| 摘 要： | 通过时豫西嵩县中～新生代断陷盆地构造类型、断裂发育及其活动程度的初步分析，认为该盆地及其邻区具有断裂发育规模小、新构造活动程度低、盆内无次级断裂及其所围限的地堑和地垒断块构造发育等特征，从而形成了被深断裂割开的地震空区

PRELEMINARY DISCUSSION ON THE GEOLOGICAL ENVIRONMENT OF SEISMIC GAP IN SONGXIAN BASIN AND ITS PERIPHERY,WESTERN HENAN |
| |
| Abstract: | In this paper，the characteritics of Meso-Cenozcic Songxian faul basin in western Henan arestudied after a tentative analysis of tectonic pattern，fault development，and fault activity．It issuggested that there are some features in the basin and its periphery，such as small-scale faults，lower neotectonic movement，no graben，horst and fault-block movement confined by second-order faults in the basin.The seismic gap，therefore，is formed as the basin is cut by deep faultsalong the basin boundary |
