Method & Technique Study On Integration Explanation Of Region Information Of Geophysics And Geochemistry

This study worked over exploration and explaining method at integrating geophysics and geochemistry and looked back the past and forward to the future in the foundation of referring to a lot of information. The integrating explaining of geophysics and geochemistry will develop to four way: fix quantify and model and systematization and application of CIS.The most applied geography information system are ARC/INFO and PC ARC/INFO and Arc View made in ESRI company and Maplnfo made in Maplnfo company in USA and MapGIS and GeoStar made in China, they differ from characteristic and function and using method and used range. This study choosed Arc View GIS by way of foundation platform and developed the function modules for region geophysics and geochemistry (for example hydrological function and background analyst for region geochemistry and transformation for potency field and transformation of map projection and correlation analyst and grid data treating and inserter for Kriging and Trend and so on ) except using the basic functions of Arc View GIS(e.g. neighbour analyst and spatial data treating and surface analyst and model constructor and so on).The treating for every data is precondition and foundation of researching works at integrating information explaining. It is the geological data pretreatment to set off cells of geological body and to select model and forecast cells and to pick up and to evaluate geological variable, the evaluated geological cells are finally gridded by GIS. It is the geographical data pretreatment to unite the map projection and to workout map of catchment basin for analyst and explaining anomaly of sand and geochemistry. It is the region gravity and magnetism data pretreatment to transform the potency field data. It is the region geochemistry pretreatment to pretreat the originality data and to analyze the background and correlation filed and statistics data.Integrating information forecast for mine ought to follow the keystone of every subject and will be accomplished through integrating information explaining of geological and geophysical and geochemical data and picking-up and colligating some information concerned with mine and working out series maps of integrating information forecast for mine. The explaining for region gravity and magnetic data is accomplished by using result of potency field transformation through level and vertical relating with level one-difference of several height and vertical two-difference and working out construct map of region geophysics. The integrating explaining of region geochemistry data is accomplished by using some statistics method through researching geochemical element group in our area and picking up the geochemical anomaly.Mine forecast map of integrating information is accomplished by analyzing geological disciplinarian according to geological map and integrating explaining for geophysical and geochemical and sand and remote sense data and relating every integrating information to geological body and picking up information related with researched body. The basic matter ofmine forecast of integrating information is composed with the integrating sign of distributing disciplinarian of mine.Finding mine with integrating information is taking apart model ore field and bringing forward model to find mine and choosing measure of geology and geophysics and geochemistry and concluding the sign to find mine and forecasting resource on the basis of researching the relation of ore with older base and rock and stratum and construct.
