【摘要】：随着近年来我国现代化进程的加快,国民经济和社会发展对矿产资源需求量保持上升趋势。并且随着露头矿、半露头矿和浅层矿等已日见稀少,覆盖区找矿已经成为地质勘查工作的重点。而常规化探方法对于埋藏较深的矿床找矿效果不好,因此,地气测量研究以及土壤活动态提取技术越来越受到重视。本文工作区位于红壤覆盖区的江西塔前-朱溪-赋春铜多金属成矿带,矿床都是典型的隐伏矿床,至今还处于勘查阶段,尚无采矿污染,是展开地气测量和土壤活动态提取试验及其他化探方法勘查试验较理想的地区。通过对朱溪钨铜矿区和月形铜矿区展开了地气测量勘查有效性试验研究,有效性试验性结果表明,不同矿区效果差异比较大,在朱溪矿区,由于大范围碳酸盐地层的存在,可能限制了地气组分的迁移,地气中元素含量都比较低,对隐伏矿床指示效果较差;而在月形矿区,地气异常在隐伏矿上方有着清晰、连续的异常,对隐伏矿体指示效果很好,能够提供有用的找矿信息。在朱溪钨铜矿区同时进行了土壤活动态提取技术的研究,本文选择了B-试剂作为提取剂,进行了不同浓度、不同提取方法实验研究,并与常规土壤全量进行对比。从实验结果来看,活动态提取方法能够获得比常规土壤测量更多指示隐伏矿的信息。0.2%浓度比0.5%浓度的试剂能够提供了更多可能,动态提取比静态提取方法更能够获得部分来自深部矿化信息。本论文旨通过对不同矿区的勘查地球化学方法研究以及对同一个矿床进行多种方法的对比研究,来发现一种适合在红土覆盖区寻找隐伏矿的化探方法技术方案,用以覆盖区的推广。
[Abstract]:With the acceleration of modernization in China in recent years, the demand for mineral resources in the national economy and social development has maintained an upward trend.With the outcrop, semi-outcrop and shallow ore have become increasingly rare, overlying area prospecting has become the focus of geological exploration.However, the conventional geochemical prospecting method is not effective for deep-buried ore deposits. Therefore, more and more attention has been paid to the study of geogas and the dynamic extraction of soil.The work area of this paper is located in the Ta-Qian-Zhuxi-Fuchun copper polymetallic metallogenic belt in the red soil overlying area of Jiangxi Province. The deposits are all typical hidden deposits, which are still in the exploration stage, and there is no mining pollution.It is an ideal area to carry out geophysical survey, dynamic extraction test of soil and other geochemical exploration methods.Through the experimental study on the effectiveness of geogas survey in Zhuxi tungsten and copper mine and lunar copper mine, the experimental results show that the effect of different mining areas is quite different, and in Zhuxi mining area, due to the existence of a wide range of carbonate strata,It may restrict the migration of the components of the earth gas, the element content in the earth gas is relatively low, and the indicating effect on the concealed ore deposit is poor, while in the lunar mining area, there are clear and continuous anomalies above the hidden ore deposit, which is very good for indicating the concealed ore body.Be able to provide useful prospecting information.The dynamic extraction technology of soil was studied in Zhuxi tungsten and copper mining area. B- reagent was selected as extractant, and the experimental study was carried out with different concentrations and different extraction methods, and the results were compared with the total amount of conventional soil.From the experimental results, the active dynamic extraction method can obtain more information indicating hidden ore than conventional soil measurement. 0.2% concentration can provide more possibility than 0.5% concentration reagent.Dynamic extraction is more effective than static extraction in obtaining part of mineralization information from deep sources.This paper aims to find out a geochemical prospecting technique scheme suitable for searching for hidden ore deposits in laterite overburden area through the study of geochemical exploration methods in different mining areas and the comparative study of several methods for the same deposit.It is used to popularize the coverage area.
