对铬铁矿成矿作用的研究,是探讨铬铁矿成矿规律的重要内容之一,它不但影响岩体内成矿有利部位的选择(例如,认为铬铁矿是流动分异成矿者,必根据流体力学原理,在弧流、涡流地段开展找矿工作),而且在予测不同岩体的含矿性方面有着十分重要的实际意义。在以往文献中,对于铬元素的迁移(聚集或分散)趋势及其主要原因,以及与铬铁矿成矿密切相关的岩浆分异作用的起因、铬铁矿的形成机制等一系列重要问题,均未作
The study on the chromite mineralization is one of the important aspects to discuss the mineralization rule of chromite. It not only affects the selection of favorable sites for metallogenesis in the rock mass (for example, , According to the principles of fluid mechanics, in the arc flow, eddy current to carry out prospecting work), but also in the determination of different rock mass containing ore has very important practical significance. In the past literature, a series of important issues concerning the tendency of migration (aggregation or dispersion) of chromium and its main causes, as well as the causes of magmatic differentiation and the formation mechanism of chromite closely related to chromite mineralization, None
