【摘要】：隨著近年來(lái)我國(guó)現(xiàn)代化進(jìn)程的加快,國(guó)民經(jīng)濟(jì)和社會(huì)發(fā)展對(duì)礦產(chǎn)資源需求量保持上升趨勢(shì)。并且隨著露頭礦、半露頭礦和淺層礦等已日見(jiàn)稀少,覆蓋區(qū)找礦已經(jīng)成為地質(zhì)勘查工作的重點(diǎn)。而常規(guī)化探方法對(duì)于埋藏較深的礦床找礦效果不好,因此,地氣測(cè)量研究以及土壤活動(dòng)態(tài)提取技術(shù)越來(lái)越受到重視。本文工作區(qū)位于紅壤覆蓋區(qū)的江西塔前-朱溪-賦春銅多金屬成礦帶,礦床都是典型的隱伏礦床,至今還處于勘查階段,尚無(wú)采礦污染,是展開(kāi)地氣測(cè)量和土壤活動(dòng)態(tài)提取試驗(yàn)及其他化探方法勘查試驗(yàn)較理想的地區(qū)。通過(guò)對(duì)朱溪鎢銅礦區(qū)和月形銅礦區(qū)展開(kāi)了地氣測(cè)量勘查有效性試驗(yàn)研究,有效性試驗(yàn)性結(jié)果表明,不同礦區(qū)效果差異比較大,在朱溪礦區(qū),由于大范圍碳酸鹽地層的存在,可能限制了地氣組分的遷移,地氣中元素含量都比較低,對(duì)隱伏礦床指示效果較差;而在月形礦區(qū),地氣異常在隱伏礦上方有著清晰、連續(xù)的異常,對(duì)隱伏礦體指示效果很好,能夠提供有用的找礦信息。在朱溪鎢銅礦區(qū)同時(shí)進(jìn)行了土壤活動(dòng)態(tài)提取技術(shù)的研究,本文選擇了B-試劑作為提取劑,進(jìn)行了不同濃度、不同提取方法實(shí)驗(yàn)研究,并與常規(guī)土壤全量進(jìn)行對(duì)比。從實(shí)驗(yàn)結(jié)果來(lái)看,活動(dòng)態(tài)提取方法能夠獲得比常規(guī)土壤測(cè)量更多指示隱伏礦的信息。0.2%濃度比0.5%濃度的試劑能夠提供了更多可能,動(dòng)態(tài)提取比靜態(tài)提取方法更能夠獲得部分來(lái)自深部礦化信息。本論文旨通過(guò)對(duì)不同礦區(qū)的勘查地球化學(xué)方法研究以及對(duì)同一個(gè)礦床進(jìn)行多種方法的對(duì)比研究,來(lái)發(fā)現(xiàn)一種適合在紅土覆蓋區(qū)尋找隱伏礦的化探方法技術(shù)方案,用以覆蓋區(qū)的推廣。
[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.
