| 中文摘要: |
| 通过WorldView-2高分辨率影像的遥感解译和Aster影像的遥感蚀变信息提取,在新疆迪木那里克铁矿带东段河肃地区开展火山沉积变质型铁矿遥感找矿预测工作。在分析区域典型铁矿床成矿地质特征及成矿规律的基础上,以河肃铁矿为例,充分利用WorldView-2高分辨率遥感影像的优势,总结了成控矿要素影像特征,提取了遥感蚀变异常,建立了区域火山沉积变质型铁矿的遥感找矿模型。在此基础上,对长沙沟成矿有利地区进行了深入研究,圈定了3处找矿靶区,经验证找矿效果良好。应用遥感信息进行找矿预测,对在该区找寻火山沉积变质型铁矿有一定指导意义。 |
| 英文摘要: |
| Based on remote sensing interpretation from WorldView-2 high-resolution satellite image and extracted alteration information from Aster satellite image, the prospecting prediction for the volcano-sedimentary-metamorphic type iron deposit in the Hesu area, eastern Dimnalic iron metallogenic belt, Xinjiang, was carried out. On the basis of analyzing regional metallogenic geological characteristics and metallogenic regularity of iron deposits, the image features of WorldView-2 high-resolution satellite data related to mineralization was summarized in the case study of Hesu iron deposit area, and the alteration information related to mineralization was extracted. And the RS prospecting model for regional volcano-sedimentary metamorphic type iron deposit was constructed. Based on the prospecting model, three prospective areas have been outlined in Changshagou area in combination with geological and geophysical information, and the engineering verification indicated there is satisfactory prospecting results. The study result shows that the remote sensing information has played a good role in guiding the exploration of regional volcano-sedimentary metamorphic type iron deposits. |
