Antimony hardens the lead and prevents shrinkage and deformation when the alloy cools from a melt in a mould to make the moveable type. It meant that high quality clear text could be repeatably printed on mass unlike previous printing that used carved wood blocks that deteriorated quickly /3
Vote #Stibnite (Sb₂S₃) for #Mincup25 ⚒️🧪 because it was the likely source of antimony that literally wrote history. The chemical symbol for antimony is ‘Sb’ from ‘stibium’ the Latin for, you guessed it, #stibnite. Let's revisit a 🧵 from last year /1 buff.ly/md0dreE
Spectacular strata and landscapes of the Tethyan Himalaya captured from a Delhi Leh flight last week. Pics- Sudheer Palsane.
Even 15 years later, I remember how impressed I was by this massive stibnite specimen in the American Museum of Natural History in New York. A very Fortress of Solitude/crown of the Witch King aesthetic with all those interlocking columns. #MinCup25

Hi #geosky, it’s been a minute. Where can I find the latest trends and techniques in geologic map making? How are undergraduates learning to map - on paper or using digital techniques? If digital, what tools are prevalent and who are the leading experts/researchers in this area? TY! #geology #maps
We present from the Lower Vindhyan Group, for the 𝗙𝗜𝗥𝗦𝗧 𝗧𝗜𝗠𝗘, compelling field evidence like buckle folds, reverse faults, and pop-up structures, commonly encountered in fold-thrust belts, that unambiguously support their collisional origin as opposed to the largely believed syn-sedimentary origin.

Losing the JR was a huge blow. I think especially because of that an NSF budget with the Palmer cut wouldn't have happened in normal times. The Palmer was expected to continue until we were closer to getting the replacement. Now we are losing every Antarctic research ship & likely the replacement.

Just a reminder that #IsleofWight isn’t all about the Cretaceous but also has terrestrial deposits from the Eocene and Oligocene with some fabulous insect and mammal fossils. For #FossilFriday a coprolite in its matrix. Probably a croc and I’d guess the lower bit came out last. A lovey find.
Mind-blowing: the Grand Canyon has a single primary water source: a fragile spring near the bottom of the canyon. Water has to be pumped up ~3K feet to the rim and gets around via an old system of "creative" pipes. Photos via the National Park Service.
