Do Camouflaged Nodes Have A Pattern By Type?

I am asking specifically about ore here but would also be interested if it applies to herbs as well.

In short, do camouflaged nodes follow any kind of pattern for location? For example, I find a LOT of Aqirite ones in the Isle. Note, I also find a LOT of Aqirite camouflaged everywhere, so maybe that is a favored type, period.

Your thoughts appreciated, thanks.
