| Abstract: | Using the secondary developing function of MapGIS,a lead isotope predication information system for blind deposits was established.The software kept up to date with the new theory of quantified predicating for ore body based on lead isotopic geochemistry.Taking advantage of the two-dimensional information data processing and three-dimensional modeling for the deposit district,the system realized the function of accurate and quick prediction for the embedding depth,geometric shape and resource quantity of the blind ore body.The Yingzuishan gold deposit is selected as an application example for the system,the basic mineral resources database is established and geological map,geochemical and geophysical anomaly map,exploration lines' profile for the deposit can be automated produced based on the database.Finally,based on the spatial analysis and integrated evaluation,three-dimensional model of the measured ore body for the Yingzuishan deposit was constructed and blind ore body of this deposit was predicated successfully. |
