In order to quickly and easily study on information of the deep crust and the upper mantle lithosphere using MT data, based on the Microsoft SQL Sever database of MT results that is established for the first time and combined with Visual Basic language and secondary development of MapGIS components, query functions of MT results including spatial data and attribute data are achieved in this paper. Convenient support for lithospherie electrical structure in different research is provided. Meanwhile, to the middle and lower reaches of the Yangtze river metallogenic belt for example, a preliminary study of the electrical structure of the lithosphere is carried out by the data query capabilities of MT results, and this applica- tion have achieved a certain effect.
