【摘要】：為了在云南西邑鉛鋅礦區(qū)外圍和深部尋找隱伏鉛鋅礦,在董家寨礦段開(kāi)展了地電化學(xué)法找礦研究,對(duì)鉛鋅礦石進(jìn)行了電化學(xué)溶解并在已知礦體上開(kāi)展了地電化學(xué)法找礦可行性試驗(yàn)。結(jié)果表明:外加電場(chǎng)作用不僅會(huì)使鉛鋅礦發(fā)生電化學(xué)溶解,同時(shí)地電化學(xué)法也可將溶解出來(lái)的Pb、Zn等成礦離子提取;已知礦體上方同步出現(xiàn)了Pb、Zn、Ge、Ag異常,地電提取的異常值大小為PbZnGeAg,為典型的噴流熱水沉積富鍺銀鉛鋅礦的地球化學(xué)標(biāo)志;在此基礎(chǔ)上,利用地電化學(xué)法在西邑董家寨未知區(qū)開(kāi)展了找礦預(yù)測(cè),共圈定了5個(gè)綜合異常區(qū),其中Ⅰ類異常區(qū)2個(gè)、Ⅱ類異常區(qū)2個(gè)、Ⅲ類異常區(qū)1個(gè),為下一步勘查找礦工作奠定了基礎(chǔ)。
[Abstract]:In order to find concealed lead-zinc deposits in the periphery and deep of Xiyi lead-zinc mine in Yunnan Province, geoelectrochemical prospecting was carried out in the Dongjiazhai section. The electrochemical dissolution of lead and zinc ore was carried out and the feasibility test of geoelectrochemical prospecting was carried out on known ore bodies. The results show that the applied electric field can not only cause the electrochemical dissolution of lead-zinc ore, but also extract the dissolved Pb,Zn and other ore-forming ions by geoelectrochemical method. The anomalous value of geo-electric extraction is PbZnGeAg, which is a typical geochemical marker of germanium rich silver-lead-zinc deposit deposited by hot water, on the basis of which, the geoelectrochemical method is used to carry out the prospecting prediction in the unknown area of Dongjiazhai, Xiyi. A total of 5 synthetic anomaly areas have been delineated, of which 2 are type 鈪，
