the same fashion, and that ALL large gold deposits cannot be tied specifically to the orogenic and metamorphic model. Some ARE related to granites or their equivalents in relatively shallow-emplaced volcanic centers. The Comstock, for example, is a very different beast from California's Mother Lode (orogenic), from Carlin (a disseminated gold deposit), and is only a kissing-cousin to a big rhyolite-caldera hosted deposit like Round Mountain, Nevada, which has produced some spectacular coarse-grained gold. Yet all are only a day's drive from each other.

    The heat, pressure, and amount of fluids would have to overpower the density of gold and layers of opposing soils. In order for their theory to work

    I think you're all looking in the wrong place. Instead of looking for gold in rocks of parts per billion I think you'll find more gold in water. Especially at the ocean depths where metals are more concentrated than at the surface.

    There is gold in seawater but at extremely low concentrations of parts per trillion. There may be slightly higher concentrations in different parts of the ocean but ultimately any gold in seawater must have come from the rocks to begin with.
