在许多国家,内生矿床中的金矿床是以最深的矿井进行开采的。许多矿床的上部中段和中部中段的矿体已被采尽,目前正着手解决深部中段金矿储量的评价问题。现有资料的分析表明,并非所有的金矿床类型都是以矿化垂直延展距离大为特征的。但是据查明,就是在这方面具有远景的类型中,也只有个别矿体才具有从现代的古地表至1公里和大于1公里深的连续(或近于连续)矿化。在这些称为“深延矿床”中,多数拥有巨型和特大型的金储量。 查明国外深延矿床特有的地质特点,对于有目的地寻找有远景类型的矿床、予测评价矿化向深部的可能延深以及在新的和已知的金矿区的勘探设计中选择最佳方案都是非常重要的。总结深延矿床在矿化分带
In many countries, gold deposits in endogenic deposits are mined in the deepest mines. Many ore deposits have been exhausted from the upper middle and middle parts of the ore body and are currently addressing the issue of assessment of gold reserves in the deep middle section. Analysis of available data shows that not all gold deposit types are characterized by large mineralization vertical spreading distances. However, it has been ascertained that, of the types of prospects in this respect, only a few individual ore bodies have continuous (or near continuous) mineralization from modern paleo-land to 1 km and greater than 1 km deep. In these so-called “deep extension deposits,” most have large and very large gold reserves. To identify the geological features unique to the deep-seated deposits overseas, it is of great importance to find the prospectively-typed deposits purposely for the purpose of assessing the possible deepening of mineralization to the deepest and for the exploration design of new and known gold mines Good program is very important. Summarize deep Yan ore deposit in mineralization zone
