Abstract:Tectonic phase diagram database is an important part of mineral resource potentiality assessment. It is very important to survey and exploration of mineral resources. Establishment of tectonic phase diagram database can realize geological information management and data sharing of tectonic phase diagrams. In this paper, organizations of each map layer which have close relation in tectonic phase database and the establishment process of the whole spatial database have been described, and simple and effective method has been summarized as well.
