That means geological surveys and drilling on the surface. I'm reasonably confident enough is there. Known Earth reserves of minerals always magically increase when existing mines run out. So even on Earth there's a lot more acidspar out there. And lower grades are still usable with a bit more effort. The issue is making the GHGs in-situ. | |
| Apr 7 at 17:15 | comment | added | Galerita | Thanks Cornelis. I'll re-read it. Here's another paper I just found, "Fluorine in the bulk composition of Mars has been estimated at 32 ppm vs 19.4 ppm for the Earth". pnas.org/doi/full/10.1073/pnas.051511598 Still more on Mars. I remain convinced the problem is manufacturing fluorocarbons & SF6, not finding fluorite. I can't find research on this. As you know, I've partially explored it here space.stackexchange.com/a/65779/54582 & here chemistry.stackexchange.com/questions/181813/… | |
| Apr 7 at 15:50 | comment | added | Cornelis | Another extensive answer, thank you ! I must say, I have my doubts about your presumed relative high surface concentrations of fluorite on Mars. Please read the first alinea of the Discussion paragraph of the linked research letter. I got the idea that the conglomerates wherein the F bearing minerals were found, represent a quite unique environment likely related to magmatism around the crater rim of Gale. | |
