@The_Jow It would seem we share a birthday, happy birthday Simon

It’s a coal mine. What grade, tonnage and recover of rare earths are you expecting, @ENERGY? Perhaps quantify this rather than just stating nothing at all.

[Erik Haroldson @erikharold]

@NickDygert How are you obtaining samples? I must have missed that tweet. Bucket dredging?

*Geology PhD alert!* I'm looking for a curious, enthusiastic student to work on critical metals in remobilized sulphides, at the University of British Columbia - Okanagan campus in Canada. Please apply by 1 Dec. More info here: https://t.co/knuEIXY62Y

I knew there were a lot of fake accounts on this platform, but they are usually obvious. I had no idea how intricate and complex the ruse could be.

Get a load of this story.

Agreed! That's why I wrote ggpubfigs, a ggplot2 extension that *only colorblind-friendly color palettes.

Easily make your figures colorblind-friendly with ggpubfigs! https://t.co/frQgsl7zjP

@NickDygert @UTK_EEPS One of my fav demos. The doc cams at APSU had a built in light table. This semester at CSUS I had to use an old projector. However, I recently spotted a light table tucked away in a closet. So I'll be doing a setup like in the video going forward.

[Erik Haroldson @erikharold]

@KathyBenison Yes, that was a great trip you said to talk to Jim. It's in fact why I now have to make this decision.

Fluid Inclusion folks (I know this will get a lot of hits). I've only worked with Linkam stages, but always intrigued by the USGS gas-flow. Alas, at my new gig I have funds but for only one of them. Which way should I go? #geotwitter

[Erik Haroldson @erikharold]

@Delta18O I'm interested in offering such a thing. Research focused adjunct?

A few minutes ago, Unit 4 turbo-generator at Ratcliffe-on-Soar power station desynced from the GB grid system, marking the END of electricity generation from COAL after 142 years 🇬🇧🙏🏻 @RobBurnett92 and I present a 🪡🧵on the evolution of coal fired power from 1882 to today 1/n

How do I express that I’m concerned about the people of western NC and I’m also concerned about the potential future global economic disaster because Spruce Pine is the sole producer of ultra pure Quartz for crucibles that all global semiconductor production relies on?

Massive debris flow traveling at lightning speed in eastern TN! The preceding drought conditions followed by days of rain ahead of Hurricane Helene set the stage. This is incredibly rapid for a debris flow.
