Also known as “Cobalt Bloom,” #erythrite forms from the weathering of other cobalt-bearing minerals. Typically found in the oxidized zone of cobalt-nickel-arsenic ☠️ deposits. Link in ALT! #MinCup26 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology #geosky #GIS 🍎 🪐 🔭 🌋 📚 🌿

‘Sphalerite, when found in gem-quality crystals exhibits a dispersion three times higher than that of diamond. This high dispersion means that light entering the stone is split into a rainbow of colors.” 👀 ALT #MinCup26 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology #geosky #GIS 🍎 🪐 🔭 🌋 📚 🌿

For the German election we wanted to use a cartogram of German election districts but didn't find anything good, so we created our own. Here's a little nerd thread how the final algorithm worked 🤓 🧵 #gis #cartogram #election #datavis #cartography

Cartogram of 299 German election districts

Hopper crystals form when the outer edges of a crystal grow much faster than the center of its faces, creating a hollow, stepped, or staircase-like skeletal structure. More at: www.geologyin.com/2019/06…. #MinCup26 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology #geosky #GIS 🍎 🪐 🔭 🌋 📚 🌿

Remember calcite was knocked out by julienite and vote accordingly 😈! #RevengeVote 😆 #MinCup26 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology #geosky #GIS 🍎 🪐 🔭 🌋 📚 🌿

AUSTRALIA and beyond - We need to assemble again for #Putnisite! This amazing structure needs your support in today's #MinCup26 battle. For shear density and novelty in its strange/wonderful crystal structure it should get your vote over #Julienite

Image representing the crystal structure of putnisite - here red spheres represent oxygen atoms, light blue spheres/polygons represent calcium atoms, dark blue spheres/polygons represent silicon atoms, brown spheres/polygons represent carbon atoms, green spheres/polygons represent strontium atoms. There is also some chromium hiding in the structure that is in part represented by a yellow triangle. The representation is drawn in VESTA from entry #20044 in the American mineralogist database

Image representing the crystal structure of julienite - here red spheres represent oxygen atoms, dark yellow spheres/polygons represent sodium atoms, dark blue spheres/polygons represent cobalt atoms, yellow spheres represent sulfur atoms, brown spheres represent carbon atoms and light blue spheres represent nitrogen atoms. The structure is viewed down its c axis and shows that there are sodium/water(oxygen) units surrounded by cobalt complexes with nitrogen, carbon and sulfur attached. The representation is drawn in VESTA from entry #9760 in the American mineralogist database

You can use this UN-approved Equal Earth projection right now in #rstats #gis #databs

library(tidyverse)
library(sf)
library(rnaturalearth)

world <- ne_countries() |> filter(sov_a3 != "ATA")

ggplot(data = world) +
geom_sf() +
coord_sf(crs = "+proj=eqearth") +
theme_void()

A basic world map using the Equal Earth projection

CNN @cnn.com

The United Nations General Assembly voted to adopt a new world map that reflects countries’ true relative sizes, after African nations urged the UN to right a centuries-old wrong.

#Quartz! It can be anywhere! It forms and thrives in all three rock types. It grows protective covers over soft minerals. There are so many varieties, colors, shapes, sizes, textures. It does fun things like create a charge if heated or stressed. Smash it and it glows! Vote #Quartz! #MinCup26

Widgiemooltha is a 1897 historic town in Western Australia’s goldfields that arose during the gold rush, & was named the aboriginal name for a nearby hill. This pretty purple putnisite crystal was found there. This mineral has a completely unique chemical structure found nowhere else in nature.

This tiny purple putnisite crystal is from the Armstrong Ni Mine, Widgiemooltha, Coolgardie Shire, Western Australia, Australia. It is unique in chemistry and nature, and found nowhere else. From Mindat: https://www.mindat.org/photo-543393.html

A small but beautiful gem quality golden terminated #andalusite that deserves your vote. Today I am voting for a mineral that didn’t get eliminated (unlike yesterday, DOH!) Progress 😆 #MinCup26 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology #geosky #GIS 🍎 🪐 🔭 🌋 📚 🌿

Since the minerals, liquids, and gases are well protected from chemical alteration, #quartz inclusions open a window to the past that can help scientists reconstruct the chemical and physical conditions that existed when the rock formed.

This bubble is in liquid inside of a negative crystal which is in a quartz cabochon host. In other words, a two-phase inclusion that happens to be in a negative crystal. (Photos: Wimon Manorotkul)
