Lode
The term used for an ore-producing vein. Ore occurs in either beds or mineral veins; in the latter the veins are invariably found to have one of two or three principal directions, being either nearly parallel to the axis of elevation of the district, at right angles to that direction, or at an angle of 45 deg. with it. The first are right-running lodes; the second, cross-courses; and the third, contra-lodes, or counters. See ORE; VEINS.
