【摘要】 从赋矿岩体、控矿因素、成矿作用和矿体类型等方面综述了铜镍硫化物矿床的最新研究进展和成果。认为赋矿岩体由镁铁质—超镁铁质的不同岩石组成,其锶同位素组成显示深源的特点;岩浆的深部熔离作用使岩体的出露大小与矿床规模没有正相关性;成矿界面主要有岩性组合界面、构造界面、构造物理—化学界面和构造流体界面等,它们严格控制成矿物质的最终定位;除岩浆熔离和结晶分异成矿作用外,成矿作用强调厂硫化作用、热液成矿作用和接触交代成矿作用,相应的形成了热液型矿体和矽卡岩型矿体。更多还原

【Abstract】 The study development of Cu-Ni sulfide deposit is discussed according to the ore-bearing rock-bodies, ore-controlling factors, mineralization and deposit types. It shows that ore-bearing rock-bodies are made up of different mafic and super-mafic rocks and their Sr isotope implies and their deep origin; because of its deep differentiation by liquation, the deposit scale isn’t positive correlation with the outlet size of rock-body; ore-forming interfaces, including lithological association interface, tectonic interface, tectonic physical-chemical interface and tectonic fluid interface, strictly control the final location of ore-forming materials; except magmatic liquation and crystallization differentiation, it includes sulfurization, hydatogenesis and contact metasomatism; as a result, hydrothermal type ore body and skarn type ore body are formed.更多还原
