Abstract:
We present a geologic map of the Tekeze River basin that covers an area of ∼69,000 km2 of northern Ethiopia. The map synthesizes new data collected in two campaigns between March, 2012 and January, 2013 and compiled at a scale of 1:500,000 with published geologic surveys. The map focuses on the main geologic and tectonic features relevant to a modern interpretation of the geologic evolution of northern Ethiopia and as such, it represents an important synthesis for environmental and natural resource management.Keywords:

The studying object of this paper is the geologic map data of the Balkhash-Junggar. In this paper,the geologic map database model of Balkhash-Junggar is constructed combining with tectonic background based on spatial database. Then a new mapping method is created by the proceeding of building a tectonic facies map according to the geological map. The result of the experiment testify that this method make up the limitation of the traditional digital map-making,and also enhance the effectiveness and practicality of tectonic facies map.
