为探讨硫化物熔离对含矿岩体中橄榄石Ni含量的影响,在前人橄榄石结晶硫化物熔离模型的基础上,定量模似计算了分离结晶过程中橄榄石Ni含量,并将其应用于金川橄榄石成因研究.研究表明,部分橄榄石落于无硫化物熔离橄榄石结晶趋势线下方,暗示其母岩浆为S饱和.根据模拟计算S饱和母岩浆橄榄石分离结晶趋势线,指出金川深部岩浆房中母岩浆橄榄石的分离结晶程度小于或等于3%,而由橄榄石结晶所导致熔离的硫化物熔体与橄榄石之间质量比约为40. |

In light of former model of olivine fractionation and sulfide molten from magma,we simulated magma differentiation in the processes olivine separation and sulfide molten from silicate magma,and studied the effect of sulfide separation to Ni content in olivine,and studied the genesis of Jinchuan olivine.The results showed that parts of Jinchuan olivine components located below the fractional crystallization line of olivine with no sulfide separation,indicating the parental magma of Jinchuan olivine is sulfide-saturated.By elaborated analyzing the simulation of fractional crystallization line of olivine with sulfide separation,we believed less than 3%(wt) fractional crystallization of olivine was separated from magma and believed the mass ratio of sulfide removed from silicate magma to olivine was about 40 in a staging magma chamber. |
