石英脉型金矿是我国重要的金矿类型之一,在黔东南和湘西一带分布十分广泛。但此类矿床的变化大,评价和勘探十分困难,常需投入大量的工作,稍有不慎就会落空,造成人力和物力的浪费。因此,如何在少量地表地质工作的条件下,就能较准确地预测矿脉的规模,选准评价和勘探对象,以提高经济效益,是地质工作中一个急待解决的问题。基此,我们尝试以逻辑信息法,研究黔东南地区该类型金矿的评价模型(或预测模型),以期为预测矿脉的可能规模提供一些信息,为选准对象提供一些帮助。
Quartz vein type gold deposit is one of the important gold types in our country, and it is widely distributed in southeastern Guizhou and western Hunan. However, the change of such deposits is quite large, evaluation and exploration are very difficult, and often require a lot of work to be done, resulting in loss of manpower and material resources due to a slight mistake. Therefore, how to accurately predict the size of ore veins, select criteria for evaluation and explore targets to improve economic benefits under the condition of a small amount of surface geological work is an urgent problem to be solved in geological work. Based on this, we try to study the evaluation model (or prediction model) of this type of gold mines in Southeast Guizhou with logic information method in order to provide some information for the prediction of the possible size of the ore veins, and to provide some help for the target selection.
