黔西南卡林型金矿聚集区作为滇黔桂"金三角"最重要的组成部分,其深部和外围找矿工作面临窘境。为突破传统化探找矿方法在深部矿产资源探寻中的难点,本研究选择泥堡金矿床外围区域进行1∶5万土壤地球化学和1∶5万构造地球化学弱信息提取对比研究。研究结果表明:构造地球化学方法能更有效地提取深部弱矿化信息,同时具有经济、实用且高效的特点。基于地质和构造地球化学特征,在研究区圈定4个综合异常,对成矿条件较好的Ⅱ号异常进行工程验证,取得了显著找矿成果。综合地质与化探研究成果认为,构造地球化学弱信息提取方法对泥堡金矿外围的找矿工作具有很好的指导作用,为研究区开展深部找矿工作提供了科学依据;经过进一步完善和推广应用,该方法可望在黔西南卡林型金矿找矿方面发挥重要作用。 |

The southwestern Guizhou gold ore concentration area is one of the most important parts of the Yunnan-Guizhou-Guangxi"golden triangle"in southwestern China,its deep and peripheral prospecting work is facing a dilemma.At present,traditional geochemical methods face great challenges in the exploration of deep hydrothermal minerals(such as carlin-type gold deposits in southwest Guizhou).In order to break through the difficulties of traditional geochemical prospecting methods in the exploration of deep mineral resources,the peripheral area of Nibao gold deposit was selected for a comparative study on the extraction of weak information of 1∶50 000 soil geochemistry and 1∶50 000 tectono-geochemistry.Through the comparative study of soil geochemical survey in the same region,it is found that the method of extracting weak information of tectono-geochemistry has the following characteristics:(1)The anomaly has good reproducibility,within the range of anomalies delineated by soil geochemistry,the extraction of weak information of tectono-geochemistry can also delineate anomalies.(2)The details are more obvious,and the anomaly area obtained by the extraction of tectono-geochemical weak information is larger in the area of soil geochemical anomalies,which can obviously magnify the"high,large and complete"anomalies and strengthen some anomalies.(3)The value of high value point increases exponentially,and the highest content of Au obtained from the weak information of tectono-geochemistry is tens of times higher than that of soil geochemistry,which can highlight the high anomaly.(4)The extraction of weak information is more effective and can form anomalies in the areas where the soil geochemical survey does not show anomalies,indicating that this method plays a good role in the extraction of weak mineralization information and the location and prediction of concealed deposits.(5)The number of tectono-geochemical weak information samples is only 60% of that of the same scale soil samples,the sampling intensity is significantly reduced,and the economy is prominent.In conclusion,the results show that the tectonogeochemistry is not only more effective to extract the weak mineralization information,but also has the characteristics of economy,practicality and efficient.According to the characteristics of geology and tectonogeochemistry,four comprehensive anomalies are delineated.Through the engineering verification of No.2 anomaly with better metallogenic conditions,the remarkable prospecting results have been obtained.Comprehensive results of geology and geochemistry in the study area show that the tectono-geochemistry weak information extraction provides a scientific basis for deep prospecting in the periphery of Nibao gold deposit.After further improvement and application,tectono-geochemical weak information extraction methods is expected to play an important role in prospecting for carlin-type gold deposits in southwestern Guizhou. |
