The metal-bearing solutions which filled clefts and fissures in the porphyrites, creating the ore veins, percolated also into the most narrow openings, forming impregnation zones characterized not by discrete veins but by dense "nests" of stringers and pods (Trumem), and causing some brecciation of the porphyrite.
