Application Research Of Integrated Geophysical And Geochemical Method In Siziwangqiwenduhua Area

SiZiWangQiWenDuHua region of aeromagnetic anomalies are discovered byaeromagnetic station of Inner Mongolia in2008, In order to verify the exception、enlargeprospecting prospect, this work also cooperate with the electrical method in geophysicalexploration, geochemical exploration, the main aim is to fully on the basis of existing datacollection, research, combined with the measured data obtained, based on the processing ofdata, to infer aeromagnetic anomalies of the ore body, so as to determine the temperaturedistribution of mineral resources in all.First, collect a lot of the research results on the metallogenic prediction at home andabroad and the related field application example of comprehensive geophysical method,analyzed the metallogenic prediction of geological and geophysical-geochemical model inthis workspace, analyzed on the distribution of all kinds of ore deposits from the regionalgeological background, then to determine the condition of the application of comprehensivegeophysical method, and establish the geological-geophysical-geochemical prospectingmodel; Second, proceed the ground high-precision magnetic survey in WenDuHua regions,selects the approximate scope and form of magnetic anomaly, combined with the basicknowledge of magnetic prospecting theory, made the magnetic survey data processing ofanalytical continuation and reduction to the pole; Finally, on the basis of combining withgeological mapping data, marking out smaller abnormal range, utilizing the means such aselectrical method, soil geochemical survey to complete the test zone of geophysical fielddata collection, combined with the formation, structure and physical property data andmodern metallogenic theory, inference and interpretation of results data after the dataprocessing work.On the basis of the fully study of geological and geophysical characteristics, there isan IP anomaly of this area to be inference and interpretation and drilling engineeringverification, The result is that cause the anomaly is graphite and three holes are all appearedmine, and determined the thickness of the ore body; Estimate the resources of this area.The practice proved: integrated geophysical-geochemical prospecting is a veryeffective method in this area.
