Erin 𓅉 @getpseudoed.bsky.social · 11/09/2023If you find yourself intrigued by calcite crystallography, I strongly recommend browsing Goldschmidt’s Atlas Der Krystallformen, which has 150 pages of this. Available to view here (log-in is required to view the PDF - but an account is free and easy!): www.mindat.org/reference.ph... 182
Reposted by Erin 𓅉Mika McKinnon @mikamckinnon.bsky.social · 10/05/2023When evaluating rocks for personal use, it’s not just about shape (although that better be gratifying). Texture, strength, hardness, solubility (in water & acid) are all important considerations, occasionally along with more obscure characteristics like smell or stability under surface conditions. 1013448
Erin 𓅉 @getpseudoed.bsky.social · 10/09/2023My vote is for #adamite because of the adamite bat. The bat is largely mummified but adamite has started to replace around its face - fluorescent light highlights the adamite. Found by John Seibel, late 1980s at the Gold Hill Mine, Utah, collection of Mark Mitterman. 36021
Erin 𓅉 @getpseudoed.bsky.social · 07/09/2023I’m pretty ambivalent here but I’m gonna vote for #vivianite solely because of this excellent (and amusing) article, “A Scientific Study of the Absorption of Evil by Vivianite” by Alfredo Petrov: www.mindat.org/article.php/... 5185
Erin 𓅉 @getpseudoed.bsky.social · 06/09/2023This round is going to break my heart because #goethite is the only mineral in the bracket I REALLY like, and it’s going to get beat out by a mineral I can’t see. Vote #goethite to make me wrong, and thus happy. 🥺 1143

Erin 𓅉 @getpseudoed.bsky.social · 05/09/2023Crocoite has an unusually frequent tendency to grow into such crystals so extremely hoppered that the crystals are HOLLOW. Orange lead-chromium straws does it perfectly for me. 🥰 #TeamCrocoite #MinCup23 www.mindat.org/photo-219055... 081
Erin 𓅉 @getpseudoed.bsky.social · 04/09/2023This is what happens when stibnite “rusts.” I had to unpack a backpack full of rocks for the TSA over this specimen once, and the man was so, so very disappointed when we opened the box and I’m still laughing about it. 1175
Reposted by Erin 𓅉Vicky Veritas @vickyveritas.bsky.social · 17/08/2023Want 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 2176
Erin 𓅉 @getpseudoed.bsky.social · 03/09/2023One of my favorite things, for being so plain but so incredibly cool: the oldest mineral yet found. Jack Hills zircons have been dated to ~4.4 billion years ago. They were formed during the Hadean (all of earth was more-or-less molten), then cycled into sedimentary grains. #MinCup #TeamZircon 1169
Erin 𓅉 @getpseudoed.bsky.social · 02/09/2023I waffled because cinnabar is neat, but the pseudocubic habit of quartz might just be my favorite crystal habit, and the very best are found in New Mexico. 😍 www.mindat.org/photo-280989...mindat.orgQuartz (Var: Pseudocubic Quartz), Quartz (Var: Pecos Diamonds)"Pecos Diamonds" are quartz crystals that are found along the Pecos River valley, either weathered out of or still inside a selenite rock matrix of the Permian Seven Rivers formation in south-eastern ... 011
Erin 𓅉 @getpseudoed.bsky.social · 02/09/2023Oh, also, cinnabar isn’t toxic. Containing an element that is harmful does not make a mineral harmful. This is a matter of bioavailability - whether the body can absorb any of the harmful element. Largely this boils down to solubility, and cinnabar isn’t very soluble. #MinCup23 183

Erin 𓅉 @getpseudoed.bsky.social · 01/09/2023An argument for clay mineral kaolinite: one of mindat’s very best Easter eggs. When @jolyon.bsky.social added the pronunciation feature, he also added a ton of the pronunciations himself. He got bored somewhere in that process. “Clay” is one of the best - go listen: mindat.org/min-49430.html 393
