九龙江口、厦门西海域磷的生物地球化学研究──Ⅲ.生物活动参与下的磷形态转化及磷循环估算

１９８７年３月～１９８８年１２月笔者于九龙江口、厦门西海域的调查研究结果表明，厦门西海域特殊的地理、水文环境、沉积物的高磷量、磷形态的快速转化是西海域初级生产力［５５５ｇ／（ｍ＾２·ａ）］比九龙江口区［１５９ｇ／（ｍ＾２·ａ）］高得多的主要原因。颗粒态磷（ＰＰ）、溶解态无机磷（ＤＩＰ）、溶解态有机磷（ＤＯＰ）等以生物为媒介发生了某种程度的形态转化，本文估算了九龙江水总磷（ＴＰ）的入海通量为７８７ｔ

韩国西南白垩系最下部Kyokpori组的漂砾沉积物研究

韩国西南白垩系最下部Ｋｙｏｋｐｏｒｉ组的漂砾沉积物研究＊Ｓ，Ｂ．Ｋｉｍ等１．引言（扇）三角洲陡坡上粗粒沉积物的水下沉积过程由各种非粘性沉积运动所共同控制，包括无粘性碎屑流、碎屑崩坍和高密集度的浊流（评论，见Ｎｅｍｅｃ，１９９０）。这些推论在很大程度上...     

南沙群岛海域构造地层及构造运动

根据对“实验２”号调查船１９８７－１９９１年测得的反射地震剖面的解释，论述了南沙群岛海域的构造层划分、时代属性与分布特征。提出本区自白恶纪中期以来发生过两次重大的构造运动，形成两个裂谷作用构造旋回。     

珠江河口铜、铅、锌、铬和镉对单细胞藻类生长的影响

通过现场采水样和实验室模拟,研究珠江河口环境在一连串变化过程中,当各种浓度的Cu,zn,Pb,Cr和Cd单独存在或共存时,对单细胞藻类——硅藻和扁藻的毒性影响。     

晋江河口及泉州湾湿地生物分布特点

泉州湾受晋江河口径流影响很大，导致湿地生物的水平分布与盐度的分布紧密相关．大致分为湾外和外湾种、内湾低盐种、感潮河段咸淡水种．长腕和尚蟹、扁平蛛网海胆和文昌鱼仅分布在外湾或湾外的砂质海底．3种红树植物、互花米草、招潮蟹、弹涂鱼是内湾泥滩的优势种．咸水草是感潮河段咸淡水指标种．河蚬虽是淡水种，也分布在低盐河段．     

Hydrocarbon Potential of Pre-cenozoic Strata in the North Yellow Sea Basin

The North Yellow Sea Basin ( NYSB ), which was developed on the basement of North China (Huabei) continental block, is a typical continental Mesozoic Cenozoic sedimentary basin in the sea area. Its Mesozoic basin is a residual basin, below which there is probably a larger Paleozoic sedimentary basin. The North Yellow Sea Basin comprises four sags and three uplifts. Of them, the eastern sag is a Mesozoic Cenozoic sedimentary sag in NYSB and has the biggest sediment thickness; the current Korean drilling wells are concentrated in the eastern sag. This sag is comparatively rich in oil and gas resources and thus has a relatively good petroleum prospect in the sea. The central sag has also accommodated thick Mesozoic-Cenozoic sediments. The latest research results show that there are three series of hydrocarbon source rocks in the North Yellow Sea Basin, namely, black shales of the Paleogene, Jurassic and Cretaceous. The principal hydrocarbon source rocks in NYSB are the Mesozoic black shale. According to the drilling data of Korea, the black shales of the Paleogene, Jurassic and Cretaceous have all come up to the standards of good and mature source rocks. The NYSB owns an intact system of oil generation, reservoir and capping rocks that can help hydrocarbon to form in the basin and thus it has the great potential of oil and gas. The vertical distribution of the hydrocarbon resources is mainly considered to be in the Cretaceous and then in the Jurassic.     

东营市东辛2-4井磁性地层划分对比研究

本文通过东辛2—4井岩心样品的古地磁学研究,整段岩心呈现以正极性为主的混合极性特征。自上而下划分的布容、松山、高斯和吉尔伯特极性时和布容极性时内清晰显示出的哥德堡和布莱克亚时的界限分别位于井深28.0m、161.0m、274.5m和452.0m。据黄河口南北5个钻孔磁性地层的划分对比,长江口、苏北盆地和东营地区,吉尔伯特、高斯和布容极性时的沉积速度较快,松山极性时较慢或近于缺失;黄河口以北至河北地区,高斯极性时地层不发育,吉尔伯特、松山和布容极性时则较厚,表明它们所处的构造单元、地质基础和沉积环境有较大的不同。
