河南省地壳结构和深断裂简述

DISCUSSING ON CRUSTAL STRUCTURE AND DEEP FAULTS OF HENAN PROVINCE

利用重磁资料正反演计算，获得了一系列的地壳深部资料。多种资料综合反映了河南省深部构造的主要特征。本文论述了我省地壳层状结构的特点和深断裂带的划分。首次提出黄河南断裂带、驻马店－桐柏断裂带为超壳断裂带；确山－固始断裂带、南阳断裂带为地壳断裂带。

Using direct and inversed evolution calculation for gravity and magnetic data,a series of data in deep crust have been obtained.The multiple data reflected the major characteristics of deep fault of Henan Province,and the characters of layered structure in crust and division for zone of deep fault are discussed.The zones of the south of Huanghe River fault and Zhumadi-an-Tongbai fault are ultracrustal fault,zones of Queshan-Gushi fault and Nanyang fault are crustal fault.
