在铀矿的找矿和勘探中,研究矿体空间分布条件是一项非常重要的工作。由于找矿和勘探的主要目的是查明矿化带或矿体的展布,因此,这就必须研究矿床在不同形式下受到破坏或保存的条件。一般说来,其表现形式为埋藏于地下、出露于地表或被剥蚀掉。从矿化空间考虑,地质人员必须对上述三种情况有正确判断,否则要对矿区作出远景评价将发生困难。笔者根据岷县礼县地区若干个铀矿床和矿点实例,试想从矿化垂直与水平延展、成矿构造与有利岩性的组合以及剥蚀程度与矿体产状的关系等方面对矿体分布的影响进行分析,然后对矿体空间分布的型式试作初步讨论、至于与铀矿床评价有关的其它地质因素,这里不予涉及。
In the prospecting and exploration of uranium deposits, studying the spatial distribution of ore bodies is a very important task. Since the main purpose of prospecting and exploration is to ascertain the distribution of mineralized zones or ore bodies, it is therefore necessary to study the conditions under which deposits can be destroyed or preserved in different forms. In general, its manifestation is buried in the ground, exposed to the surface or eroded away. From the perspective of mineralization, geologists must correctly judge the above three situations, otherwise it will be difficult to make a long-term evaluation of the mining area. Based on the case of several uranium deposits and ore deposits in the Li County, Min County, the authors try to find out the distribution of ore bodies in terms of the vertical and horizontal mineralization, the combination of metallogenetic structure and favorable lithology, and the relationship between the degree of denudation and the shape of ore bodies Analysis of the impact, and then on the type of ore body spatial distribution tentatively discussed, as for the evaluation of uranium deposits related to other geological factors, not covered here.
