基于Surpac软件的归来庄金矿区矿化空间分析
|
摘要
归来庄金矿床位于中生代铜石杂岩体的东部边缘,是我国最大的隐爆角砾岩型金矿床,金矿主矿体受控于F1断层。为揭示主矿体深部矿化空间特征,指导深部找矿,利用Surpac软件建立了归来庄金矿主矿体三维地质模型。在对样品数据进行样长统计分析、处理特高品位等工作后建立块体模型,运用3次距离幂次反比法对金矿床资源量进行估算,并通过生成1-1号和1-2号矿体在不同方向和深度的品位变化趋势曲线,对三维模型金矿体估算结果进行验证与分析。通过建模实现了归来庄金矿体的三维可视化,通过分析建模结果,在深部发现了不整合面上还存在一层矿化体,为磨坊沟式金矿,可作为下一步深部找矿的方向。
Guilaizhuang gold deposit is located in the eastern margin of Mesozoic copper-stone complex.It is the largest cryptoexplosive breccia gold deposit in China,and also the largest gold deposit in Western Shandong Province. The mine has been exploited for 25 years since 1993 and has become a resource crisis mine. It is particularly necessary to carry out deep prospecting and peripheral prospecting. For a long time,a lot of scientific research work has been carried out in Guilaizhuang area,fruitful prospecting results and new understanding has achieved,and a lot of data was accumulated. Although the geological exploration degree in this area is very high,deep research is relatively weak.In order to reveal the three-dimensional characteristics of deep mineralization of main orebody and guide deep prospecting,a three-dimensional geological model of main orebody of Guilaizhuang gold mine was established by Surpac software.There are 13 gold orebodies delineated in Guilaizhuang gold deposit. Among them,No. 1-1 and No. 1-2 gold orebodies are the main orebodies. The orebodies mainly occur in the structural alteration zone of Guilaizhuang F1 fault and the surrounding rocks on both sides of the fault.The orebody is 450 m in scale,600 m in slope depth and 14 m in average thickness.Its occurrence is strictly controlled by alteration zone,which is consistent with the occurrence of F1 fault. Afterstatistical analysis of sample length and processing of super-high grade,a block model was established. The resource amount of gold deposit was estimated by 3 times of power inverse ratio method. The estimation,verification and analysis of the results of the three-dimensional model gold deposit were carried out by generating grade change trend curves of No. 1-1 and No. 1-2 orebodies in different directions and depths. The threedimensional visualization of Guilaizhuang gold orebody is realized through modeling,which is of great significance for guiding mine production design.In addition,by analyzing model results,a layer of mineralization body was found on the unconformity surface in the deep part,which provides a direction for further deep prospecting. The three-dimensional visualization geological model and location analysis results based on Surpac software have important reference value for Guilaizhuang gold deposit and its peripheral prospecting and exploration work.
