华北地区寒武系第三统鲕粒滩的展布特征及其控制因素
|
摘要
华北板块内寒武系第三统普遍发育鲕粒灰岩,其展布特征和迁移规律值得进一步研究。在大量野外地质考察的基础上,结合地震、钻井等资料的解释以及前人对中国北方古地理的研究,根据其沉积特征并结合"优势相+特殊相"编图研究方法,认为华北板块内部围绕着鄂尔多斯古陆核,向华北板块周缘延伸,依次发育潮坪相、局限台地相以及开阔台地相等3种沉积单元,鲕粒在华北台地上大范围出现主要受到古地貌、水下隆起和海平面变化等外部条件的制约,而沉积相带的展布则控制着鲕粒滩的分布范围以及迁移的方向。高能的鲕粒滩主要分布于开阔台地相中,其次为潮坪相;而局限台地相内发育的多为反映低能环境的放射状鲕粒。高能鲕粒滩受到沉积相带控制,大多分布于开阔台地中靠近局限台地的一侧和潮坪边缘地区,并随着相区沿海侵的方向往内陆推进而不断迁移。
Oolitic limestones were developed widely in the Third Series of Cambrian in North China,and its' distributing characteristics and migration laws were further researched and summarized.On the basis of a large number of field geological investigations,in combination with seismic and drilling data and the predecessors' research of paleogeography in North China,as well as the "advantage facies + special facies" plotting methods,it was considered that there were 3 sedimentary facies developed from Ordos old land to the margin of North China plate,including tidal flat facies,open platform facies and restricted platform.The Oolitic limestone development depended on external conditions such as palaeogeomorphology,underwater upwarping and sea-level changes.The distribution and migration direction of oolitic shoal were controlled by sedimentary facies distribution.High-energy oolitic shoal was mainly distributed in the open platform,the restricted platform was the next.Within the restricted platform facies,Oolitic limestones are mainly composed of radial ooides reflecting the low-energy environment.By sedimentary facies controlling,A majority of high-energy oolitic shoals are distributed in the side of open platform near the restricted platform and tidal flat edge regions.and continuously migrated to the inland along with the direction of transgression.
