Gis Henan Bauxite-based Multi-source Information Integration And Management And Metallogenic Prediction

Along with the research of geoscience investigative and thorough,the data of geology increase fast.How to manage and analyze these gigantic data and extract the useful information from it,has been a new research direction of geoscience.Author makes research on geological feature of Henan aluminum deposits,and makes a summary of the law of the mineralization of aluminum deposits of Henan,so that provides a basis for minerogenetic prediction of Henan aluminum deposits.In order to integrate and manage the multi-information of the aluminum deposits in Henan, based on the research of integration and fusion of geological data, author codes the multi-geological data ,and buildes the spatial database and attribute database of multi-information about Henan aluminum deposits.And author uses MapInfo as the foundation of GIS, adopted visual programming language(Visual Basic ) and MapInfo'map component(MapX45), performs the GIS component development,establishes "Henan Aluminum Deposits Multi-information Integration and Management System",and achieved the aim to manage effectively complicated data of Henna aluminum deposits (geology, remote sensing, geophysic exploration and geochemical exploration data, etc).The system has certain changeability and practicability.Based on the laws of the mineralization of aluminum deposits of Henan, author uncoverd the relation between all of geological factors and mineralizetion with gis technique,and found out the advantage of mineralizetion.The method is speedy,intuitionistic and handy,that quicken the periods of research.Author carries out fractal analyse with fractal theory and gis software-Arcview33.The fractal results of research indicated that the distribution of aluminum deposits in Henan has the multifractal feature. The fractal dimension value has practical significance for perambulation of Henan' aluminum deposits.
