The Application Of High Accuracy Magnetic Survey In The Mineral Prospect Predicts

This article discussed the application of geology, geophysical, geochemistry, remote sensing ...etc. various methods in the mineral prospect predicts based on search and assay entirely both domestic and abroad and take the mineral prospect predicts project carried though in Tangfang-Shejule area as an example, and introduced the application of the method of high accuracy magnetic survey therein in detail.Comprehensive information mineral estimate prospect predicts with mineral-seeking model for foundation, use the information of geology, geophysical, geochemistry and geology remote sensing etc. to carry though the estimate work. It fixes attention on the geology conditional analysis that formed mineral and the research of mineral marking at the mineral bed and the summary of the mineralization rule. So it is less influenced by the issue of the reason that caused the mineral bed. As a result it has greater objectivity and function. Comprehensive information mineral predicts take the computer as tool, take various mathematics models as means, well develop each kind of mineral geology data contain the information about mineralization. It is advantageous to carrying out a mineral resources stereoscopic estimate, raise science of mineral estimate.The strategic mineral prospect predicts carried through in Tangfang-Shejule area takes lead, zinc, copper as the chiefly target. It found out the forming conditions of lead, zinc, and copper...etc. many metals minerals. It ascertains the area that is likely to mineralize and the abnormality result of geophysical and geochemistry. It makes use of a big scale ground geophysical, geochemistry, geology and remote sensing means match with earth's surface engineering to carry through the job of mineral prospect predicts ,then put forward the target areas can do further work and the lately discovered mineralization areas. The result of the geochemistry measuring, the remote sensing and the lately geology provide substantial evidence to the hermeneutic work of high accuracy magnetic survey data. Introduced the processing of high accuracy magnetic survey data to reach agreement to release in detail in the article, and give out the hermeneutic and initial conclusion of magnetic field abnormality based on the geochemistry, geology and remote sensing information.The inversion of magnetic anomaly is the important step which resolves an actual problem with geology explore. This article introduced how to do an inversion of magnetic anomaly by the mimesis NN method (optimization choice), and used this method to do simple inversion of magnetic anomaly in five certain sections.The method of comprehensive information mineral predict used in Tangfang-Shejule area indicate that the method is reasonable and applicable. Compared with the inquisition method of single geology or simple analogy, this method these advantages such as can get more information, more comprehensive, estimate marking credibility, more estimate according. It certainly will consumedly raise the quality of estimate work and make the objectivity of predict obviously increase. The research of comprehensive information can help us deeper to the understanding which controls a mineral rock body and controls mineral structure.
