渤海湾盆地济阳坳陷凹隆结构类型及其对沉积的控制作用
Depression and apophysis structure type and its controls on deposition in the Jiyang Depression, Bohai Bay Basin
摘要
Abstract
Glutenite oil deposits in steep slope zone are major hydrocarbon exploration targets in rift basins. Drilling proves that near?source coarse debris sediments were well developed on the downthrown side of EW oriented faults. On the contrary, near?source sediments seldom or even did not develop on the downthrown side of N(N)E oriented faults. The article discussed the coupling relationship between bulge and depression, and came up with two kinds of coupling relationship which are the mountain?upheaval basin?sedimentary type and basin?sedimentary mountain?upheaval type, focusing on this special phenomenon and based on the recovery of the denudation quantity in the bulge area. Prove?nance area, erosion thickness and passageway development degree determined whether near?source sediments deposited or not based on the studies of the Dabie orogenic belt. The deposition characteristics of the downthrown side of the EW and N(N)E oriented faults were analyzed, indicating that the EW faults are syndepositional ones and the N(N)E faults are right?lateral strike-slip ones influenced by the SN extensive stress during Paleogene. The difference between kinematic properties and activity time is the main cause of sedimentation difference.关键词
