Study On Spatial Data Model Of Tectonic Facies Map

With the advent of the information age, geographic information systems and network technology is increasingly being applied to the depth of geological areas. There is increasing attention to build up the data model of geological data which is the data from different sources and different connotations. In this paper, based on geological minerals information integration and mineralization forecast topic in Xinjiang and the Central Asia neighboring country, taking GIS as the data platform and unifying domestic and the overseas geological data model to construct the spatial data model of tectonic facies map. It can provide the effective data support for the metallogenic regularity and the mineral prediction.Tectonic facies map is foundation of metallogenic geological background research and cohere with the understanding of the geological theory researching and the geological processes. According to study the tectonic facies map of Balkhash- Junggar region, the article establishment geology conceptual model from two aspects which are tectonic setting and tectonic evolution. Based on the idea of information science, the article using Geodatabase data model and discussing feature class, attribute table and their mutual relations to construct tectonic facies spatial data model of Balkhash - Junggar region that based on the idea of information science. According to limited conditions, to deal with the basis of geological maps data through the method of adding attributes, information fusion, generalization, etc. By the simple spatial analysis, the basis of geological maps has been changed into the relevant maps. Finally, we can transform the tradition way that give priority to"draws"the map to the new way that through the basis of geological maps"produce"the map.The establishment of tectonic facies map spatial databases based on tectonic facies map data model, it can guarantee complete uniformity between spatial data's attribute and the visualization. Tectonic facies map can be a"live"map and it lively express multiple perspectives, multi-level, Thus realizes intellectualized expression of tectonic facies map.
