I have run out of superlatives to describe the information delivered in these superb video's given freely to those interested in Beautiful intriguing New Zealand, Kia Ora 'Out There Learning'. Stay well stay safe.
Coming from Tbay i can only think of the wonderful learning opportunities missed at school if we had only been taught more about our wonderful environment
Great stuff Julian. We chatted about video on the beach the day you were filming and the stuff you shared has changed our view of this beach every day when we walk it. As you said some days they are buried, others they stick out easy to see. Amazing to know we are looking at 100k old salt preserved wood! Keep on producing!
Went out there today at low tide and saw the trees! I couldn't go all the way around the point though (had my husband with me who isn't able to walk that far), but I will do in the future. Merry Xmas guys!
Thanks for sharing your knowledge, I wonder in fact how many people where unaware of this History ?? It points out with the facts of how long it’s been there, we as Humans are hear for such a nano second. My brother and Wife , with family live there, so I hope They enjoy it as much as myself ❤️☮️ fifi
Really interesting. I never knew that two of the layers formed at the same time, that they are a pair created by the difference in courseness of the sediment. I always assumed that each layer represented one time period.
Same here..... really learnt something, told the wife and she says " Did you only just realise that?" ..... she did a geology degree 50 years ago and never bothered to tell me how the rock bands formed when we used to walk Titahi Bay beach.
Great videos - Titahi Bay is an awesome location (I'm from Porirua so this is basically in my backyard) I've never really viewed it from a Geological sense so this was very educational. Pukerua Bay further north around the coast from there shows many similar features. Once you meet Paekakariki the rocky coast stops entirely.
All this and more along the Wainui to Eastbourne coast...... access a little harder, but drone pics of the raised beaches would be great, and the cut off lakes.... More please.
'All this and more along the Wainui to Eastbourne coast' I was exploring the cliffs along the Eastbourne coast a few days ago. Eastbourne in England, that is...
@@VincentComet-l8e You will find the NZ Eastbourne rather different. But still worth visiting..... the harbour ferry, Matiu, a great bushwalk, cycle to the lighthouse and Kohangapiripiri with amazing folded honeycomb rock exposure. And if you are up for it, continue the ride over the Wainui and along to the seal haulout and the raised beaches. Then you have to take the bike back but surely you'll be fit enough? Your cliffs have seen more human activity which makes for even more interest than the natural history..... on the whole a better deal I reckon.;-)
Ace the Sydney sausage Great video! We live Right above the bay with the caves And look down onto them and have always been fascinated by the unique geology .You got a nice shot of our house on the cliff edge At the end :)
@@acethesydneysausage3521 and the reason that some of the caves are now beyond the reach of the sea is because the land has been pushed up by earthquakes since they were formed. Just in case that's interesting 😆
very cool geology, & description/explanation of the processes. my only quibble; i'da thought those tubidites wooda resulted from seasonal hurricanes etc, & much oftener then once a century. wish i could afford to go there & see those rocks firsthand.
Great quibble! Although sedimentation rates in the ocean vary a lot, an average of a few cm per thousand years is not uncommon, right up close to a continent it can be a lot more, and it is much less when you go far away from a continental margin. Also bear in mind that these turbidites would have sometimes spread over a vast area of hundrends or even thousands of square km of the deep ocean, so a huge amount of material was transported in each event. The size of Zealandia, which is the area of ocean floor that was being covered by these sediments (in many different events along the edge of Gondwana) is about 17 times the area of New Zealand, so we are talking about a massive process over millions of years. Titahi Bay shows the results of just a tiny portion of this huge and slow process. :-)
@@OutThereLearning ok, my major experience with turbidites is in the delaware mnt. grp. of the permian basin of west texas & new mexico. sedimentation rates were Much higher there.
Fantastic video! Beautifully, clearly explained history of the land, thank you so much for sharing, especially for those of us also on the pacific rim but far away (Oakland, California). Many of the phenomena you describe are familiar to the California coast as well, nice to see our Pacific ocean cousins on the other side enjoying it too. I am curious how many other natural features we have in common. Are they any forests in New Zealand whose only water source is ocean fog? Our redwoods don't get much rain - they depend entirely on the fog.
Thanks for your comment Jesse. In New Zealand we have a lot of rain and so there is no area that only has fog for moisture. But like California we have active faults from being at the edge of the Pacific Plate.
I had always assumed those trees had washed up on the beach at some point and been buried, I had no idea it was a fossilised forest. Where exactly is it the sea cave you walked through? I'd like to take a look myself next time I'm there.
Park at the start of Terrace Road, to the North of Titahi Bay beach, walk down to the rocky bay right there and go to the right. You will see the cave there
Love Titahi Bay, spent all of my childhood summer holidays there. When we think about the curved formation at 5.31, surely this bend has to represent a chaotic sequence of layering where the deposit was rippled when the entire composite was in a slurry state? From memory, there’s no gap in between the layers. If there were copious gaps throughout the strata it would suggest to my basic understanding of geology that the uplifts had sporadically occurred over a prolonged period of time. But as there are no gaps….how to multiple layers of solid state rock bend?
Fair question! Don't forget that they are several kms below the surface where the pressures and temperatures are relatively high. The sandstone is harder to bend than the mudstone which tends to accomodate more. But they are not very bendable which is why there are also lots of faults (breaks)
Great video. And, I never knew that it is called *honeycomb weathering* @4:30 and I believed it was man made (when I saw one on Sydney beaches)...like some artist made it from metal that eroded. As the shapes were too geometrical to be natural. Thanks.
Thank you very much for sharing this spectacular video!! A calming watch, very informative, beautiful videography. These dynamics make me think there would be lots of serpentinite around New Zealand's southern coast, is that so? Here in California there's tons of serpentinite, and a lot of it contains veins of jade. very pretty, but tough on agriculture.
Sometimes unconformities or disconformities are really difficult to spot unless they clearly cut across older layers. These beds are actually highly deformed also by faulting and folding
Wondering if anyone can explain why the ancient tree forest are the only fossils in Titahi Bay . There seems to be nothing in those layered bands of sandstone and silt stone?
The trees are much much younger and were preserved in a completely different, more recent past environment. They sit on top of the older marine sediments rather than within them, if that makes sense. Cheers
@@OutThereLearning Thanks for the reply, I did some internet searches for images of trees, lumber, descriptions of lumber usage, timbering activities and conservation work to produce the trees on a sustainable basis. I now know about podocarps, a family of plants we don’t have in the USA.
Geologists only talk and think in millions of years. They have different methods for determining the age of rock layers. However, there is one small problem. Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, higher than the highest mountain, flooding, storms, rain, volcanic eruptions, earthquakes, and a fiery asteroid bombardment. That planet is surrounded by a gigantic twisting cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So every layer on our planet contains material with the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
Really enjoyed that, spent the first 18 years of my life there so quite familiar with the formations, actually studied geology 101 at victoria now at 66 it all falls into place ... life long learning? Cheers.

Really interesting. I never knew that two of the layers formed at the same time, that they are a pair created by the difference in courseness of the sediment. I always assumed that each layer represented one time period.
Yep - the second layer (the finer material) takes a lot longer to settle, but it is from the same event

Thanks for this.. there is a blue sign that mentions this stuff in the nearby car park, 👍
There is indeed
Incredible stuff. Inspired, will go and check them ASAP with kids.
That's great! 🙂
Best bay. Thankyou.
Welcome 😊
how interesting.
Thanks for watching!
You can also see this on the SouthCoast from Baring Head to Sinclair with some extra features. [Pillow Lava, uplift and wave cut cliff edge]
Yes you are right!

Yes we do have serpentinite in places, particularly in the South Island, and also Jade (locally called Pounamu) which is highly prized for carvings.
So good ideas ideals place for electricity production
Very interesting. But I had to google it to find out it's located in New Zealand.
Good old Google!
Thanks for the interesting geology tour. But why millions of years which should, but does not show erosion between layers?

@@OutThereLearning Thanks so much for your reply. Really appreciated.
Just want to point out Titahi Bay is not on the Kapiti Coast ;)
Ah, rats!
@@OutThereLearning a small price to pay for such entertaining you tube content 👍👍
Have the species of the tree stumps been identified?
Mainly a mix of rimu, totara kahikatea. Probably growing in a swampy area with other plants such as tree ferns, grasses, nikau palms etc
@@OutThereLearning Thanks for the reply, I did some internet searches for images of trees, lumber, descriptions of lumber usage, timbering activities and conservation work to produce the trees on a sustainable basis. I now know about podocarps, a family of plants we don’t have in the USA.
that proses on the rock is from electric in the earth have you seen the pictures made with electric
Thanks for watching!
Interesting video, but you need to make a note that Titahi Bay is in Porirua, not the Kapiti Coast
Thanks! My bad..
Is it really a cave and not a tunnel?
I'll take either / or :-)
It's both ! Silly boy !
Wherever wellington is ok i will look it up mr narrative 🤓
New Zealand's capital city. Hope that helps 😀
Giant trees?
