What mod adds the large ore veins?

I'd like to know which of the millions of mods in this mod pack adds the huge ore veins of like 30 iron (or anything)  that you can find.  I will forever love the person who can tell me.  Thank you!

Attack of the b team is good for that

Team CoFH (devs of Thermal Expansion) adds this feature that can be changed in the config files.
