研究表明，华北地区南部是一个与秦岭-大别造山带密切相关的中新生代盆地。华北盆地南部的构造阶段包括：变质结晶基底（Ar-Pt_1）、裂谷盆地（Ch）、克拉通-裂谷盆地（Jx-Qb）、克拉通被动大陆边缘盆地（Z-O_2）的形成；隆起-弧后盆地（O_3-D_2）、克拉通-弧后前陆盆地（D_3-T_1）、印震旦系运动（T_2-T_3）、均质前陆盆地（T_3-J_2）、挤压冲断-拉分盆地（J_3-K~1_1）；逆冲隆升剥蚀（K~2_1 ~ k_2），裂谷盆地(E)和坳陷盆地（N-Q）。二叠—石炭系煤系地层是华北盆地南部主要的烃源岩。二叠系—石炭系煤系地层经过沉积、埋藏、隆升、剥蚀、再埋藏，油气可再生，煤系地层因此成为华北盆地南部油气勘探的主要目标。
Our study indicates that the south part of the North China Area is a Meso-Cenozoic basin intimately related with the Qinling-Dabie orogenic belt. The tectonic stages for the south of the North China Basin include: formation of the metamorphic crystalline basement (Ar-Pt_1), aulacogen-rift basin (Ch), craton-rift basin (Jx-Qb), craton-passive continental margin basin (Z-O_2); uplift and back-arc basin (O_3-D_2), craton and (back-arc) foreland basin (D_3-T_1), Indo-Sinian movement (T_2-T_3), homogenous foreland basin (T_3-J_2), compressional thrust and pull-apart basin (J_3-K~1_1); thrust, uplift and denudation (K~2_1-K_2), rift basin (E) and depression basin (N-Q). Coal measure strata of Permo-Carboniferous are the major hydrocarbon source rocks in the south of the North China Basin. After deposition, burial, uplift, denudation and re-burial, hydrocarbon can be regenerated in the re-buried coal measure strata of Permo-Carboniferous, and the coal measure strata hence became the major targets for oil and gas exploration in the south of the North China Basin.
