Interpretation of Mineral Zoning in Submarine

siliceous ore is rich in quartz but poor in barite, although barite veinlets that formed later than the sili-ceous ore occur in this zone. Barite is abundant in both the black ore and barite ore. It is also found in ferrugi-nous chert ore (Kalogeropoulos Scott, 1983). Quartz does not exist in large amounts in massive sulfide ores
