| Abstract: | RS technology is used to extract ore-finding information like linear structure,ring structure and mineralized alteration.Quantitative analysis is made on linear structure iso-density,central symmetry,advantageous degree,hydroxyl and iron staining information based on probability and mathematical statistics.Together with the existing geological material,synthetical analysis and metallogenic prediction are made and 7 ore-finding forecast zones are confirmed,which will give instruction to seek deposit in the future. |
| Keywords: | remote sensing abnormal structural information ore-finding forecast mountains in northern Tianjin |
