The Geology of Waitangi, Chatham Island

Ғылым және технология

Hamish Campbell explores the coastal rocks beside Hotel Chatham, Chatham Island, New Zealand.
These rocks are rich in many fossil species that inhabited the slopes of a small submarine volcano centred on nearby Tikitiki Hill. Overlying the volcanic sediments is another much younger layer that you can see on the beach - this time from the Oruanui eruption of Taupo Volcano, 25,500 years ago.

    You tell an awesomely interesting science story Hamish! I'm your old neighbour from across the road in Ngaio 14 years ago, and I still remember your cool explanation of the uplift layers out at Wellington Heads!

    The way the man says "perhaps the volcano's off..to the west!" is one of the most genuine wholesome sounding things I've ever heard. He just sounds so happy.

    the Chattam islands are not part of Aotearoa , which is the NZ mainland & the homeland of Māori . Rekohu - Chattam islands is the homeland of Moriori , who are a different Polynesian people than Māori .

    Wonderful to be able to reminisce about hearing all this first hand from Hamish while standing on Tikitiki Hill in 2022.

    We love your wee bits of info, sometimes attenuated factoids are the best way to learn something since it makes you put the other random stuff you know together with them. Haven't seen any obvious Taupo ash in Dunedin but I thought a teeny bit might have made it here. Suppose you'd have to ID the individual units to tease out which was local and what wasn't. Wish you could hire a geologist for a day and make them explain each weird local feature!

    It feels incredibly recent really, and what an absolutely catastrophic event it must have been! Here's hoping that Taupō holds off on the next eruption for a while yet.

    You are quite optimistic to assume that a few ten million years haven't changed the inclination of the layered rock. ;-)

    That is an excellent point. The Chatham Islands have been remarkably stable, only slowly emerging from the sea over millions of years with little tilting. Similar age rocks in mainland New Zealand (at the plate boundary) are highly deformed.

    Its actually Waiteke not Waitangi , there's a video on u tube titled Chattam island filmed for the first time from1947 and they still used Waiteke then .Although Maori changed the name in the 1800s people must have still used the Moriori Waiteke up till 1947 at some stage between then and now it became only the Māori Waitangi .

    It was a warm evening last night when you wrote this, but we've only had about 3 or so of them this spring or summer. Cool nights nearly always, and cool days quite frequently are what we have! Where in Canterbury do you experience permanent desert conditions? Sounds implausible to me, a central CHCH dweller.

    Excellent video. So this rock sediment came from where? Its not volcanic but has been eroded from where? Sounds like this volcano has "burst" through this layer?

    I want a box of the marine sediments with 50 million year old fossils. How much is it a kilogram? Can I buy 3 kilograms? Do you ship to America? That’s so interesting! I would have liked to hear how the underwater volcano rose so high.
