一、岩带内岩体含矿性的评价超基性及基性岩体一般均沿深大断裂侵入,形成大小不等的几十个甚至几百个岩体构成岩带.由于元素在这些岩体的原始岩浆中分布的不均匀性和岩浆的深部分异作用,形成了化学成份不同的超基性岩体和基性岩体,而各个岩体的含矿程度(Cr、Ni、Co、Pt等矿床)也各不相同.在这么多岩体面前,首先应该指出哪些岩体可能含矿?含什么矿?这在大面积普查找矿阶段是一个很重要的实际问题.实践证明,应用岩石地球化学特征配合其他地质方法就可能提供评价岩体含矿性的资
1. Evaluation of ore-bearing property of rock mass in the rock belt The ultrabasic and basic rock mass invade along the deep faults in general and form tens of or even hundreds of rock masses of unequal sizes to form rock belt. Because of the elements in these The heterogeneity of distribution in the original magma of the rock mass and the deep differential differentiation of the magma formed ultramafic rocks and basic rock bodies with different chemical compositions. The ore-bearing degree of each rock mass (Cr, Ni, Co , Pt and other deposits) are also different.Among so many rock mass, we should first indicate which rock mass may contain ore and what kind of ore are contained.It is a very important practical problem in large-scale general prospecting stage.Practice has proved that, The application of geochemical characteristics of rocks in combination with other geological methods may provide information to evaluate the ore-bearing properties
