Obvious question: What about other, non-marble crystalline material? You cannot make quartz or diamond more crystaline than they already are!

This is the discussion related to the wiki page SCP-409.
Obvious answer: the quartz gains SCP-409's contagious abilities, and the diamond turns into quartz.
You know, I just had a thought. Affected objects shatter into fragments after complete transformation. What if this is only a fragment of something very, very large? A planet, for example.
Okay, obviously this doesn't affect gaseous substances or it would have long since destroyed our atmosphere.
Hm.
How does it affect liquids?
I have this notion that this was a created thing, and that the reason it doesn't affect granite is because granite was the hardest substance its creator knew. Like with how SCP-107 produces H2O when given D2O, because its creator was completely ignorant of the concept of isotopes.
The interesting thing is that granite often has quartz as an ingredient.
Hmmm.
What if we blast this thing with streams of ultra-high-pressure water containing powdered granite? (I know, I know - we're not the GOC. We don't try to destroy these things by default. But it's an idea.)
The thing about liquids and gases makes me wonder, now… can it affect a block of dry ice? Or water ice, for that matter?
Hmm. Perhaps containment measures should include something about very hot water. It can't convert H2O into SiO2 as long as the H2O is still liquid…
Actually, I think attempts at destroying SCP-409 would be warranted, if only so you don't need to keep carving out granite coffins. Blasting it with powdered granite, though, would probably just cover the area in minute shavings of deadly crystal, which might be considered counterproductive.
I'd like this entry more if it actually implied that the granite was a weakness for that reason, or if it implied that the granite was created. Right now, the Superman joke in this thread seems apt; granite is just randomly this object's kryptonite.
If someone comes into contact with it, what's to stop them from going nuts and touching, say, the ground?
Nothing, but remember, it only spreads so far on non-organic substances.
You keep using that word… "organic".
I do not think it means what you think it means.
(What do you think topsoil is made of anyway?)
Granite is not a mineral; rather, it is a rock of varying composition. If granite is immune, then so is quartz, alkali feldspar, plagioclase feldspar, and all the other minerals commonly found within granite, such as mica. If pure minerals would change into a contagious version and be capable of spreading a few centimeters, then the entire block of granite would do the same.
Is there something about the fact that the three main minerals are together that stops it? There's no mention of tests with minerals or with rocks on the sides of the spectrum (like monzonite or tonalite) that would primarily have just two of the three. Without such a note, it doesn't feel convincing that only granite would work.
This was bugging me, too. Granite is a mixture of a bunch of different kinds of rock, AND there's lots of different kinds of granite.
