Based on the techno-platform of Geographic Information System (GIS), by conversing from raster to vector of papery topographic map, this paper realizes the construction of digital elevation database of Minjiang Fault Zone (MFZ).

The longitudinal Minjiang fault is one of the most important faults on the eastern margin of the Qinghai-Tibet Plateau.

As a segment of the eastern boundary of the Qinghai-Xizang Plateau, the Minshan uplift is characterized by severe tectonism and seismism, bounded by the Minjiang fault on the west and Huya fault on the east.

According to the discussion of newly found north\|south trending active fault and ground fractures of Diexi earthquake,this paper inclined to consider that the north\|south trending active fault which might be the south extending of Minjiang fault is the most candidate for the g.

On the basis of an analysis of geological and geophysical data obtained by petroleum exploration in the South Poyang depression in recent years,the authors propose that the basining and tectonic evolution of the South Poyang depression were controlled by the activities of the Ganjiang fault zone under the constraint of the Yanshanian tectonic framework.

The Youjiang Fault zone is located in the Guixi (Western Guangxi) fault block region.

Analysis of the earthquake activity characteristics around the Nenjiang fracture belt;

The foliated dioritic rocks locating in Huangrhan - Wangpaze area, Zhuji County, the mid-dlepart of Jiangshao fracture belt,Zhejiang Province, have been studied in this peper.
