Abstract
Ferrocarpholite has been discovered at two localities in low-grade blueschists in the Diahot region, northern New Caledonia. In one occurrence (specimen 23503), ferrocarpholite was found in quartz veins associated with metamorphosed rhyolitic tufts, and at the other locality (23514) it occurs as a gangue mineral at Ao Mine associated with quartz, a variety of carbonates, and sulphide ores.
