#MinCup24 R4M1: #Perovskite versus #Rhodochrosite

Perovskite has a flair for high-profile environments, found in the rain in brown dwarf stars, in volcanic fumaroles, and in kimberlite pipes rocketing from mantle to crust. Rhodochrosite’s crystals can be the palest blush to the darkest blood red, and can form rhombohedral and scalenohedral crystals, rosettes, blades, and massive and botryoidal crystals

#MinCup24 It's got to be #quartz. So much more scientifically useful and interesting. And passes my personal highest bar of importance: USED FOR X-RAY SCIENCE! Single crystal quartz can be used to select or filter specific wavelengths of X-rays -- in this application it's known as an analyzer (ncbi.nlm.nih.gov/pmc/articles/). A variation using different materials but the same physics was critical to my PhD work (ncbi.nlm.nih.gov/pmc/articles/).

Besides, #rhodochrosite isn't even the best meat rock! That would be en.m.wikipedia.org/wiki/Meat-S.

#MinCup24 R2M4: #Rhodochrosite versus #Quartz

Rhodochrosite began Mineral Cup 24 to the rallying cries of “Meat rock, meat rock.” Will voters once again sink their teeth into this appetizing rose-colored delight? Or will quartz’s resistance, piezoelectricity, and myriad of varieties, colours, and forms, weather this battle to continue to the next round?
