摘要
The authors obtained the crustal thickness and average crustal Vp/Vs ratio along the profiles across the Liaodong anteclise, Yanshan belt and Xingmeng orogenic belt using H-κ stacking of receiver functions. The result shows that the average crustal thicknesses of these three tectonic units are 32, 33 and 35 km, respectively, indicative of slight differences, and display distinct transverse variations in the crustal structure. The distinct crustal structures between the Yanshan belt and the Xingmeng orogenic belt are probably indicative of a more intense crustal modification in the Yanshan belt compared with the Xingmeng orogenic belt during Mesozoic-Cenozoic period.
