摘要
湖北十堰—河南洛阳QB－1剖面大地电磁测深较好地反映了剖面通过的华北地台和秦岭地槽褶皱系的地电特征,圈出了壳内高导层和上地幔高导层,反映了两条切入上地幔深部的大断裂,推断嵩县大坪深部的低阻体可能为岩浆房,为研究深部地质构造提供了重要资料。
The telluric electromagnetic sounding performed along QB-1 profile from
Shiyan of Hubei province to Luoyang of Henan province reflects quite clearly
the geoelectric characteristics of North China platform and Qinling geosynclinal
folded belt that this profile passes through, delineates high-conductive layers
in the crust and in the upper mamtle, and reveals two great faults that cut
the deep part of the upper mantle; it is also inferred that the low-resistance
body at the depth of Daping (Songxian county) might be a magma chamber.
All these results serve as important data for the study of deep geology.
