The Yishu fault system is the mainly active fault in the China East, which pression movement happened in the late Jurassic caused the invasion of the cala-alkaline magma and the relevant gold mineralization in the Jiaodong area.

Jiaolai Basin is a strike-slip and pull-apart basin controlled by the Yishu Fault Belt and Wulian -Jimo-Muping Fault.

They originated in a tectonic setting of strong activity of the Yishu fault.

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.
