绝大部分超基性岩岩体的最大特点之一是岩体的非均质性,这种非均质性也是成岩期所产生的构造要素。对超基性岩中的铬铁矿床来讲,是岩浆期的产物。因此对超基性岩体内部构造进行研究,并进一步探讨其对矿床的生因与控制作用时,势必应对岩体成岩前、成岩期和成岩后各个历史阶段加以区分。各阶段所生成的构造形迹必具有特定的模式,它体现着那些阶段应力场的强弱和性质。随着岩体的演变,岩体的应力场可以发生一系列的
One of the most prominent features of the vast majority of ultrabasic rock masses is the heterogeneity of the rock mass. This heterogeneity is also the structural element of the diagenetic period. For the chromite in ultrabasic rocks, it is the product of magmatic stage. Therefore, when studying the internal structure of ultramafic rocks and further exploring the genesis and controlling effect of the orebodies, it is bound to make a distinction between various historical stages after diagenesis, diagenesis and diagenesis of the rock mass. The structural traces generated in each phase must have a specific pattern that reflects the strength and nature of the stress fields in those phases. With the evolution of rock mass, the stress field of rock mass can occur a series of
