A GIANTIC TECTONIC BELT RUNNING ACROSS EASTERN CHINA

Liu Xingsong  
On the basis of geomorphological, geological and geophysical studies as well as observations of seismic activities this report tries to show the existence of a giantic active deep-fault belt consisting of a system of horsts and grabens and stretching over eastern China.From the analysis of the structures, structural surfaces and elongation of this tectonic belt, as well as the studies of deposits, the tectonic belt under investigation may be considered as a result of the action of isostatic adjusment occurred after Yanshan movement, namely, a tracking fault belt of intense differential vertical movement predominated by tensional shear.As the belt exerts its control on sedimentary fades, draingage system and igneous activities-especially the existence of the ultrabasic rock belt, it may serve as an indicator of ore-searching and a reminder of the presence of a tectono-seismic belt as well.
