在总结杜荒岭矿区地质特征的基础上,通过对测区地电提取元素特征参数值进行统计并探讨,采用传统异常下限计算方法确定背景值划分异常带,圈定了该区Au,Ag,Cu,Pb,Zn,As,Sb,Hg,Bi9个元素异常范围。依据各地电提取元素异常平面空间分布特征,认为应注意深部和外围的闪长玢岩、次安山岩、石英闪长岩和花岗斑岩及其接触带,以寻找Au、Cu矿化体为目标。R型聚类和R型因子分析,表明研究区深部具有盲矿体或深部还存在第二个Au富集地段的可能性,Au的富集经历了热液温度由低—高—低的过程,Au的沉淀发生在热液温度由高—低的整个降温过程中,在一定程度上解释了成矿成晕过程。根据地电提取Au元素异常分布特征、规模强度及其所处的地质环境,圈定出5个异常区,并综合评价各异常区的成矿前景,为杜荒岭外围区进一步找矿工作提供可靠的地球化学依据。 On the basis of summarizing the geologic characteristics of Duhuangling mining area, the characteristic parameters of geoelectricity extracted from the survey area are calculated and discussed, and the anomalous zone of background value classification is determined by traditional lower limit of anomaly. The Au, Ag, Cu , Pb, Zn, As, Sb, Hg, Bi 9 element anomalies range. According to the spatial distribution characteristics of the anomalous plane elements extracted by different localities, it is considered that the diorite, sub-andesite, quartz diorite and granite porphyry and their contact zones in the deep and periphery should be paid attention to in search of Au and Cu mineralization . R-type cluster analysis and R-type factor analysis indicate that there is a possibility of a deep Au deposit in the study area or a second Au-enriched area in the study area. The enrichment of Au undergoes the processes of low-high-low hydrothermal temperature The Au deposition occurred during the entire cooling process when the hydrothermal temperature increased from high to low, to a certain extent, explained the process of mineralization and halo formation. According to the characteristics of anomalous distribution of Au element extracted by geoelectric power, the intensity of scale and the geological environment in which it is located, five anomalous zones are delineated and the mineralization prospects of each anomalous zone are evaluated comprehensively to provide reliable prospecting for further prospecting in the peripheral area of ​​Duquraling Geochemical basis.
