| 中文摘要: |
| 在山东省五莲七宝山地区矿产资源潜力评价中,选择七宝山铅锌矿为典型矿床,确定了模型区,通过大比例尺地物化遥等综合信息圈定最小预测区。采用含矿地质体体积法(核心算法:预测资源量＝最小预测区面积×延深×含矿地质体面积参数×相似系数×模型区含矿系数),全区共预测1000 m以浅铅锌资源量112.69万t。引用典型矿床深部及外围预测资源量作为模型区的资源总量,进一步提高模型区含矿系数的精度,使预测结果更加合理可靠。 |
| 英文摘要: |
| In the evaluation of mineral resources potential in Qibaoshan area, Qibaoshan lead-zinc deposit is selected as typical deposit , the model areas are defined. The minimum prediction area is defined by comprehensive metallogenic information, includes:large scale geology, geochemistry, geophysical and remote equalization. The Ore-bearing geologic body volume method is used to improve the reliability of mineral prediction results. The algorithm is :the calculated mineral resources = minimum appraisal area × dip extension × area parameters of the ore-bearing geological body × similarity coefficient × ore-bearing coefficient of the model area. A total of 1,126,900 t of lead and zinc resources above 1000 m were predicted. The predicted resources in the depth and periphery of typical deposits are taken as the total resources in the model area to further improve the accuracy of the ore-bearing coefficient in the model area and make the predicted results more reasonable and reliable. |
