Third Year Otago Geology Student Project Locations Animation (1984-2022)
Просмотров 862 года назад
One of the strengths of the Otago Geology undergraduate degree is the emphasis on field geology. In addition to many group field trips our third year tauira (students) complete an independent project. This animation, centred on Otago New Zealand, shows the locations of the 761 third year student projects completed from 1984 to 2022. www.otago.ac.nz/geology/study/papers/index.html?papercode=geol...

Heavy Minerals in Westland - Fieldwork (Otago Geology)
Просмотров 1823 года назад
Heavy (dense) minerals are useful indicators of interesting geological processes and often contain rare elements. In 2021 a group from Otago Geology headed to the mountains near the Buller River on the west coast of South Island of New Zealand searching for these heavy minerals. This video shows some of what they got up to and some of the really beautiful places they visited. Video by James Sco...
Looking for meteorites near Dunganville, New Zealand (Otago Geology)
Просмотров 3193 года назад
In 1976 an iron meteorite was found near Dunganville inland of Greymouth on the West Coast of the South Island of New Zealand. In 2021 a team of Otago Geologists, led by James Scott went looking for more of it. This video, created by Otago Geology MSc student Thomas Stevenson, shows some of the field activities that were undertaken. www.otago.ac.nz/geology/index.html www.otago.ac.nz/geology/sta...
OtagoGeology - Brussels Sprouts as Meteorites

Otago Geology students of Metamorphism and Metamorphic Mineralisation (GEOL274-374) generated their own meteorite impact craters using a variety of impactors into flour. The craters formed raised rims and ejecta blankets characteristic of real craters - although there are very few Brussels Sprouts in space and no sound...

Otago Geology - Antipodes Globe Animation
Просмотров 2913 года назад
The Antipodes - what does this mean? Australia and New Zealand are sometimes referred to as the antipodes. The term antipodes in this sense means the opposite side of the Earth - the furthest away it is possible to be while still on the surface of the Earth. However as illustrated in these images, Australia isn't actually 'the antipodes' to any land. It is antipodal to the North Atlantic Ocean....

please give me those symbols
hey, i need the symbols. where do I can get the symbols style for free?
Sounds like David Kilgour and the Heavy Eights.
Congratulations, it helped me a lot, thank you.
It shows that you add date for your first type... but farther along in the video you say the types are bedding, lineation, etc which can be the unique values... Can you clarify this?
I think you skipped the part where you list the different point types for the different measurements such as bedding, joint, lineation, etc...
Good advice; a lot of manual intervention. It would be ideal to be able to bring oreintated symbols and dips straight from a FieldMove KMZ file into QGIS. I'm on the case!
Thank you for this video, you got straight to the point and told us every step needed to make it look good on our maps!
You guys couldn’t check a few samples I’ve found. I actually witnessed a fireball. And I searched all over and found some rocks that resemble meteorites but I can’t get anyone to check them. Ive got some with greenish yellow circle crystals all over then, some extremely magnetic but I’m no expert would love to have them checked after having them for over a year.
Hello, try contacting Prof James Scott at University of Otago.
Thank you for the video very instructive! Is there a way to add symbology to all the values at once I have around a thousand values and it would take much too long to do this one by one.
very helpful😊 thanks
What software do you use to create the SVG files with symbols, is it QGIS?
Hello. I used Inkscape as it's free and versatile and does the job. See the description for this video for a few links and other information.
Lifesaver, thank you
thanks for doing this! Great.
Promo`SM 😑
Very helpful, thank you!
Great video. clear explanation. thanks for the video
🙂 PЯӨMӨƧM
A great tutorial, clearly explained
My hometown, 4 till 19. Volcanic landscapes were all I knew! (And "Hi!" - I might even know some of you.) So strange seeing it from the sky like this - so many of my memories dotted everywhere. (Some truly terrible! - Won't go into that one!) I did find this a bit rushed, however. Too 'swoopy'. I'd like to see a chronological sequence as the landscape builds and as the eruption-centres shift around. Then the erosion stages, the sea-level invasions .. until now. But with a more slowly-shifting, sometimes fixed POV. Okay, that's a big ask of any 3D animator!
Thanks Ged; nice to get some feedback including suggestions for a future animation.
Thanks for this video! Really useful. Do you have any tips on displaying strike/dip data into a 3D scene in ArcGIS Pro? I tried following the same steps shown here. However, the symbols do not keep their orientation as I rotate the scene (i.e. they do not move with the ground).
Thanks for your comment. For correct 3D display and rotation view the Symbology Properties for the symbols and under 3D behavior untick Billboard. Also set the elevation of the layer to be on the ground. You may have to add a cartographic offset if the terrain is steep. I hope this helps.
@@OtagoGeology It worked! Thanks a lot 😊
Great to see some QGIS content, cheers
More to come!
Fascinating Otepoti
Fascinating. Born in Dunners
Faults are cool but we definitely need more about the Port volcano. Come on, it's a volcano, the sexiest of all units! We have great exposures! It's a geological mystery! Okay, so maybe the tomography is hinting at a subducted plate window or something but whatever man, it's still not getting enough love.
Hello and thanks for your comment. Yes, volcanoes are very interesting too :-) What we have at present is our Dunedin Volcano animation (ruclips.net/video/6n5wNAShgvI/видео.html) and the Benson Map animation (ruclips.net/video/7wBChaKRloA/видео.html) but we're considering adding additional material.
I've never been to Dunedin that gives me an excuse to go down to visit
Good plan - call in to the Geology Dept if you have time. Perhaps a a visit to our museum - www.otago.ac.nz/geology/about/museum/index.html
Soundtrack?
It would be tragic to see this place torn up for gold. I hope it never happens.
That has already happened & nature has taken it back over.
🌱🌏💚
Noooo I want to know what the answer is!!
It's probably a pillow basalt platform like the stuff we have on the shoreline in Port or something like that. Not very sexy unless you're a rock person 🤷♀️
I didn't see any gold. Maybe you didn't find any. You struck some good weather.
Hi John; spectacular gold was found but it didn't make it to the video alas.
@@OtagoGeology That's cool. what do you call spectacular? Was it alluvial or hard rock gold? Cheers :)
Hard rock gold was the focus of the research - I can email you some pictures if you contact me via stephen.read@otago.ac.nz
I'm heading there what kinda gold was it and was there much?
Awesome!
