1南海东北部海底沉积物波的形态、粒度特征及物源、成因分析显示文摘在南海东北部广泛发育沉积物波。通过高分辨率多波束数据、地震剖面以及重力柱状样,对沉积物波的形态特征、粒度特征、物源以及形成机制进行了分析。研究表明大致以台湾浅滩南海底峡谷为界,北侧为近北东向展布,南侧为近南北向展布。对其分布规律、地貌和形态特征及重力柱状样粒度分析表明这些沉积物波为浊流成因。沉积物波的发育与新生代晚期研究区的构造活动密切相关,自距今6.5 Ma以来台湾造山运动使台湾岛强烈抬升剥蚀,这些剥蚀物为研究区提供了大量的陆源物质,而在南海东北部陆坡区大量发育的峡谷-冲沟系统为陆缘物质向下陆坡的输送提供了良好的通道。研究区西侧的东沙隆起长期处于抬升剥蚀状态,这种抬升剥蚀也为研究区沉积物波的发育提供了部分物源。随着坡度的减缓,浊流沉积物开始堆积,在台湾浅滩南海底峡谷的北侧形成了展布方向与冲沟垂直的沉积物波,而在南侧由于台湾浅滩南海底峡谷发生转向,浊流从水道中漫溢出来,沉积物堆积下来,形成了与原先水道近于垂直的近南北向的沉积物波。丁巍伟 李家彪 韩喜球 黎明碧 ERWIN Suess 2010海洋学报2010,32,2:23
2南海北部陆坡九龙甲烷礁冷泉碳酸盐岩沉积岩石学特征显示文摘本文对南海北部陆坡九龙甲烷礁采集的两个冷泉碳酸盐岩样品TVG-1和TVG-11进行了矿物学、岩石学和碳氧同位素分析研究。X-射线衍射分析(XRD)结果表明,自生矿物主要为文石、白云石和高镁方解石等,碎屑矿物含量较少。TVG-11中存在大量的文石,而TVG-1只保留了已转化为方解石的文石假象,据此可以推断TVG-1的形成要早于TVG-11。扫描电镜(SEM)显微结构特征显示,自生矿物主要是通过细菌的厌氧氧化作用,直接从冷泉中沉淀出来的。碳、氧同位素测试结果显示,碳酸盐岩具有强13C亏损和一定程度的18O富集的特征,TVG-1和TVG-11的δ13C值分别为-46.22‰和-52.88‰,均低于-40‰,表明碳源于微生物作用的甲烷厌氧氧化,是指示该海域存在冷泉的重要证据;TVG-1和TVG-11的δ18O值分别为3.19‰和4.07‰,存在一定程度的18O富集。碳氧同位素和矿物的显微结构特征都说明九龙甲烷礁碳酸盐岩是烃类渗漏微生物作用而形成的自生碳酸盐岩,可能是天然气水合物分解引起的沉积,显示该区存在水合物的可能性很大。邬黛黛 吴能友 叶瑛 韩喜球 黄永样 SUESS E 2009热带海洋学报2009,28,3:19
3南海东沙东北部甲烷缺氧氧化作用的生物标志化合物及其碳同位素组成显示文摘南海东沙东北部碳酸盐岩和泥质沉积物中的生物标志化合物组合及其碳同位素组成分析表明,研究区内甲烷缺氧氧化作用(anaerobic oxidation of methane-AOM)发育。研究区内碳酸盐岩中含丰富的AOM标志化合物,2,6,11,15-四甲基十六烷(Crocetane-Cr.)、2,6,10,15,19-五甲基番茄烷(Pentamethylicosane-PMI)和2,6,10,15,19,23-六甲基二十四烷(Squalane-Sq角鲨烷)的13C亏损强烈(δ13C值介于-74.2‰^-119.0‰PDB之间),表明碳酸盐岩形成于AOM,同时反映该研究区曾发生过强烈、持续的富CH4流体释放活动。柱状泥质沉积物中,AOM生物标志化合物在硫酸岩-甲烷过渡带(SMI—Sulfate-Methane Interface)边界附近相对丰度高,SMI之上样品中含量低,或未检出,表明现代环境在SMI附近有大量嗜甲烷微生物生长,使得深部上升的甲烷被大量消耗,很少有甲烷逸出海底。AOM生物标志化合物可用来指示SMI边界。不同站位、不同岩性AOM生物标志化合物组成(包括碳同位素组成)的差异反映了嗜甲烷古细菌组成的不同。于晓果 韩喜球 李宏亮 金肖兵 龚建明 Erwin SUESS 黄永样 吴能友 苏新 2008海洋学报2008,30,3:18
4Authigenic gypsum found in gas hydrate-associated sediments from Hydrate Ridge, the eastern North Pacific显示文摘Characteristic gypsum micro-sphere and granular mass were discovered by bin-ocular microscope in the gas hydrate-associated sediments at cores SO143-221 and SO143/TVG40-2A respectively on Hydrate Ridge of Cascadia margin, the eastern North Pacific. XRD patterns and EPA analyses show both micro-sphere and granular mass of the crystals have the typical peaks and the typical main chemical compositions of gypsum, although their weight percents are slightly less than the others in the non-gas hydrate-associated marine regions. SEM pictures show that the gypsum crystals have clear crystal boundaries, planes, edges and cleav-ages of gypsum in form either of single crystal or of twin crystals. In view of the fact that there are meanwhile gas hydrate-associated authigenic carbonates and SO42--rich pore water in the same sediment cores, it could be inferred reasonably that the gypsums formed also authigenically in the gas hydrate-associated environment too, most probably at the interface between the down-ward advecting sulfate-rich seawater and the below gas hydrate, which spilled calcium during its formation on Hydrate Ridge. The two distinct forms of crystal intergrowth, which are the granular mass of series single gypsum crystals at core SO143/TVG40-2A and the microsphere of gypsum crystals accompanied with detrital components at core SO143-221 respectively, indicate that they precipitated most likely in different interstitial water dynamic environments. So, the distinct authigenic gypsums found in gas hydrate-associated sediments on Hydrate Ridge could also be believed as one of the parameters which could be used to indicate the presence of gas hydrate in an unknown marine sediment cores.Erwin Suess Dirk Rickert 2004Science China Earth Sciences2004,47,3:10
5Indicators of δ^(13)C and δ^(18)O of gas hydrate-associated sediments显示文摘The analyses of δ13C and δ18O of gas hydrate-associated sediments from two cores on Hydrate Ridge in Cascadia convergent margin offshore Oregon, eastern North Pacific show the values of δ13C from-29.81‰ to -48.28‰(PDB) and δ18O from 2.56‰to 4.28‰ (PDB), which could be plotted into a group called typical carbonate minerals influenced by the methane in cold venting. Moreover, the values of δ13C and δ18O show a consistent trend in both cores from top to bottom with increasing of δ13C and decreasing of δ18O. This trend could be explained as an effect caused by the anaerobic oxidation of methane (AOM) in depth and the oxygen fraction during the formation of gas hydrate in depth together. These characteristics of δ13C and δ18O indicate that the gas hydrate-associated sediments are significantly different from the normal marine carbonates, and they are deeply influenced by the formation and evolution of gas hydrate. So, the distinct characteristics of δ13C and δ18O of gas hydrate-associatedE. Suess 2002Chinese Science Bulletin2002,47,19:2
