| 中文摘要:哀牢山北段金矿田地面波谱反射率与ＴＭ图像亮度存有显著的线性相关关系。基于这种线性相关性，笔者用矿田内典型金矿床地面波谱的野外实测数据，经ＴＭ的相关分析，在哀牢山北段建立了９个地空相关模型。据这些相关模型，将ＴＭ图像反演成与金矿地面波谱有关的地空相关图像后，文章对该图像应用效果进行了讨论，认为其有较好的找矿靶区优选与定位的效果。 |

| Abstract:Based on the ground spectrum study of gold deposits in northern Ailaoshan located in the western part of Yunnan Province, authors have used the TM correlation analysis and established nine ground space correlation models from the image processing area On the basis of the nine ground space models and with an image computer system, the TM image of the image processing area has been transformed into ground space correlation image, which is related to the ground spectrum reflectivity of gold deposits in northern Ailaoshan This paper deals with the application effects of the ground space correlation image for the prognosis of gold deposits in the northern Ailaoshan area After the analysis of the ground space correlation image, authors have distinquished and detected some image anomalies from the correlation image In the field check of an image anomaly an auriferous quartz vein has been discovered by the authors The paper presents that the TM correlation analysis has the special ascendace for the prospecting and prognosis of gold deposits. |
