I Was Wrong.

#asteroidcollision #asteroidimpact #westernaustralia
In the world of geology, the thrill of discovery often comes with a side of humility. Recently, I embarked on a journey to investigate a mysterious circular structure in Western Australia, initially convinced it might be an undocumented impact crater. The circular shape, concentric rings, and pronounced magnetic anomaly seemed to fit the classic signs of an ancient asteroid impact, making it an exciting potential find. With these clues in mind, I eagerly pieced together a theory of a cataclysmic event that shaped the landscape millions of years ago.

However, after receiving a comment from someone who had worked in the area, the evidence that came led me down a different path. What I thought was an impact crater turned out to be something equally fascinating but entirely different: the Mcintosh Layered Intrusion. Layered intrusions form from the slow cooling of magma within the Earth’s crust, leading to the formation of distinct layers rich in minerals like magnetite, which explained the strong magnetic anomaly. Unlike the violent birth of an impact crater, these intrusions are created through the gradual accumulation and crystallization of magma, which can create similar surface features, such as circular patterns and even central uplifts.

In this video, I walk you through my initial excitement, the evidence that pointed toward an impact, and the process of uncovering the true nature of the Mcintosh Layered Intrusion. We’ll explore what layered intrusions are, how they form, and why they can sometimes be mistaken for impact craters. This journey is a reminder that in science, being wrong is not a failure but a crucial step towards deeper understanding. Each hypothesis tested, even those that don’t pan out, brings us closer to the truth.

Join me as we delve into the fascinating geological story behind the Mcintosh Layered Intrusion, explore how it fooled me into thinking it was an impact site, and celebrate the joy of discovery—even when it means admitting you were wrong. After all, geology is about uncovering the stories written in the rocks, and sometimes those stories are more surprising than we ever imagined.

Kudos for your honesty and willingness to share updated information.

[barry]

I respect your channel even more, as failing to acknowledge an error is a common error in academics. You just passed with flying colours. Keep the vids coming, still have not spotted your Mega Fauna vids yet. Take care

[robdave]

You were wrong, you checked your findings, learnt more and took the responsibility to notify those you first informed of your error. You have my greatest respect. ❤

[JMc-xiii]

Ah well! Nobody is perfect! But highlighting your investigations on this great channel does make others come forward & tell everyone what these things really are. Without you doing this, we’d never know. Question away Oz 😀

[KateG-sc]

I'm so glad I impulsively subscribed to your channel the other a night. Your honesty is so refreshing - thankyou

[kellyezebra]

I love learning about different kinds of science, but my absolute favorite thing is when science educators like yourself show how science advances. It’s so rewarding to see a very knowledgeable person make a hypothesis and show how we can know if it is more or less likely to be so. Even better when you model asking for and accepting help from other knowledgeable people, learning more facts, and testing your assumptions. I’d have enjoyed learning about the macintosh intrusion in any case, but this addition to its story made it more rewarding! Whenever I see a science educator post a video with, ‘I was wrong’ anywhere in the title I get extra excite ‘cause we ‘bout to learn something! Thanks!

[peterpepper]

Thanks for the follow up Oz. It's how we advance our knowledge, and I have learnt so much about impact sites and and magma intrusions from both of these posts. A winner in my book.

[markmcd]

The 'laid' idea is likely correct, but it still looks like an impact with splash ejecta towards the south. So don't beat yourself up over it. And kudos for not simply moving right along as so many do when an error is pointed out!

[Hochspitz]

This is why having an invested community watching your videos adds to our collective learning. Thank you for the update and kudos to @mattdemmer for his comment.

[shanerooney]

You, sir, are both a Scholar and a Gentleman.

[Metalkatt]

I love the way you present this as "Okay folks, I was wrong, and the truth is actually so cool on its own, I gotta share it with you!"

It shows that it's okay to be wrong sometimes, and that you can learn a lot from listening to someone who nudges you about it. Too many people are so terrified to be wrong, they can't admit whe they are, and stick to disproven ideas in the face of all evidence to the contrary.

[konozal]

You just leveled up in respect in my eyes, admitting we get things wrong, specially to a large audience takes a lot of character and guts. Great stuff mate and keep up the good work

[justinm]

Not many youtubers would correct themselves. Loving both channels mate!!

[bartylobethal]

Great video. This channel has moved from "interesting" to "very good" for me: 1) admitting that previous speculation was unfounded and providing a detailed evidence-based alternative explanation tells me I'm dealing with good science content generated by someone with a genuine appreciation for the topic and the methods associated with it; 2) despite a long casual interest in geology and geomorphology, including some decades-old formal study, I hadn't previously encountered layered intrusions, so today I can say I learned something.

[imagseer]

Good. We need people like you to unearth (no pun intended) interesting geology and discover what processes were involved in its creation. Science only works because ideas can be tested and replaced where necessary.

[TheHoveHeretic]

Kudos to you! It takes integrity and courage to admit and correct your own errors and this clip has demostrated both. I knew there was a reason I subscribed here in the first place and I 'll be looking forward to future videos. 👍

[markthomas]

Please do a video comparing this to the Richat Structure. I love your correction to you guesstimation. From my experience, you can only really trust someone when you have been with them when they have got something wrong. It's how they deal with their errors that gives me the confidence to continue dealing with them. We are all human, so we ALL make mistakes. Those that don't acknowledge that cause a LOT of damage and waste a lot of time. You passed with flying colours, my friend.

[GarrisonFall]

It's good to see the scientific process at work. I'm fascinated by the 'size' of geological processes; like how molten rock, kilometres in volume, can 'move about' underground and the millions of years it takes to erode, lift, crack and whatever else to get us to what we see today.

[john-paulsmythe]

i have seen alot of videos about impact craters but this is the first time i have seen a video on intrusions, really good video.

[salmeza]

This one had me intrigued from your last video. Good to have an update!
