【摘要】 <正> 自1974年以来,我们开展了鲁西南、济阳坳陷、黄骅坳陷、冀中坳陷和燕山地区的构造研究;1976年曾提出鲁西旋扭构造体系,1977年更名为冀鲁帚状构造体系。通过近几年的工作,加深了对该体系的认识,进一步扩大了该体系展布的范围,研究了其形成时代、演化过程、动力来源,并对油气的控制作用进行了初步的探讨。更多还原

【Abstract】 Ji-Lu brush structure system, a gigantic rotational shear structure system lying in the North China subsidiary area of the second subsiding belt of the Neocathaysian system, consists of Western Shandong nuclear column and five large rock slices between vortical surfaces that occur in alternating arrangement of three depressions and two uplifts to the north of it. The spread type, genetic relation of the system is described. Formation and evolution of the structure system, also stres s mode at different stages are discussed. The Ji-Lu brush structure system has control over the formation and distribution of three large oilfields in China-North China, Dagang and Shengli, where favorable accumulation of oil and gas can be predicted based on tectonics study.更多还原
