Application And Effection Of Soil Geochemical Survey In Baogedewula Inner Mongolia

It is difficult to predict and evaluate mineral in the semi-arid grassland coverage area.Even this is one of the studying hotspots in the recent years.The tudying area located in thenortheast of Inner Mongolia, where covered with extensive Quaternary. Grass grows well,but the revers do not develop well. The aeolian sands is very common above the surface.All the factors contribute the difficulty of looking for hidden surface mine-half buriedpolymetallic deposit.Soil geochemical survey is a conventional and classic method by collecting loosescrap, analyzing the contents or other element geochemical characteristics found in soilgeochemical anomalies. we can achieve to explore by this way.By colleting the relevant researched dates of others. The outher summarized thenatural landscape features, soil geochemical survey and metallogenic potential anomaliesdelineated area delineation and post geochemical abnormal verification of the studying area.And got five conclusions:①The studying area belongs to the arid and semi-arid grasslands including remnantablation-the hills-the leveling of the plateau grasslands alternating, each with an area ratioof about25-30%,25-30%,40-50%.②Clastic collected from the C layer or the BClayer is better whose are usally0.5meter deep, diameter is between80and100mesh. But we must get the clastic through theleaching layer (A layer) and deposited layers (B layer) and regional development calichepossible.③49geochemical abnormal werefounded by1:50000soil geochemical survey.andseven of them were verified by the late works to polymetallic deposits (mines).④study area in eastern sand Shanagen-the treasure Gede Urals conducted soilgeochemical exploration1:10000get abnormal area, concentration centers obvious W-Moanomalies, drilling verified through post for the medium W-Mo deposit, in the early1:50000based on refinement, while a clear anomaly, verify the feasibility of exploration inthe soil of the study area.⑤two sets of measurements of abnormal elements and good, large abnormal area,extreme high and abnormal central prominent geochemical anomaly is a direct geochemicalprospecting way.
