Controls on the Formation of Komatiite-Associated Nickel-Copper Sulfide Depositslevel magma chambers, but there are several field, physical, and thermodynamic constraints which suggest that this may not be feasible: (1) the spatial concentration of mineralization within certain pans of otherwise virtually barren host units suggests that the latter were not uniformly saturated i

Depositional Environments of Volcanic Peridotite-Associated Nickel Sulphide Deposits with Special Reacterized by thicker more-magnesian basal ultramafic flows, fewer interflow metasediments and better textural development and compositional differentiation in overlying thin flow units. The ultramafic sequence overlying ore environments is generally less ordered than that in adjacent non-ore environ

Types and Distinctive Features of Ore-Bearing Formations of Copper-Nickel Depositsbetween the morphology of intrusive bodies and their ore potential is observed. Ore-bearing magmatic bodies are typically elongated, band-chonolitelike bodies with flat roofs and downwarped bottoms; this is attributed to the excess of density of ore-bearing magmas over that of environment (at the ex

Batholith-Volcano Coupling in the Metallogeny of Porphyry Copper Depositse interior of the batholith becomes buoyant and intrudes the upper part. The early batholith forms a broad, gentle dome intruded by later domes. The process is repeated with buoyant upwelling of the interior of the intrusive domes forming cupolas, some of which breach the surface and form cones or s

Metallogenic Zoning of Volcano-Plutonic Belts and Porphyry-Copper Mineralization, Sn—W, W—Mo, W, Au—Ag ores. The metallogenic style of the VPB is determined by the formation of porphyry deposits. The metallogenic zoning of the VPB is exemplified in some provinces of the Soviet Union.
