@silvercoveltd.bsky.socialWhen lightning leaves a fossil behind.
#Fulgurite forms when #lightning strikes sand or soil, creating temperatures intense enough to rapidly melt and fuse the material. The result is a fragile, glassy tube that preserves the path of the electrical discharge through the ground.

@mexporg.bsky.socialMonster size faceted #Calcite from Brazil - 1800 ct!!!
Calcite is very difficult to facet due to its perfect cleavage and very low hardness.

@brjournal.bsky.socialMore #mineral does not always make #bone stronger. In mice with high bone mass #osteogenesis imperfecta, abnormal collagen processing disrupted the bone matrix, producing thinner, poorly aligned mineral particles and bones that were highly mineralized but extremely brittle.👇

@naturaelapides.bsky.socialDespite a fine comeback, Gypsum were defeated; such is the glorious unpredictability of sport!
Now it’s the turn of another giant: calcite – vote for it!
Don’t let yourself be moved by the heart-wrenching story of Julienite.

@naturaelapides.bsky.socialCome on, Gypsum, you can do it #TeamGypsum!
A fascinating mineral – and it’s fluorescent too!

@catwithgeologists.bsky.socialToday it's #Gypsum against #Pyromorphite at #MinCup26 😻 Look this pawsome lake in #Switzerland was formed because the #mineral gypsum can form #karst 😻 Thus thanks to gypsum Simbalito could have this Pawsome subsurface adventure 😻
#DoesItCat ? Yes🐾

@catwithgeologists.bsky.socialIn today's #MinCup26 duell it is #Hafnon against #Putnisite we didn't know either of them, but we see that the #mineral Hafnon has a simple formula Hf[SiO4]. Just simple enough for our humans😽 and that it is the only known mineral with #Hafnium as main ingredient🙀
#DoesItCat ? Yes🐾

@catwithgeologists.bsky.socialToday it's #Talc against #Stichtite at #MinCup26 😻 This is easy for us Talc is representating the fluffy end of the Moths scale that measures the hardness of a #mineral 🙀😹
Being fluffy is one of the supaw powers of #cats
