Based on the analyses of the core description,the petrology characteristic and section structure and taking Well HZ25-3-2 as a representative,the authors divide the sedimentary systems into two types,that is,the marine facies fluvial-dominated delta and continental shelf,discuss the essential features of the tow sedimentary systems,and then further recognize two.
以岩心描述、岩石学特征和剖面结构分析为依据,以HZ25-3-2井为代表,详细研究了珠江口盆地惠州凹陷新近系中新统珠江组砂岩储层的沉积相类型,从中划分出海相河控三角州和陆棚两种沉积体系,探讨了此两种沉积体系的基本特征,识别出连续进积型、连续退积型和加积型三角洲沉积演化序列和陆棚沉积演化序列。

通过对本区30多口井系统性沉积相研究认为,济阳坳陷晚古生代自下而上为海相、海陆过渡相和陆相沉积,划分了5种沉积体系:障壁-泻湖-潮坪体系、碳酸盐岩陆棚体系、三角洲体系、泥炭沼泽体系和河流体系。

After analyzing the data of drilling,logging and well logging,as well as facies marks,it is suggested that terrigenous clastic depositional system was developed in Early Cambrian(Qiongzhusi Stage and Canglangpu Stage)and mainly includes terrigenous clastic shore and shallow shelf facies;carbonate platform depositional system was developed in late Cambrian and is mainly composed of carb.
根据钻井、录井和测井等资料以及沉积相标志的综合分析,指出本区寒武纪早期(筇竹寺期和沧浪铺期)发育海相陆源碎屑沉积体系,主要包含陆源碎屑滨岸和浅海陆棚两种沉积相;晚期以发育碳酸盐岩台地沉积体系为特色,主要由碳酸盐潮坪、混积潮坪、半局限～局限海台地相组成。
补充资料：大陆
| 大陆 continent 地球表面高出海面，由陆壳组成的面积广大的陆地。地球上最大一级的地貌单元，约占地球表面面积的29％。地球上大陆有 6 块，按面积大小依次为亚欧大陆、非洲大陆、北美大陆、南美大陆、南极大陆和澳大利亚大陆。
