Here this REAL LIFE town is the origin of the Name. Just correcting your quote. 
What I suggest is, go with whatever the boarder community uses as a Name, instead of the proper translation. It is a fictional Material and even used in a Factorio Mod I happen to be playing with @OvermindDL1 right now (named “Naquium” there instead), nobody should care that much about the specific Name.
I know that Trinium forms Crystalline Structures similar to Silver/Lead if that is of any help for that Material, but for Naquadah I honestly dont know what its raw Mineral state is, it might be Quartz-ish, but that is the closest guess I can give.
