地质勘探工作方法比较完善的地区,矿区的开发和理论的研究都表明了:在普查评价阶段和随后的初勘阶段,研究的主要对象不应该是单个的矿体和矿段,甚至也不是单个的矿床,而应该是更大的金属成矿单元——矿田。为了揭示每个矿田的最重要特征,对每个大型金属成矿省中的矿田进行对比研究并找出它们的标型特征是地质勘探工作者的迫切任务。 Geological exploration work is relatively well developed areas, mining area development and theoretical studies have shown that: in the census evaluation stage and the subsequent preliminary exploration stage, the main object of the study should not be a single ore body and ore section, or even a single Of the deposit, but should be a larger metal mineralization unit - ore field. In order to reveal the most important characteristics of each ore field, it is an urgent task for geologists to conduct a comparative study of the ore fields in each large metallogenic province and find out their typological features.
