@hippopotamus6765 your talking about 1%. The majority are watching tiktoks and reels😅. Its very rare for adults/parents to be interested in Geology, im always told docos are boring. Education to a lot of people is boring, meaning they struggle to engage their minds. I come from a little small town that had the minimum of topics at school, but i love watching this type of content because there's so many why's and what ifs and history. How doe's ones mind go day by day not thinking,just watching meaningless reality shows or people flaunting their materialistic things they have slaved for🤷♂️.
This channel has saved UA-cam (and my sanity ..). Absolutely superb classical geomorphology. The stuff I grew up with. Please keep it up. Many thanks 😊
I grew up at Baylys Beach, and we were told about the lignite layers, but not how they were formed. Lignite was wonderful fuel for fires in the winter. Thanks very much.
Yes, it's a real beauty. Good to see all those warm periods in the graph too...we are just living in a small bit of a huge natural cycle! Thanks Bruce.
That was a really great explanation of the geology occurring at Bayleys. I wondered what caused those layers, I assumed it was Tsunamis that created the lignite layers. I'll give my partner a full explanation next time we go out there, I'm sure she will love it😅
I've done fossil seed/seed capsule collection at Bayley's Beach .Part from Kauri ,Miro or Matai seeds can be found plus Elaocarpus dentaus ,which today can be found in the north/south Islands ,but not Stewart Island .
I Love Geology because of the concept of Deep Time, Realising how old our planet is and how life persisted through all these changes. I find it comforting that Millions of years in the future, Life will no doubt still thrive despite all our efforts, and all remnants of humanity will be a short smear in the geological record, A layer of plastic and pollutants, a brief increase in Radioactive Isotopes, And then back to background of sandstone, greywacke and igneous rocks. Rock on dude, Thanks for the Videos.
Its also worth noting though that due to our spread of invasive species and wiping out lots of native ones that the composition of local ecology will look _very_ different in the far future, especially in places like NZ which were isolated for tens of millions of years and developed a unique and fragile set of ecosystems. Kauri and podocarp forest persisted for nearly 100 million years in NZ but I really wonder if it could persist for much longer sans humans managing all the invasive species that have now been introduced.
Love your videos Bruce! I did my geology degree at auckland uni but never ended working in the field. These Out There Learning videos keep me fully engaged with that world; keep them coming mate!
This is really fantastic, I cant imagine the number of cool stuff I must have just walked past in my life with no idea what they were. Love your content.
As a kid I always wondered what the black rock was at Baylys Beach (I grew up in Dargaville) and if it was some kind of lignite (not how I would have phrased it, but essentially what I would have meant) as sometimes bits of it seemed to have vegetable matter in it. I was hoping you might explain this and you did! This is fascinating - it's so exciting to hear the geology of the area explained. Thank you
Amazin, Thanks. Could you please briefly explain how the wood and leaves etc are so well preserved in the lignite? I've spent time on this beach camping and surfing and also a lot of confused time looking at all the layers in the cliffs/dunes. The wood in amongst the lignite that crumbles awya seems like it was living only months ago. Such an amazing place to wander around putting the pieces of the geological puzzle together.
Really good stuff i've learnt from your channel Bruce , takes me back to those early days around Thames and Rotoiti. Keep up the good work, must get in touch with you.
I thank you sir, very interesting. I often played there, and saw the bands in the cliff for sure, but never went close enough to see there was organic material in it. Though I did see isolated lumps with branches in it on the beach. it just never occurred to me there was such a span of ages involved, I thought it had just been buried in recent times. There are similar bands close to the summit of Hirakimata on Aotea.
Thanks Bruce. Very interesting. Do you know how the hard layers of iron pan in the cliffs form? Also, how far out to sea does the barrier go? Presumably it was wider before the current erosion.
There are two kinds of hard layers in these sand dune barriers - iron pans (limonite iron oxide) and silcrete (silica cemented sand formed during podzolisation beneath forests such as kauri). The latter indicates where there was a forest growing on dunes between the interdune swamps that accumulated the peat/lignite. The forest and organic soil have decayed away since burial leaving just the hard silcrete. Often (not always) the rusty iron pan is associated with the silcrete because the silcrete prevents water percolation through it. The limonite is formed by oxidation of the black titanomagnetite sand grains in oxygen-rich ground water and deposition of this secondary mineral often in the sand at about the upper level of the groundwater table at the time.
Amazing channel. Would you have any information on how mt manaia formed out Whangarei heads? All I can confirm nearby beaches/bays you can find treasures agates, carnelian,kauri gum probably fallen from the nearby peaks
Might have to watch again, hardly a chore, but what is the reason or mechanism for tall sand dunes? Where Manawatu has little elevation but far inland.
The Manawatu dunelands are young. The northern west coast dune barriers are old and composite and have been supplied with vast quantities of sand for a long period of time. Each time excess sand builds up on the back of the beach and it dries out it can be blown inland and wind can blow it up onto the high hills that already exist, and do not exist in the Manawatu lowlands (yet).
Its made from alpaca wool and very soft. The design is common in places like Peru (where this was bought) but sometimes imports can be purchased at craft fairs etc in NZ.
I think you said that the sand on the Northland west coast is of volcanic origin. Is this true? I'd love to see a video about this sand, and the processes involved in its transportation up the coast... and possibly even around the top of Cape Reinga and down the east coast. Also I've heard that the Kaipara is the boundary between the black and brown sand on the west coast. I find this fascinating. What mechanism is at play here?
All are still wood like the day they died. But a fossil is defined as any remains or trace of a plant or animal that has been preserved in rock. So these ARE fossils. Many older fossils (but by no means all) have been turned to stone by passing mineral rich ground waters (=petrified) but not these.
These videos should be presented at schools. Science was fun to a point, there wasn't any geology at the schools i went through.id rather learn about earth or the continent i live on before any other planet. Im going to absorb your knowledge with every video made. Thankyou for not retiring telling people their to noisey😂 no offense👍🏾
Thank you. I lived in Dargaville from age 9 to 14, so I know this beach well. I have an unrelated geology question: What is the relationship between Large Igneous Provinces and Iceland? In particular: If I was present during the creation of an LIP, would it be lava everywhere all the time, or something more like Iceland, where a given spot will go perhaps 10000 years on average between lava inundations? Could Iceland be the birth of a new LIP? For any non-geologists reading this comment: en.wikipedia.org/wiki/Large_igneous_province
Is it possible the tilt in the lignite layer talked about after 9 minutes in the video, could have been caused by unimaginably large tsunami as a result of meteorite impacts. The entire inland west coastal area of New Zealand has clear chevrons along it from inundations of biblical proportions. We now know that events such as the Younger Dryas were caused by such massive impacts. It has been going on a long time, and fairly frequently on a geological time scale
This is a good idea, but unfortunately there is no evidence of erosion, block tilting (the lignite is horizontal in the thickest part at beach level), sediment disturbance around the lignite bed, which is clearly where it was deposited with respect to the underlying sandstone. There is no evidence that any tsunami associated with a Younger Dryas on-set bolide impact which was over NE America.
Its kind of sad to think that in some way humans have put a stop to this sequence by removing all the forest. I really wonder what the place would have looked like blanketed in dense Kauri forest, and if we'd still have some peat swamps (the topography up top makes me think yes).
Yes, but did not wish to make the story any more complicated for the video. Sea level was even higher during the interglacial 400,000 years ago (MIS11), but this and MIS5e are the only two times it was higher during the period of deposition here at Baylys Beach.
Not quite sure what your question is asking, but natural climate cycles are the background variability on to which human caused global warming is superimposed. Hope that helps, cheers.
Cool bro I'm from new Zealand and yeah I look at what nature doing I'm 40year old and the weather changing and no one knows it lol and yes it is going backwards
It's criminal how little subscribers this channel has. World class geology communicators
Thanks for your appreciation!

Climate change as a cycle is not as taxable as man made, cow farts and other bad policy...

Due to the anaerobic/acidic environment in the original swamp .

Now that the area is being farmed and forests won’t grow what will the barrier look like in the future? Will there be a barrier that’s very thin?

Just pass the lighthouse in Eastbourne Wellington are some interesting rock formations that would interesting to learn more about
Is that kauri trunk fossilised or is it still wood ?

Baileys Beach is fascinating, dangerous to swim at though.last there fora few days visiting the giant beached whales a few years back.
Don't forget the eemian sea level was much higher than today, over 6+ metres higher.
Yes, but did not wish to make the story any more complicated for the video. Sea level was even higher during the interglacial 400,000 years ago (MIS11), but this and MIS5e are the only two times it was higher during the period of deposition here at Baylys Beach.
I wonder exactly where we are now
Much respect
It’s not millions of years old
The earth is breathing 🤯!
Does this mean it's not global warming but it is in fact the warm and cold periods you describe @ 1:00min
Not quite sure what your question is asking, but natural climate cycles are the background variability on to which human caused global warming is superimposed. Hope that helps, cheers.
There will be another ice age soon enough .
