Recent laboratory experiments and chemical modeling of iron meteorite crystallization reveal that the earliest planetary bodies (planetesimals) possessed distinct nitrogen and phosphorus ratios, reshaping our understanding of how life-essential elements were distributed in the young solar system.

#Venus doesn't have much (if any) #calcite, no limestone, and little if any other carbonates.

Those carbonates instead are CO2 in Venus' atmosphere -over 90 times our atmospheric pressure. This gives Venus a surface temperature of 475°C.

Poor Venus.

Calcite for a habitable planet!

Some #corundum on Earth is older than our solar-system; these pre-solar grains are found in some chondritic meteorites. Oxygen isotopes reveal that they formed in the puffed-off atmospheres of old red-giant stars. From Frisch et al. 2005.

We have #Moissanite crystals that formed in other stars! Dissolve some meteorites almost completely, and some of the residue is SiC -these grains have carbon and silicon isotopes produced in red giant stars and supernova; from before our solar system formed. See Larry Nittler's (now at Arizona State University #ASU) presentation:

How do you abbreviate "weight percent"?

And if you can, please provide me with a link to a style guide that motivates your choice!
