That will start to get into questions about carbon in the mantle and in subduction that I don't think there's enough petrology done for yet....
Actually, there are still a lot for volcanology, but just in disguise with names like 'Earth Materials' alongside igneous petrology, etc.
Indeed I love it! I’m now in third place in moving on your map! 🥉 🌋 if your still active, I sent a friend request on GeoGuessr I’m SpinifexTexture which is an excellent choice for a volcano igneous petrology person. 😁🌋
(I don't think what we know about mantle transition zone petrology is consistent with the 660 discontinuity being forced downward that far and there *is* a set of mineral phase changes that should occur near 720 km....) This is a generic mantle question, basically.
Hard rock petrology and later half 18th century France, and American colonial period.
Hear me out: an igneous petrology journal called the Magma Carta
Geology students with arm loads of cheese, prosciutto and exotic crackers to go munch in the petrology lab over our microscopes. Those were good days 😁
