| 中文摘要: |
| 抚顺—清原地区是辽宁省最重要的铜矿产地，但近年来资源量急剧减少，开展铜矿资源进一步找矿工作已十分紧迫。文章依托"辽宁省铜矿资源潜力评价"和"辽宁省矿产地质志"项目所收集到的地、物、化、遥、自然重砂等资料，在建立红透山式铜矿找矿模型、提取证据因子的基础上，应用MRAS软件的证据权重模型模块对抚顺—清原地区红透山式铜矿进行矿产预测。共圈定找矿远景区10个，以计算得到的后验概率（P）将其划分为Ⅰ级找矿远景区4个、Ⅱ级找矿远景区3个、Ⅲ级找矿远景区3个；并利用找矿信息量预测等值线图和色块图对预测成果进行了表达。 |
| 英文摘要: |
| Fushun-Qingyuan area is the most important copper producer in Liaoning Province with resources sharply declined in recent years. It is urgent to prospect for more resources. In this paper prospecting model for the type of massive sulfide deposit is built on basis of the collected data of geology, geophysics and geochemistry, remote sensing, potential evaluation of copper resources and geological records of minerals in Liaoning, and natural heavy concentrate and evidence weight factors extracted. Then weight of evidence modules of MRAS is used to predict such ore in the Fushun-Qingyuan area.10 targets are delineated of which 4 targets Ⅰ, 3 targets Ⅱ and 3 targets Ⅲ are divided by the calculated inspection probability (P) and the prediction result is also shown by contour map and color chart of the prospecting information volume prediction. |
