摘要

通过岩心观察描述，综合测井、录井、古生物、重矿物等资料，结合地震相分析，以瓯江凹陷构造演化及相对海平面变化为主线，从物源分析出发，综合分析瓯江凹陷明月峰组沉积相类型及沉积特征。晚古新世明月峰组沉积期，瓯江凹陷处于断拗转换阶段，沉积物源由凹陷西侧的闽浙隆起带酸性火山岩源区和凹陷东侧的雁荡低凸起提供，以闽浙隆起带物源占绝对优势，受中古新世至晚古新世中期大规模海侵的影响，相对海平面持续升高，凹陷东侧雁荡低凸起开始接受沉积，使得凹陷沉积范围达到断陷期最大，总体呈滨海—浅海沉积，闽浙隆起带物源供应充分，在凹陷西缓坡发育3个大型三角洲沉积，滨海沉积发育于凹陷西缘三角洲之间及雁荡低凸起位置，凹陷中央发育大范围的浅海沉积。控制明月峰组各沉积相空间展布的主控因素是构造和相对海平面变化，以相对海平面变化为主。

Abstract

By means of cores description,well log,logging,paleontology,heavy minerals,and seismic facies,we elucidate the material source of Mingyuefeng Formation in the Oujiang sag,and then comprehensively discuss sedimentary facies and its features,based on structural evolution and relative sea level change.At late Paleocene Mingyuefeng Phase,the Oujiang sag experienced the fault switching sag,the source sediments were transported from two sides of sag,the main source was Mingzhe structural belt in the western sag,and the second was Yandang low bump in the eastern.When the large-scale transgression at middle and later Palaeocene caused the relative sea level rising,the Yandang low bump started accept the sediments and reached the biggest sedimentary area.The sedimentary facies of the sag are representative of seashore and shallow sea,with the abundance of sediment supply from the Mingzhe structural belt.Three large\|scale delta sediments were formed at the western slope of sag,where the seashore sediment lie at the margin of sag,and th-shallow sea sediment was located in the centre of sag.The distribution of sedimentary facies is mainly controlled by structure and the of relative sea level change,especially the later.
