The Application Of Near-infrared Spectrum And Magnetic Susceptibility In Gold Deposit Forecast

In recent years, the near-infrared spectral analysis of minerals in many countries in the Europe and the United States were used in production; it can quickly identify the altered minerals and the combinations, and thus can improve the mineralization of the main information for mineral survey provided new evidence ;it has become one of the mineral survey the main instruments.Carring on the magnetic susceptibility to the rock to determine this research tool in the minerals reconnaissance profession application early is also relatively quite perfect.The study showed that:it has a very good effect using in the magnetic susceptibility to the rock strain and tectonism's research, the rock magnetic susceptibility means value and the anisotropy mineralizes the advantageous degree with the rock alteration degree and the gold have the very big relations. Moreover the magnetic susceptibility meter's application may reduce sampling, the system type and the chemical examination work load greatly reduces the chemical examination cost. The present paper is for the purpose of using the near-infrared spectral methods and the magnetic susceptibility analytic method two kind of open country prospecting side method unifies to the Inner Mongolian's Sunite right flag Bilihe mining area carries on the reconnaissance selection has the close origin contacting hydrothermal alteration belt with the gold ore, seeks looks for the target mining area, carries on the prospecting forecast. The concrete research technique is: 1) arranging the survey line in the choosen aera gathering sample (lothological sudden change place encryption);2) the use of the near-infrared spectroscope along the route, the magnetic susceptibility meter for gathering the sample to carry on the determination of analysis; 3) carring on the mining area known gold content's rock's near-infrared spectrum and the magnetic susceptibility characteristic and the golden personal status the contrast, summarizes the identification sign. With the mineralization forecast geological conditions, the survey results and access to major awareness are as follows:1)near-infrared spectral methods and the magnetic susceptibility method is quick, portable, sensitive, low-cost effective way to the scene quickly in the wild can be delineated and gold mineralization is closely related to the multi-element anomaly.Not only reduced the sample quantity which greatly must gather and analyze, moreover reduced geology sample's blindness, the site survey achievement and the geological research close union, the instruction prospecting predict that has the very good application prospect;2) near-infrared spectral method and the magnetic susceptibility law combination select the different type hydrothermal alteration in the volcano hydrothermal gold ore the application are feasible, and also for carried on the gold ore body's localization forecast in with all one's strength the Bilihe mining area and the periphery to provide the very meaningful material;3) taking the geological research as a foundation, unifies other transformation to search the method to carry on the contrast and the generalized analysis, may to prospect the forecast to supply more useful information.
