Moeraki Boulders are spherical boulders that have been a famed tourist attraction on the coast between Dunedin and Oamaru. How did they form and why are many of them falling into pieces on the beach?

Thanks Julian and everyone involved in making this video happen. The more I learn about the geological process of the earth, the more fascinating and addictive this study becomes.

I think the softer muddy material gets washed off after they erode from the cliff, leaving only the hard cleaned concretions. Just guessing though!

I love this place, and always stop if I'm passing through. I've even climbed into the centres of some of them. My fave boulder is the one you show at 3:05. A few questions: 1) How far back does that mudstone layer extend? Is there any way of knowing? 2) does this occur elsewhere on Earth? As in: are there other places where similar concretions have emerged to surface? 3) Can you offer a speculative answer to the following: how many of these layers might exist right now, still buried? The formative processes would surely have occurred over millions of square kms in those prehistoric oceans.

Concretions are actually quite common, and there are many other places where you can find them in New Zealand in both the North and South Islands. These ones are appearing out of the Abbotsford Formation, which was deposited in the Paleocene (66-56 million years old). What makes these concretions so famous is their particularly spherical shape. Often they are less regular elsewhere

OK... thats why they formed....why only here? Any others on the planet? Are there more to be "unearthed"? Might the breaking ones be "renovated" or should we be satisfied with some sort of photographic record ( like what we have left of the Pink and White terraces?)

My question is that the boulder you mentioned breaking here, was caused by the hitting of another rolling down Boulder? and I also believe that these boulders were created by actions, watch the surrounding soils suggested that before the soils formed the boulders already existed, nothing shows that these boulders had been growing to present ones.considering of similar layer they emerged and such narrow and long belt of these deposited area, I believe they are made by some actions,

The boulders fall apart on their own. They are not that uncommon in similar rocks around NZ and have been studied a lot.

@@OutThereLearning yes, you're right. Because they are not common all around NZ, apart from those on the shag point near moeracki beach, even in the whole world. The pattern of the cracks on the surface of the boulders are very familiar to me and we could find rocks with similar surface pattern easily ,and what I'm going to say is the boulder apparently had not been grown in this way but made by some natural actions, you know what I mean? I had a hypothesis of action of making those moeraki boulders, and use this I can give a relatively clear picture of local geological event of past, answering why those boulders had been fund similar level of land and in a such narrow belt of land, many thanks, kirk

Been watching your videos over the last few months now, I'm going to tell you some hard truth about that area, and specifically those rocks which are actually 100% biology so please don't be offended Local iwi and surrounding iwi spoke about body's turnt to stone, if you know earth's real history then you will know large large creatures roamed this earth, an I'm talking some 1000ft+ tall. In Moeraki folklore the entire area was a large giant who now lay to rest, the boulders on the beach are what you would call Tendon Balls, which are anchors that hold and allow our Ligaments, Tendons etc to move back n fourth wile attached to the bone. You also notice there are Tendon Balls in the cliff, now let me tell you about the cliff which is layers of skin, take a close look at the distinctive lines and layers in cliffs which is not a natural phenomenon it is actually layers of skin and membrane and interstiching. The Tendon Balls are anchored in the skin which is the cliff. The local iwi hide these Truths from the public as well and for good reason. Let me tell you about why Māori people are so connected to there Maunga ( Mountains )?? Majority of the Maunga ( Mountain ) ranges are body's of large giants, usually the nose of the giant creature is the highest point, it's all biological my friend There's truth to there being a flood or mud flood in the ancient past, Māori hide alot from the common folk, so do all other indigenous cultures around the world and for good reason they are protectors of the land and the real history Some of the old Cheifs in certain parts of NZ were 7 - 12ft tall people. That's another story for another time when it comes to giants. Have a good day / night people
