| Abstract: | The authors made on-the-spot investigations in detail in Baoji-Pengxian, TianshuiBaolun areas; extensively collected the data of geology trenching and peeling-off soil;gathered rich years samples and pieces of tectonic rock;surveyed the sections of fluvialterrace. At the same time, the authors collected the data of remote-sensing pictureinterpretation and the results researched by predecessors in the research regions. Based onthe data, the authors made analysis of geology tectonic background, evaluation of faultactivity, seismogenic ability evaluation of the Holocene fault and evaluation of deformationand evaluation of seismic risk of the six major regions in the areas. The results of active faultinvestigation and the seismic risk analysis are furnished.The research areas are situated inthe place where Chuan,Shan, Gan three provinces meet. Previously seismic and geologyinvestigation and study were made very little in a systematic way in unity. To sorting outand publish the research results affords any one of the same trade or occupation fordiscussion and the parties concerned for reference. |
