摘 要: | 五灵山—蒲包山地区在石炭纪时期,主要为潮坪—浅海泻湖沉积环境。依据岩石学、古生物学以及测井相综合分析,得出研究区主要发育有三种亚相,并可细分为七种微相,三种亚相为潮上带、潮间—潮下带和泻湖相;而潮上带又可分为泥(膏)云坪和潮池二个微相,潮间—潮下带分为颗粒滩和滩间泻湖二种微相,泻湖相又可分为泻湖浅滩和灰质泻湖两个微相。研究区随着海侵的继续,从蒸发潮坪到局限台地,再往开阔台地过渡。沉积相的研究为进一步勘探与开发提供了良好的科学依据。

Abstract: | In the Carboniferous period,the Pubaoshan -Wulingshan area is mainly the tidal flat - neritic continental depositional environment. Based on the comprehensive analysis of petrology, paleontology and electrofaeies, the stduy area can be divided into three kinds of the parfacies which also can be subdivided into seven microfaeies. The parfacies consist of supratidal zone, intertidal - subtidal zone and lagoon phase. The supratidal zone can be divided into two microfacies of mud or paste YunPing and tide pool ; the intertidal - subtidal zone is divided into two microfaeies of shoal and intershoal la- goon;and lagoon phase can be divided into two microfacies:grain shoal and lagoon. With the process of transgression,the research area has transited from evaporation tidal fiat to restricted platform, and then to the open platform. The study of sed- imentary facies provides a good scientific basis for the further exploration and development. |
