| 摘 要： | 以洛伊地区石油地震、钻井及地化资料为基础，利用镜质体反射率（Ro）进行单井剥蚀厚度恢复，应用平衡剖面恢复的早-中侏罗世古地貌呈"三凹三凸"特征，其中，中条山、熊耳山、嵩山由于隆升无早-中侏罗世沉积，在洛阳-济源、义马-宜阳、伊川形成3个沉降中心。依据盆地充填序列及沉积相带进行分析，认为研究区早-中侏罗世为山间坳陷盆地，其形成与演化受控于印支末期-燕山早期的秦岭-大别造山带陆内造山作用。

| Abstract: | Based on the oil seismic, drilling and geochemical data of Luoyi area, the author, using the technique of Ro for single well denudation thickness restoration and the balanced profile restoration, presents a characteristics of "three concaves and three convexes" of the ancient landform in early-middle Jurassic. As the uplifts of the Zhongtiao mountain, Xionger mountain and Songshan mountain caused the absence of the sedimentation of the early-middle Jurassic, thus formed the three concaves of Luoyang-Jiyuan, Yima-Yiyang, Yichuan. According to the analysis of the basin-fill sequence and the sedimentary facies, the early-middle Jurassic research area is the intermontane depression basin, whose formation and evolution is controlled by the intracontinental orogeny of the Qinling-Dabie orogenic belts in late Indosinian-early Yanshan. |
