摘要
上芒岗卡林型金矿床的强烈红土化作用 ,形成了上部红色粘土型金矿体 ,产生了一定范围的次生地球化学异常。金矿区红色粘土剖面可分为表土带、坡积带、钙华 沼泽带、残积带、腐泥带和基岩带。在原生卡林型金矿红土化作用过程中 ,黄铁矿、毒砂、辉锑矿、方铅矿、闪锌矿等硫化物矿物发生氧化作用 ,S、As、Sb、Pb等有害元素将被有效释放进入地下水和红色粘土中 ,进而造成地下水和土壤的污染。
The extensive red clayization of the Shangmanggang Carlin type gold deposit is responsible for the upper red clay type ore bodies and the widespread secondary geochemical anomalies. The red clay profile can be divided into six zones such as topsoil, slopewash, travertine fan, eluvial deposit, saprolite and bedrock. During the red clayization, harmful elements such as, As, S, Sb and Pb could be effectively released into the red clay and water to result in water and soil pollutions because of the oxidation of sulfide minerals such as pyrite, arsenopyrite, stibnite, galena, and sphalerite,.
