摘要/Abstract

摘要： 采用声波时差、裂变径迹以及地层对比等技术对济阳坳陷喜马拉雅运动Ⅱ幕的剥蚀厚度进行恢复,并对结果进行对比验证。结果表明,济阳坳陷从隆起到斜坡再到凹陷沉降中心部位,地层剥蚀厚度依次减小。南部的东营凹陷和惠民凹陷相对于北部的车镇、沾化凹陷具有较强烈的地层剥蚀。地层剥蚀厚度的横向差异反映了古近纪末期济阳坳陷内凸凹相间、西南高东北低的构造特征。

Abstract: The eroded strata recovery technologies such as sonic logging, fission track and strata correlation are used to recover the erosion thickness of the 2nd episode of Himalayan movement in Jiyang depression of Bohai Bay basin, and the result reveals that the denudation thickness becomes smaller from uplifts to slopes and to subsidence centers of sags. The erosion phenomena are more serious in DONGying sag and Huimin sag of southern Jiyang depression than in Chezhen sag and Zhanhua sag of northern Jiyang depression. The horizontal differences of denudation thickness suggest that the structural features at the Late Paleogene were characterized by the swellsag alternating and the high in the southwest and low in the northeast within Jiyang depression.

Key words: stratigraphic erosion, unconformity, strata correlation, Jiyang depression
