Abstract

The results of long-term studies of the localization conditions, morphology, structure, mineral and chemical compositions of modern ocean sulfide ores, carbonate sediments, as well as ore- and metal-bearing sediments, at 13°–20° N Mid-Atlantic Ridge are summarized. This paper considers the features of sulfide ores formed in various geological and physicochemical environments: (1) on the bottom surface during the hydrothermal solution–seawater (“black smokers”) interaction; (2) under the bottom surface during the hydrothermal solution–biogenic carbonate sediment (hydrothermal-metasomatic ore) interaction. These ore types have some common features, and they are not always distinguished by researchers. A set of distinctive features is proposed to identify the hydrothermal-metasomatic ores that can be used in the search and prediction of sulfide ores in the ocean.

中大西洋硫化矿两种遗传类型的显着特征

摘要

大西洋中部北纬 13°–20°现代海洋硫化矿、碳酸盐沉积物以及含矿和含金属沉积物的定位条件、形态、结构、矿物和化学成分的长期研究结果岭有总结。本文考虑了在各种地质和物理化学环境中形成的硫化矿的特征：（1）在热液溶液-海水（“黑烟”）相互作用过程中的底面；(2) 热液-生物碳酸盐沉积物（热液-交代矿石）相互作用过程中的底面下。这些矿石类型具有一些共同特征，研究人员并不总是能够区分它们。
