【摘要】 通过四道沟金矿床找矿标志研究，及其对东西矿化带78，20号矿体地球化学探矿系统取样分析，分别确定了两矿体轴向分带序列．并经过对78，20号脉指示元素异常分析特点的综合统计分析，初步建立了金矿床的地球化学指示元素的轴向分带模式，从上、下是：Ti-CU-Sb-As-Bi-Ag-Au-Co-V-Pb，为确定预测盲矿体提供了较比可靠的地球化学勘查信息．并以此为依据，对20，78脉带深部找矿预测进行了较深入地讨论，结果表明，20号脉群深部找矿前景较大，78号脉群深部基于七中段显示出一定的有利成矿的地球化学找矿信息，同样存在盲矿体的可能性．更多还原

【Abstract】 On the basis of prognosis criteria research of Sidaogou gold deposit and sys-tematic geochemical sample analysis on vein No. 78 and No. 20 in the ease-west mineralizedzone, the axial zoning sequences of the chemical elements in the two orebodies are determinedrespectively, By comprehensive statistical analysis on the characteristics of the anomalies ofthe indicator elements in the two veins, the axial zoning pattern of the chemical elements inthe gold deposit is preliminarily established: Ti -Cu - Sb -As - Bi - Ag - Au - Co - V - Pbdownward from the top, which provides relatively reliable geochemical information for theprognosis of blind orebodies and on the basis of which ore prospecting in the depth of the twoveins is discussed in more detail. It is concluded that the deep part of No. 20 vein has greatpotential for ore prospecting. It is also possible to look for blind orebodies at the lower partof vein No. 78 as there is some favourable ore-forming geochemical evidence at Level 7 ofthe vein.更多还原
