419:. Native aluminium cannot. That is a more significant distinction at that level than the distinction between "all elements ever identified by microscope" and "all elements". What about zinc? Or carborundum? Zinc is listed on mindat from specks found at a mine site, which I strongly suspect was a smelter. The rainbow-hued acicular carborundum beloved of rock shows is known from depositions on the inside of smokestacks, not the natural world. If these are in, then what isn't there? Marie Curie's drainpipes could probably turn up a spot of radium if we looked closely enough - is that going to be a "native element" mineral too?

Oxygen bearing minerals are silicates (N/S identifier #9) or sulfites (N/S identifier #4.JE.) or carbonates (N/S identifier #5) or nitrates (N/S identifier #5.N) or borates (N/S identifier #6) or sulfates (N/S identifier #7) or phosphates (N/S identifier #8) or oxyhalides (N/S identifier #3.D).

Mostly I'm concerned about elements being categorized here without being explained in the text. A century of RS geology textbooks will say "aluminium or titanium are not found in native masses". If we are to contradict that, we have to do it with some clarity. If something is only findable by

Firstly, "It can be found" is not the same as sourcing it, per WP:BURDEN. Nor are noting broad website homepages in an edit summary the same thing as citing challenged content on the page. These are exceptional claims, per WP:V. They

If we accept that the existence of any elemental mineral, no matter how obscure or how tiny a quantity of it exists, then how is that category distinct from the periodic table? Native copper can be found and worked
