Use prospect and check it. If you have ores cranked to the max, flux will not show up on the list, but if you prospect, it is there. Look for marble, limestone, and dolomite.
Wait, so you CAN do that before embarking? For some reason I thought it was only after embarking.
Anyway it occurs to me that I could just use bone and import limestone.
I have other problems anyway. I embarked on the only location on the map that has everything except flux (haven't prospected for that yet, might be there).
Even a volcano and a river.
Turns out one of my original settlers was not only a miners guild member... he was also completely insane. Schizophrenic no less. He attacked my other guys and was killed about 5 minutes after embarking. Thanks a lot game!
And then the badger dog pups I brought with me went berserk and although I don't think they actually attacked anyone, they were interrupting all the jobs. I don't understand why. Even the dead schizophrenic guy was interrupting jobs according to the log. After he was dead!
Is that just the log lagging behind the game progress, or what?
Anyway should I just avoid taking badger dogs? Or are they OK (i.e. Don't interrupt every dwarf nearby) once war trained?
