Based upon invetigation of boring core in Zhenjiang, apical area in Yangtze delta, the Holocene transgression is dated between 9000 and 6300 years B.P., when sea level was located at 10—12m. and 2—3m. below the present Woosung level respectively. Since 6300 years in area of Zhenjiang boring deposited sediments of freshwater marsh, so it seems in Yangtze delta aea no sea level was higher than present one during 5000—6000 years B.P.

根据长江三角洲顶部镇江地区钻孔岩蕊的研究,全新世海水影响该地的时间为距今9000—6300年间,当时海面分別位于吴淞零点以下10—12米;2—3米。6300年以来镇江钻孔所在地区沉积淡水沼泽沉积,因此,5000—6000年前长江三角洲地区似无高于现今的海平面。

From four aspects, ie, the composition of the terrigenous clasts and the typomorphic features of the minerals, authigenic minerals, cements and matrix, the type of clastic rocks as well as the changes taken place after the burial of the sediments, this paper clarifies the basic features of the clastic rocks of the area. Some of their features indicate that the sediments were transitional in nature between the neritic sea and land, and were influenced by the action of saline water and fresh water dually and successively....

From four aspects, ie, the composition of the terrigenous clasts and the typomorphic features of the minerals, authigenic minerals, cements and matrix, the type of clastic rocks as well as the changes taken place after the burial of the sediments, this paper clarifies the basic features of the clastic rocks of the area. Some of their features indicate that the sediments were transitional in nature between the neritic sea and land, and were influenced by the action of saline water and fresh water dually and successively. The changes taken place after the burial of the sediments have some effects on their physical property. As to its source of material, it is of the feature of multi-origin, though it mainly owns its origin to the metamorphic rocks and granite mass in the southwestern margin of the basin.

本文对阜宁群碎屑岩类及古老母岩约500多个薄片进行分析鉴定,并从四个方面:即陆源碎屑成份和矿物标型特征;自生矿物、胶结物和杂基;碎屑岩类型;以及沉积物埋藏后的变化等特点,阐述了本区碎屑岩类的基本特征.研究结果表明,阜宁群沉积物是在淡水注入和海水侵进下,即两种水体交互作用下形成的.同时,针对本区沉积物埋藏后的变化,具体说明了对物性条件的影响.最后,对物源问题进行了分析,提出本区具多物源的特点,但突出的主物源区是来自盆地西南缘的广泛分布的变质岩系和花岗岩体。

The Permian System in Sichuan basin is composed of shallow water carbo- nate rocks deposited on a platform in a warm and humid climate with very flouri- shing biota.Dolomitization occurred under the following circumstances:(1)repl- cement by large coarse-grained dolomites along the fractures and pores;(2)repla- cement by small rhombohedral dolomites along the suture lines and(3)replacement by large coarse-grained dolomites of fresh-saline water origin.The last mentioned dolomites predominate the other two,with the ancient carbonate rock upland of biolith origin in neighboring provinces playing the controlling role.
