Want an early start to #MinCup23? Read Howard Lee’s great article about U-Pb dating of zircons, and use of magnetic data to find out how surprisingly fast the Pilbara Craton was moving 2.7 billion-years ago. This incredible usefulness is why zircon is called the Time Lord. Expect more Time Lord soon

So apparently the flight from Twitter means #MineralCup (does # work here?) is now a website! It will be different but it’s still MineralCup! Try out the new polling system over at: mineralcup.org the upshot is that even more people can participate!!
