Differential activity within Yishu fault zone and its caus es of formation;

Based on geological survey,the authors divided the seismogenic rocks in the Yishu fault zone and its periphery into four types,namely,seismite,seismic fault-tectonic rock,seismic volcanic rock and cryptoexplosive-seismic breccias.

In the Yishu fault zone and its surrounding area,seismites have been discovered in four horizons,i.

Characteristics of fluid inclusions from two types of gold deposits in central part of Yi-Shu fault belt and their geological significance;

Longquanzhan gold deposit in Yishui county locates in middle part of Yishu fault belt, which was controlled by Yishui-Tangtou fault.

The management information system for geothermal resources of Yishu fault belt was studied on the basis of Mapinfo software.

The faulting characteristics of Yishu fault are analyzed by using the levelling data.

Though the research geothermal geological condition,this article found out that the geothermal formation in Linyi segment of Yishu fault zone was relation with the fault,geological structure and magmatic activities.

Analysis on Connotation of Yishu Microlithic Culture;

The loading situation of Yishu Fault Zone in recent tectonic stress field is deduced from the focal mechanism solutions of minor shocks in the research area by using grid point cut and try method.
