The Spectacular Rocks of Mataikona, New Zealand

- At Mataikona, near Castlepoint on the Wairarapa Coast, New Zealand, there are rock strata that have been tilted and eroded to form long straight lines along the sea shore. These were formed as turbidites (submarine mudflows) about 20 million years ago that were depositied repeatedly over thousands of years.

I can not look at rocks the same way anymore. I used to just walk across them and think nothing of them. This is a great channel. I’ve seen very similar rocks and structures between Ohope and Whakatane in some of the smaller beaches
Thanks for your interest!
Been there so many times, always wondered how these came to be. Cheers.
As a little kid having to help my dad carry the sacks of paua back these rocks were a real pain to traverse.
Great place to grow up I imagine
I live smack fan in the middle of the US but I am really enjoying these videos, so clear and informative.
Thanks for that feedback - great!
Oh wow that's awesome
Glad you think so too!
What a beautiful place!
That's for sure!
Love it...
That is amazing, I would love to visit, could spend days looking down there. Thanks for sharing. A jewel for Geologists. NZ is beautiful, and geologically, fanastically ineresting.
Thanks for your enthusiastic comment!
Jules this is a brilliant and inspiring description of the many land formations you are revealing through your videos. Thank you
Thanks Onny!
Better than a poke in the eye with a mud flow! How cool.
I think that is definitely true...
Wow, the geology in NZ is absolutely amazing.
Thanks you for all your knowledge and effort also, hats off to you Sir. :)
Glad you enjoyed it
Awesome video, thanks for sharing.
Cheers
Magnificent! I want to head over to NZ now.
You should!
Love it! What a wonderful scenery!
Great that you love it too!
Amazing geology!
Yep!
There is a similar rock platform in Kurnell Sydney that has massive parallel sandstone patterns, but that one is much higher in elevation. It's on top of a cliff beside the sea.
Educational, Magical, Historic, so interesting & real awesome watching...thank you very much.
What a kind comment - thank you
I love geology. Rocks Rock! This formation is just beautiful, and I hope to get back to visit NZ one day. If I do get back across the Ditch, I will visit this site.
Thank you so much.
@@stephanieyee9784 great!
Super informative. Thanks!
Thanks!
Amazing. And well explained. Thanks.
Cheers!
Wow, that’s stunning. And such a clear explanation. I really appreciate your videos.
Thank you!
Amazing looking.
Was surprised to find sea shells on the tops of hills locally when walking in that area. The uplift must have been very rapid.
great observations
Great Channel 👍🏼
Thanks
That's amazing and interesting and I have to be educated about my own country by a pom! :D
Lol, glad you find it interesting 🙂
Hi are there any florescent rocks that can be found in new Zealand with UV light thanks
Not sure sorry
There are some like this on the north coast of Mahia Peninsula.
Yes indeed - very similar
I have been to Castlepoint but missed this gem of rock formations so thank you for sharing. I wonder how sea rise will effect places like this.
I guess it will cover it over with water and sediment and at the same time extend the platform inland as it erodes further into the coast. But maybe another earthquake will equalize the levels again for a while. Who knows?
Used to camp there
Going by your visual description, the ridges get older towards the ocean?
Yep
But how did it get turned in its side!
That is the geological power of tectonic plate collision! Pushing and shoving in the earth's crust...
If the stone was formed from ocean sediments, does that mean it's Greywacke? Or is greywacke formed from a different process?
Please make your vlogs much longer
I guess that is better than being asked to make them shorter! :-)
That’s some good rock
In Hawaiian “makai” means “towards the ocean” and “kona” means “leeward”. Is that cognate?
Interesting. Could be, but I have no knowledge of the linguistics
Looks like petrified timber
Sort of I guess
A cataclysm caused them to rise up as one unit a thousand meters and not be broke to hell and back with bumps cracks ?
At first glance I'd have to say BS. Probably the second and third too. It is stunning I will guarantee.
It looks biological.
No erosion lines
Well there goes the quip about god not building in straight lines
Lovely, but you completely failed to tell us the amount of time per metre of strata. Why do geologists always do this? We have no idea whether this exposed section took 200 years to accumulate, or 2,000 years, or 20,000 years, or even 200,000 years.
It's the one question everyone who watches this video wants answering, and you don't address it!
Thanks for your comment, but I can assure you that I failed to tell you much more than just that! At a guess I would say that each of these turbidites will represent hundreds to more than a thousand years between events so your 200,000 years suggestion is more likely to be in the ball park. To know the time frame accurately for these sediments we would need to be able to date individual layers or even clusters of them, which is a level of detail that is not available as far as I am aware. But now that you have got me thinking, I wouldn't mind finding out more myself about deposition rates for these sediments. Cheers
*for personal reference the combination of mud rock and granite like China sinkholes*
1000s ? Millions!
Sure, quite a few thousands 🙂
@@OutThereLearning 20 million ago doesn’t sound long when you study the true history of this planet.Thanks for your information.
Ancient tree or log washed ashore and pretrified. That be bark
That would be one hell of a big tree! But I do like the comparison with growth rings which is neat
@@OutThereLearning And the moeraki boulders are petrified seeds from that giant tree.............
@@branni6538 there would be a ton more of them if they were
@@Lara-234 I'm not one of the huge tree believers. I was merely being sarcastic. If there were loads of seeds they wouldn't have to all be in one spot. Erosion being a factor too. Whether there were huge trees or not..........I don't know. God does though.
Do those faults represent past earthquakes ?
Yes, they do.
Still 33 it must be a cotravershial
Only 33 comments.....off
That's the remains of a giant tree
