Rachel Hampton - Exploring the Origin of Economic Lithium Deposits 

I don't know a thing about geology and I thoroughly enjoy Prof Zentners lectures💯👍

Excellent!! Thank you again for allowing the viewers to be included.

Wow. another great presentation.

Nobody “juggles 4 things at once” like Nick! I hope you’re easy on yourself on this one. The talk on lithium was gold🤣. Thanks Nick.

In spite of the replay video-stream quality issues, the content was excellent. Thank you Nick and Rachel.

A really excellent and interesting lecture. This old woman not only understood a lot of it but also got a lot from it. My husband wandered in. I was able to pause the video and explain the basics to him. Obviously an important topic which is drawing people's attention. Thank you, Rachel and Nick.

This was a particularly successful lecture. Dr. Hampton hit a home run. Thank you for arranging for this Friday Forum.

Excellent. Even if there were some slides that were fuzzy, she explains well and is easy to just "listen" to the lecture. Very good and thanks to Nick and CWU.

This was a great lecture There was lots of discussion in the live chat Comments were respectful ..This lecture was extremely informative.Nice Job .Looking forward to the next Noon lecture .

Lost this completely during live. Glad it's on youtube

Great presentation! Wonderful discussion of what geologists do for actual jobs--something frequently (almost always?!) missing in college programs. Wonderful list of skills at around 56 minutes into the talk!!

Thank You Nick. Timely.

Thanks to CWU & Mr Zentner for hosting this talk.

Sharing this one! Wow! Thanks so much for this. All good!

Replay was better than live for me. Still glitchy in a few places, but much better on the whole. Excellent talk. Thank You, Nick and Rachel.

Excellent, thoroughly enjoyed!

Lithium is very expensive, and the price is not going down. It's also expensive to extract, and from brine it takes 500,000 liters of fresh water per ton and in the stone mining it takes about 100,000 gals. The waste water becomes polluted and is unfit to drink even when filtered. Lithium I think is a dead end for electric car batteries, as the pollution and C02 produced is as great as using oil products to power cars. Tesla batteries use 304 pounds of Lithium plus Cobalt and Nickle. Lithium batteries also have to keep cool, just parking a Tesla on hot pavement can start a fire. The cooling pump also runs off the main battery which shortens range.

Did a spot check of replay... looks good. 1130 watched first number seconds after posting done.

My mining buddy in Utah asked me if I knew anything about power generation. Always easy to forget how much coal, diesel and gas is going to have to go into this. Astronomical amounts I suppose.

Live! From CWU! It's Friday at Noon! 😄 Thanks Nick, Hannah and Rachel! Very interesting.

great presentation about the most plentiful element in the universe after hydrogen and helium tu rachel and nick

Very good lecture with clear explanations thank you. Though because i did field work in the desert there while helping my vertebrate zoologist husband i do worry a lot about the environmental impact. There are many slow growing special and rare plant species specifically adapted to various soil types that are variously distributed even in a single valley and animals ( rodents snakes lizards birds predators etc etc) that are dependent on those plants and soil types and each other. The habitats act as islands because of the very old physical relationships and the uneven nature of the distribution of the habitats. So once the area is dug up or disturbed in a major way you basically totally kill everything. Even if you replant many of the plants will die because we don't really know the specific nutrient requirements of the species some of which haven't been even named yet. And the animals in their little "islands * are sometimes in islands thousands of years old and the next nearest matching habitat island may be miles away so small animals can not get to an appropriate habitat.

ARE ALL THESE LITHIUM BATTERIES RENEWABLE? WHAT WILL HAPPEN WHEN ALL THE E-VEHICLES LITHIUM BATTERIES WEAR OUT?

Great talk!

Wow learned so much thank you

Great lecture today. Nick, I'm wondering if the school's IT people might help you out with the network slowdowns. They can check what the load was around noon time. Maybe it's just a temporary thing with limited bandwidth to the RU-vid servers from the school. Or too many students uploading TickTok videos all at once or Facetiming on the school's WiFi network.

I've always heard that most Lithium processing (after mining) occurs in China. Is this still true? One of the obvious questions that comes to mind is that if this supervolcanoe caldera produces Lithium, how much have the other calderas of the progression of the Yellowstone hotspot been explored?

To alleviate the water shortage doing Lithium mining in the west I suggest you form consortiums to pump ocean water back up from the rivers that drain the area in the current drying river beds to the brine lakes of Nevada and desalinate it at the use site or at the coast. a three thousand foot tall water tower would let the fluid flow via gravity.

Watched live, well... listened live. Still, by listening, learned much. As a follower of the move to EV, the lecture provided an important look into the immediate future of the move to electric everything.

Please can you include the chat replay. Nick you are absolutely great!

Looks good here, in Sydney Australia

Great lecture and video as always. Very interesting since the newest and largest deposit was found in the area of the old Yellowstone caldera path.

Well, Nick... It WAS much better to be there 'in person', but I did catch some points on the replay I had missed! Glad it came thru as well as it did. I was on an 'agenda' heading for Colville, so couldn't stick around. Returning home, I did travel thru 'Deer Creek Summit' on Boulder Crk Rd, between US 395 and Curlew, WA and down to Republic.... Awesome GEOLOGY.... But of course, all glacially modified.... LOL I don't think the boulders would be called 'erratics', because they cover 'sq miles', from house size to gravel! With the 'plate' rocks protuding throughout... as well. Fires in recent years have also made it very easy to put 'eyes on' much of what one wouldn't normally see.

What's the price floor which makes mining economical?

i am happy to be a myopic fly on the wall.

Isnt the Atacama a "Placer like deposit'" where locked lakes concentrate the lithium then over time evap maxs the deposit?I wonder if our Pleistocene lakes are placer deposits plus its a lot of clay right .....I also wonder with the Ice Age floods being a silty deposit maybe there are a few slack water deposits

@NickZentner, this is a great talk but the quality is poor. You mentioned that the talk was recorded. Can you please upload the high-quality version as well?

Botanists can help mitigate environmental damage, especialy if involved early in the process.

I wonder what the concentration in seawater is?

It would seem that the ancient path of the (what is now) Yellowstone hotspot would be a good place to look. There were multiple calderas along that path.

max %6 wt in spodumene no longer true, we found way better stuff in Canada. (all I know is pegmatite deposits) there's some evidence in that area that a mixing of chambers in a bimodal system may be critical to substantial Li enrichment. I saw basalt pillows with a felsic barrier right next to Li peggy. Holmquistite in the contact zone, lepidicrosite mica here n there. Our best spod there was near double, up around %11. I cut some of it as a core sampler, holy *F* was it hard! LOL! Cheers!

Save Thacker Pass.

Do lithium miners tend to have a lower rate of psychological depression compared to other miners?

Fantastic Subject & lecturer. Unfortunately video & Sound not as good.😢

Another use for Lithium. 6Li is used in hydrogen bombs.

Great talk, even from Harvard! Union would have been a little better but not much. She's a great presenter. I have mined as a collector/geologist in ME and have found a few Li bearing samples in my time, mostly LI- mica. I wonder if there is ant research into LI there today? Thanks.
